What is used in waste engine oil refining catalysts?

Due to the long-term use of waste engine oil, the viscosity decreases, impurities increase, and the waste engine oil is pyrolyzed into diesel fuel for reuse through high-temperature catalysis, turning waste into treasure, and the economic benefits are considerable. The specific technology is as follows:

1. Production equipment.

Reactors, distillation columns, spiral condensers, filtration columns.

2. Production process.

1) Waste oil pretreatment: The purchased waste engine oil is separated from the separating funnel to remove the water, and then through the 200 mesh filter cloth to remove impurities such as solids and suspended solids.

2) Feed the treated waste engine oil through the funnel into the pyrolysis reaction kettle, and note that the amount of waste engine oil can not exceed 2 3 of the reactor. After adding the waste engine oil, press 0 of the weight of the waste engine oil5%-1% compound high-temperature catalyst FAC is added, stirred to disperse it in waste engine oil.

3) Vaporization pyrolysis heats the pyrolysis vaporization reactor to 400, at this time, the waste engine oil and the catalyst are fully contacted, and the pyrolysis is converted into small molecule (CIZHZS-CZOHAZ) diesel, and then vaporized into diesel vaporized gas into the distillation tower.

4) Distillation leads the above gas into the distillation tower, and separates the diesel gas through more than a dozen trays in the tower. The tray in the rectification column should theoretically be no less than 12 pieces, and the tower height should be 3 4 meters. The diameter of the tower is not less than 30 cm, and the diesel pyrolysis gas is drawn from the top of the tower into the spiral condenser for condensation.

5) CondensationWhen the pyrolysis vaporized diesel gas passes through the condenser (the condensation temperature should be lower than 109C), the pyrolysis gas can be condensed into liquid diesel, and a small amount of non-condensable gas (the exhaust gas accounts for about 5% -10% of the weight of the waste engine oil) can be discharged by the condenser pipe, or it can be used as fuel in the human combustion appliance through the steel pipe.

China waste oil network, focusing on the waste oil industry information platform, waste oil, waste oil, waste oil purchase, waste oil procurement, waste oil regeneration, waste oil application, waste oil equipment, waste oil reagents, waste oil people, waste oil, etc., all in China's waste oil network, waste oil information all over the world.

Steps to refine diesel from used engine oil:

1) Sedimentation will allow the waste oil to stand to make the impurities drop and separate. The settling time is determined by the oil quality and oil temperature. The higher the oil temperature, the smaller the viscosity, the easier it is for impurities to fall, and the shorter the settling time. Generally, the settling time of impurities in engine oil has a relationship with the temperature in the following table.

2) DistillationPut the waste engine oil after sedimentation treatment to remove the sediment into the distillation flask. The distillation device is installed and heated for atmospheric distillation. At 180 the fraction is gasoline, and the fraction of 180 360 is diesel, leaving behind is the engine oil.

If it is known that there are no impurities such as gasoline and diesel in the waste engine oil, this step can be omitted.

3) Pickling. Place the settled, distilled oil into a large beaker.

, heat to 35, and slowly add concentrated sulfuric acid accounting for about 6 8 of the oil volume under stirring.

Add in 30 minutes). At this time, the concentrated sulfuric acid reacts with the gum and asphalt-like impurities in the waste engine oil.

In order to remove these sulfonated impurities, 10 caustic soda solution accounting for 1 volume of engine oil is added to play the role of coagulant and accelerate the stratification of impurities. After adding alkali, stir for 5 minutes, and let stand for a period of time, there will be obvious delamination, and the upper layer of oil is yellow-green, without impurities such as black particles.

4) Caustic washing: This step is to remove the organic acids in the waste engine oil and neutralize the sulfuric acid remaining during pickling. Add the pickled oil to another beaker, heat to 90, and slowly add sodium carbonate to 5 the oil mass under stirring.

powder, 20 minutes after the oil to check the acidity and alkalinity. Take two tubes and add 1 ml of distilled water each.

One of them is added with 2 drops of phenolphthalein.

reagent, the other plus 2 drops of methyl orange.

Reagent. Then add 1ml of the sample to each of the two test tubes, shake for 3 minutes, if the color of the aqueous solution layer in the two test tubes does not change, it means that the oil is neutral, and the oil should become clear at this time.

5) Filtration industry is filtered with oil purifier. Household engine oil can be filtered 2 4 times with 4 6 layers of silk cloth to obtain qualified diesel.

Note] If you know the various impurities in the waste engine oil, you can adjust the above operation steps according to the actual situation. For example, engine oil contains only solid impurities such as metal shavings, which can be separated by the sedimentation method. If only gasoline, diesel and other substances are mixed into the engine oil, it can be distilled to obtain regenerated diesel.

If only the engine oil is oxidized and deteriorated, it is enough to remove impurities such as organic acids by pickling and alkali washing.

Waste engine oil can only be refined by a recognized institution.

Summary. Dear, hello, I'm happy to answer for you, waste petroleum catalysts: can not be imported.

Dear, hello, I'm happy to answer for you, waste petroleum catalysts: can not be imported.

Pro, the process of extracting vanadium and molybdenum from a waste petroleum catalyst. By enriching molybdenum by water de-aluminum, virtual and ammonium chloride vanadium precipitation and dispersion group grip exchange method, purer ammonium vanadate and ammonium molybdate can be obtained, and platinum can be enriched and platinum from petroleum catalysts. At the same time, the use of metal aluminum as a reducing agent, the use of displacement precipitation method ** platinum partially dissolved in sulfuric acid solution, vanadium extraction technology by the more mature roasting, solution leaching, extraction and separation, firing of finished products to promote the production of ear preparation.

1.Water removal: After collecting the waste engine oil to the oil collection tank to remove the water, put it in the oil refining pot, stop heating after heating to 70 80, let it stand for about 24 hours, drain the surface of the open water, and then slowly heat up to 120 (when the oil temperature is close to 100, it should be heated slowly to prevent the oil from boiling and overflowing), so that the water evaporates, after about two hours, the oil does not turn, and the black oil and gas can come out of the oil surface.

2.Pickling: After the oil is cooled to room temperature, slowly add sulfuric acid (concentration is about 92 98) under stirring, and the acid dosage is generally 5 7 of the oil amount (depending on the degree of oil pollution).

After adding the acid, continue to stir for half an hour, and then let it stand for about 12 hours to drain the acid residue.

3.Alkali washing: re-heating the pickled oil to 80, adding soda ash (Na2CO3) under stirring, stirring well, let it stand for 1 hour, and then test it with test paper for neutral, and then let it stand for more than 4 hours to drain the alkali residue.

4.Activated clay adsorption: heat the oil to 120 140, add activated clay at constant temperature and stirring (the amount is about 3 5 of the amount of oil), after adding the activated clay, continue to stir for half an hour, stand at a constant temperature of 110 120 overnight, and filter while hot the next day.

5.Filtration: It can be filtered by an oil purifier, and qualified oil can be obtained after filtration. If there is no oil filter, the bag hanging filter method can also be used.

The above is the general operation process of purifying engine oil, but it should be based on the actual situation. If there is very little impurity water, the first step can be omitted; If the color of the oil is normal after acid and alkali treatment, there is no need to use activated clay for decolorization and adsorption.

The upstairs, don't mislead people's children if you don't understand. Search for something on the Internet to fool people!

Waste engine oil bai oil refining equipment to refine non-standard firewood.

DU Oil Process:

1. First, inject the collected waste engine DAO oil into the distillation kettle of the waste engine oil refining diesel equipment version, and make the waste engine oil boil and vaporize through the conductive hot oil heating system and fuel heating system, the impurities of the waste engine oil will continue to settle in the process of heating up, and the remaining oil and gas will enter the condensation system after being catalyzed by the catalyst.

2. Let the oil and gas pass through the catalytic tower with a double-layer structure, and the reactant in the catalytic tower can remove the gum and wax in the oil and gas produced by the waste engine oil, and the oil will become relatively clear after degumming and dewaxing.

3. After catalytic reaction, oil and gas enter the condensing system, and the oil and gas are liquefied into diesel fuel through the circulating cooling water in the condensation system and enter the temporary storage tank.

4. The diesel oil refined by the waste engine oil refining diesel equipment is introduced into the decolorization system, and the color of the diesel after decolorization is clearer and brighter.

5. The gas of the non-liquefiable part first passes through the water sealing system, and then the gas is transported to the heating chamber through a special gas nozzle for full combustion.

6. For the smoke and dust emitted by fuel combustion, the waste engine oil refining diesel equipment has specially designed a desulfurization and dust removal purification system, and the flue gas is treated and emitted white smoke (mainly water vapor and carbon dioxide), which can meet the national emission standards.

There are many types of spent petroleum catalysts, depending on the specific situation.

1. Some spent catalysts contain platinum metal (platinum), which can usually be reused even if it is deactivated.

Second, waste catalysts such as ion exchange resins are usually no longer used and are directly disposed of in an environmentally friendly manner.

If you really want to care about what metals are contained in the specific waste petroleum catalyst, you must know which catalyst is developed and what process catalyst is used. Hopefully, the above answers have been helpful to you.

First use the filtration method to remove mechanical impurities, then add 3 6% active bleaching clay and stir for 20 minutes, and then filter with a 10 micron filter bag, you will get a satisfactory new oil.

The types of metals contained in spent petroleum catalysts vary with the catalyst.

The catalyst for catalytic cracking is a rare earth Y-type zeolite, which mainly contains rare earth lanthanum. The metals contained in catalytic desulfurization and denitrification catalysts are molybdenum and nickel. The catalytic reforming catalyst contains *** platinum, which is very valuable and can be refined *** later.

This is not allowed, most of the waste engine oil is heavy oil, and although the carbon content of diesel is higher than that of gasoline, it is far from the carbon content of engine oil. If it is directly refined, it cannot be refined to diesel.
