What is the mechanism of vanadium removal from mineral oil in TiCl4 refining?

A small amount of organic matter is added to TICL4 and mixed evenly, and the carbonization temperature of organic matter (generally 120-1380) is heated to carbonize, and the new activated carbon reduces VOCl3 to V OCL2 precipitation. It is also believed that the activated carbon adsorbs vanadium impurities at the same time to achieve the purpose of vanadium removal.

Everyone can be together**.

Summary. The vanadium removal process is divided into two steps: the first step is to manufacture TICL3 slurry, add aluminum powder to TICL4, heat it to a certain temperature under nitrogen protection, and introduce chlorine gas to chlorinate part of the aluminum powder to form ALCL3; Under the catalytic action of Alcl3, the aluminum powder reacts with TiCl4 to form TiCl3, that is, the following reaction occurs: 2Al(S)+3Cl2(G) =2A1C13(S, 1)(1)3TiCl4(L)+Al(S) =3TiCl3(S)+AlCl3(L, S)(2) reacts to finally form a solid-liquid mixture of TiCl4 liquid and TiCl3 and AlCl3 solids, which is called TiCl3 slurry. In the second step, the TiCl3 slurry is added to the crude TiCl4 to remove vanadium, that is, the following reaction occurs: VOCl3 (1)+TiCl3 (S) = VOCl2 I (S)+TiCl4(I).

Write out the + reaction formula of the common method of crude TICL4+ chemical vanadium removal in industry.

Hello dear! I've seen your question and I'm trying to sort out the answer, and I'll get back to you in five minutes, so please wait a minute

Will there be an answer.

Kiss. The answers are summarized below

Industrially, crude TICL4 vanadium removal is widely used by chemical methods, using copper wire, aluminum powder, H2S, and organic matter as the vanadium removal reagent for state rotten people, and the vanadium removal reagent is reduced to low price (+3 or +4 valence) and formed a precipitate, so as to realize the removal of vanadium.

The content of V2O5 in the vanadium slag is as high as 15 30, which can be used as a raw material for the extraction of V2O5.

It's gone. The vanadium removal process is divided into two steps: the first nuclear lap step is to manufacture TICL3 slurry, add aluminum powder to fine TICL4, heat it to a certain temperature under nitrogen protection, and introduce chlorine gas to chlorinate part of the aluminum powder to form ALCL3; Under the catalytic action of AlCl3, the reaction of aluminum powder and TiCl4 anti-branched tung should form TiCl3, that is, the following reaction occurs: 2Al(S)+3Cl2(G) =2A1C13(S, 1)(1)3TiCl4(L)+Al(S) =3TiCl3(S)+AlCl3(L, S)(2) react to finally form a solid-liquid mixture of TiCl4 liquid and TiCl3 and AlCl3 solids, which is called TiCl3 slurry. In the second step, the TICL3 slurry was added to the crude TICL4 to remove vanadium, that is, the following reaction occurred: VOCl3 (1)+TICL3 (S) =VOCl2 I (S)+TICL4(I).

We'd be glad to help you

I'll give you five stars.

Summary. It depends on what kind of vanadium slag (raw material) you have. If vanadium iron ore is extracted from vanadium, it can still be used to smelt iron. If it is a stone coal vanadium mine, the vanadium can be used to produce cement bricks. If it is other industrial vanadium slag, it depends on the nature of its tailings.

The use of vanadium slag: the use of the remaining vanadium slag after vanadium extraction. Can the residual vanadium slag be used as a mineral powder building material after vanadium extraction?
