Abstract

The invention belongs to the technical field of refining of high-purity titanium tetrachloride, and particularly relates to a catalytic organic matter additive as well as a preparation method and application thereof. The catalytic organic auxiliary agent is prepared by compounding organic base oil, paraffin, naphthenic hydrocarbon, aromatic hydrocarbon and metal oxide according to a specific mass ratio of (40-70): (2-10): (10-40): (5-10): (2-10). Wherein glycerin is selected as the organic base oil, naphtha is selected as the paraffin, cyclohexane is selected as the cycloalkane, C9 aromatic hydrocarbon is selected as the aromatic hydrocarbon, and aluminum oxide is selected as the metal oxide. According to the invention, the organic auxiliary agent has excellent catalytic cracking performance; in the process of removing vanadium from high-vanadium titanium tetrachloride, the catalyst can quickly react with vanadium compounds, the vanadium removal efficiency is remarkably improved, meanwhile, the unit dosage of organic auxiliaries for removing vanadium is greatly reduced, and the catalyst has process applicability and economical efficiency and is suitable for the refining link of the high-vanadium titanium tetrachloride in the production of titanium dioxide and titanium sponge.
