Problems solved by technology

The reason for this problem is that the pyrolysis of organic matter is not complete, and a large amount of viscous polymers are produced, which leads to equipment sticking, blockage, etc., which affects the continuity of the titanium tetrachloride refining process and increases the processing capacity of vanadium. Slag and cost of maintaining equipment

Abstract

The invention belongs to the field of organic matter refined titanium tetrachloride, in particular to a compound organic matter for a vanadium slag reduction crude titanium tetrachloride vanadium removal process. The compound organic matter is prepared from mineral oil, unsaturated fatty acid, silicate and sulfonate in a mass ratio of (40 to 55) to (35 to 50) to (2 to 8) to (2 to 8), wherein the mineral oil is industrial white oil; the industrial white oil is industrial-grade 26# white oil; the unsaturated fatty acid is linoleic acid; the silicate is aluminum silicate; the sulfonate is sodiumalpha-olefin sulfonate. The compound organic matter has the advantages of high vanadium removing efficiency, high adsorption capacity, and capability of ensuring stable vanadium removing effect on thepremise of the reduction of vanadium slag.

Description

technical field [0001] The invention belongs to the field of refining titanium tetrachloride with organic matter, and in particular relates to a complex organic matter for vanadium removal process of vanadium slag reduction crude titanium tetrachloride and a preparation method thereof. Background technique [0002] Titanium dioxide, also known as titanium dioxide, is considered to be a white pigment with the best performance in the world. Titanium tetrachloride is an intermediate product for preparing titanium dioxide, and the purity of titanium tetrachloride directly affects the chroma of titanium dioxide. The existing titanium tetrachloride refining process is mainly based on organic matter refining. This vanadium removal process will cause problems such as equipment sticking and blockage after running for a period of time. The reason for this problem is mainly because a large amount of high molecular polymer by-products are produced in the process of cracking organic ma...
