Methyl isobutyl ketone high-space-velocity hydrogenation catalyst, preparation method and applications thereof

Abstract

The invention discloses a methyl isobutyl ketone high-space-velocity hydrogenation catalyst, a preparation method and applications thereof. The catalyst is prepared from the following components in parts by weight: 12-26 parts of cobalt and 70-88 parts of a zirconium-modified alumina carrier based on 100 parts of the total weight of the catalyst, wherein the zirconium-modified aluminum oxide is analuminum oxide carrier formed by molding pseudo-boehmite powder, the pseudo-boehmite powder is prepared by using an aluminum sulfate solution containing a soluble zirconium salt as a raw material through an aluminum sulfate-sodium metaaluminate method, the zirconium content in the aluminum oxide carrier is 1-8 wt%, and the sulfate ion content is less than 0.4 wt%. The catalyst disclosed by the invention is good in stability, and has high activity and high selectivity at a low temperature.

Description

technical field

[0001] The invention relates to the field of catalysts, in particular to a catalyst for high space velocity hydrogenation of methyl isobutyl ketone, a preparation method and an application thereof. Background technique

[0002] Methyl isobutyl carbinol (also known as 4-methyl-2-pentanol, referred to as MIBC in English), is an excellent medium-boiling solvent, used as raw material for organic synthesis, mineral flotation lotion, such as extraction of silicon and nickel sulfate It can also be used as brake fluid, as a solvent for dyes, petroleum, rubber, resin, paraffin, nitrocellulose and ethyl cellulose, etc., as an inert solvent for nitrocellulose paint, which can increase the gloss and Smoothness, improved redness, used as a solvent in additive manufacturing of lubricating oils, etc.

[0003] The use of methyl isobutyl carbinol (MIBC) as a mineral flotation agent has considerable market prospects. In 2013, the global consumption of flotation agents was ab...
