Receipt of new catalysts used in the synthesis of acetaldehyde by separating the catalyst CCP into component parts

Abstract

New catalysts have been developed and studied for the synthesis of acetaldehyde and acetone in combination with acetylene hydration. The composition of the feedstock CCP catalyst used in the acetaldehyde synthesis was analyzed and identified. Based on the analysis results, active cadmium oxide was separated from the CCP catalyst composition, and new BCC-1, BCC-2, BCC-3, BCC-4, BCC-5, BCC-6, BCC-7, BCC-8, BCC-9 catalysts were prepared. These catalysts were tested, and during the acetaldehyde synthesis process, the BCC-7 catalyst yielded a high efficiency (65.7%). Optimal conditions were determined for the synthesis of acetaldehyde and acetone. Bentonite mineral was used as a core in the preparation of this catalyst. There are different brands of bentonite mineral, and Bentonite (PBG) brand mineral was used for BCC-7 catalyst. The high content of aluminum oxide in this mineral increases the strength of the catalyst.
