AI Technical Summary

Technical Problem

Existing catalysts are expensive, have low utilization rates of active metals, poor support stability, and produce many byproducts, which limits the production efficiency of tetramethylpiperidinol.

Method used

A catalyst with high dispersion and alkali resistance was prepared by using mesoporous zirconium-silicon composite oxide as a support, loading active metal cobalt and auxiliary metal copper or nickel, and then preparing the catalyst through solvothermal method and calcination reduction.

Benefits of technology

It achieves low-cost, high-activity, and long-term stable catalytic performance, improves the production efficiency and selectivity of tetramethylpiperidinol, and reduces the formation of by-products.
