Abstract: Vapor-phase aldehyde hydrogenation catalyst of the VAH type is of the Cu-Zn-Al system and suitable for butanol and octanol production by means of butyl aldehyde and octane aldehyde vapor-phase hydrogenation method. Using the special step-by-step mixing and continuous co-precipitation method, copper crystalline grains, the active component, are highly dispersed to effectively inhibit dehydration activity of catalyst, improving the activity, selectivity and thermal stability of catalyst. The hydrogenation activity of catalyst is higher than 99.5 percent, the selectivity higher than 98.5 percent and the service life more than five years. This catalyst has been industrially used in many sets of butyl octanol facilities at home. The facilities are stable in operation, bringing about localization of vapor-phase aldehyde hydrogenation catalyst. The product reaches the country’s high-quality standard while the functions of the catalyst are in line with the advanced international standards.

Key words: aldehyde hydrogenation, catalyst, butyl alcohol, octyl alcohol, localization, independent creation
