WERKWIJZE VOOR HET SELECTIEF HYDROGENEREN VAN EEN MENGSEL VAN IN VERSCHILLENDE MATE ONVERZADIGDE KOOLWATERSTOFFEN.

摘要

This invention relates to a process for selectively hydrogenating unsaturated hydrocarbons in the liquid phase, in the presence of a catalyst comprising palladium on an alumina carrier, said catalyst resulting from contacting alumina agglomerates of at least a 120 m2/g specific surface with steam at 110 DEG - 300 DEG C. for at least 15 minutes, drying the resulting agglomerates, heating them to a temperature from 500 DEG to 1,200 DEG C., so as to obtain alumina agglomerates of a 40 - 100 m2/g specific surface, admixing said agglomerates with a palladium compound and heating up the resulting mixture to 300 DEG - 600 DEG C.
