It comprises a Group VIII and Group VIB metals, and has a acetic acid and C1-C4 dialkyl succinate, available catalysts and are prepared in the hydrogenation process.

摘要

A catalyst may be used in the hydrogenation treatment method, the amorphous support based on alumina, phosphorus, and C1-C4 dialkyl succinate, acetate, the invention, at least one group VIII includes at least one element, preferably, and a hydrogenation dehydrogenation group comprising cobalt and molybdenum, the Raman spectrum of the catalyst hair Gin heteropolyanion (990cm ^-1 and / or 974) of the group VIB element and , and C1-C4 dialkyl succinate, and including the strongest band is characteristic of acetic acid (896cm ^-1), relates to a catalyst. Preferably, dialkyl succinate used is a dimethyl succinate, the main band is a 853cm ^-1. The present invention also provides a method of preparing the catalyst, the catalyst precursor, the elements, in particular, molybdenum Group VIB and Group VIII - includes a pair of cobalt, and phosphorus, which are introduced by impregnation , then allowed to dry at 180 ℃ temperatures below was impregnated with (if this object is not introduced completely already pre) Phosphorus compound dialkyl succinate and acetate, then, after maturation, 180 ℃ allowed to dry to a lower temperature, is then sulfurized in some cases, to a method. The present invention relates to the use of the catalyst in the hydrogenation process in any manner.
