Non-sulfide catalyst for hydrodeoxygenation of lignin derivative and lignin and preparation method of non-sulfide catalyst

Abstract

The invention belongs to the technical field of hydrodeoxygenation reaction, and particularly relates to a non-sulfide catalyst for hydrodeoxygenation of lignin derivatives and lignin and a preparation method of the non-sulfide catalyst. The non-sulfide catalyst with an active component of NiMoTe or CoMoTe is prepared from a nickel source / cobalt source, a molybdenum source and a tellurium source through an impregnation method. Compared with the existing sulfide catalyst, the catalyst provided by the invention fundamentally avoids the problems of sulfur loss and sulfur supplementation caused by unstable active phase of the traditional sulfide catalyst. In the aspect of hydrodeoxygenation reaction, the catalyst provided by the invention has higher hydrodeoxygenation catalytic activity and more excellent reaction stability. In addition, the catalyst is simple in preparation process, environmentally friendly, suitable for efficient hydrodeoxygenation conversion of lignin and derivatives thereof and wide in industrial application prospect.
