镍钌/黏土催化糖醇混合物氢解制低碳二元醇
Hydrogenolysis of Sugar Alcohol Mixture to Low Carbon Dihydric Alcolols over NiRu/Ciay Catalyst
摘要
Abstract
A NiRu/clay bimetallic catalyst was prepared through a two-step method(wet blending and then precipitation) and was used in the hydrogenolysis of C5 and Ct sugar alcohol mixture to ethylene glycol, propylene glycol and butylene glycol. Compared to Ni/clay catalyst prepared only through the wet blending, the activity of the catalyst prepared through the two-step method was approximate(the conversion of the C5 and C6 sugar alcohol mixture was 91.21%) and the selectivity increased from 38.88% to 74.09%. The catalysts were characterized by means of TEM and XPS. The results indicated that Ru deposited on the Ni/clay catalyst without disrupting Ni2+particles which could increase the selectivity due to synergistic effect between Ru and Ni.关键词
