K改性Ni/β-Mo2C催化剂用于CO加氢反应研究
Preparation of K doped Ni/β-Mo2C and its performance for CO hydrogenation
摘要
Abstract
K doped Ni/β-Mo2C catalysts were prepared by sol-gel method and temperature programmed carburization method, and their structure and morphology were characterized by XRD, BET and TEM. The effect of K amount on the catalytic behavior of the catalysts for hydrogenation of CO to higher alcohols was investigated in a fixed bed reactor. The results showed that the K doped Ni/β-Mo2C catalysts exhibited high activity for CO hydrogenation reaction and C1-4 alkanes were the main products. The addition of an appropriate amount of K could greatly increased the surface area of the Ni/β-Mo2C catalysts and enhanced both activity and selectivity towards C2 + alcohols. However, when an excessive amount of K was added, the surface area of the catalysts decreased and inert K2MoO4 was formed, which resulted in the decrease of the catalytic activity.关键词
