摘要

采用等体积浸渍法制备Na、K改性的Ni₃P/CePO₄催化剂前驱体,通过氢气等离子体法还原得到催化剂,利用XRD和TEM对制备的催化剂进行表征,研究了催化剂的晶相结构,并考察了催化剂在糠醛水相加氢重排反应中的催化反应性能。结果表明,经过焙烧的Na-Ni₃P/CePO₄催化剂具有高的环戊酮选择性(82.6%),而免焙烧的Na-Ni₃P/CePO₄催化剂表现出高加氢活性,糠醛转化率可达到100%。

Abstract

Na and K modified Ni₃P/CePO₄ catalyst precursor is prepared through co-impregnation method,and is reduced to catalyst by hydrogen plasma method.The prepared catalyst is characterized by XRD and TEM,and its crystal phase is studied.The catalytic performance of the prepared catalyst is evaluated in the aqueous-phase hydrogenation rearrangement of furfural.Experimental results show that the calcined Na-Ni₃P/CePO₄ catalyst performs higher selectivity to cyclopentanone (82.6%),while the non-calcined Na-Ni₃P/CePO₄ catalyst shows higher hydrogenation activity,with a complete conversion of furfural.
