摘要

采用新的合成方法制备了磷化镍加氢脱氧催化剂Ni2P-O/MCM-41。考察了所制备的催化剂对苯并呋喃加氢脱氧反应的影响,考察了反应温度、反应压力和H2/液比对催化剂加氢脱氧反应的影响。采用拟一阶模型描述了Ni2P-O/MCM-41催化剂上苯并呋喃加氢脱氧反应动力学。根据该模型确定了不同温度下的反应速率常数k1-k5。在533 K时,2-乙基苯酚in生成乙苯的转化率开始急剧提高,无o产物乙基环己烷的收率开始迅速提高。在573 K、3.0 MPa、H2/液比为500 (V/V)的条件下,ni2o - o /MCM-41对苯并呋喃的转化率达到93%,无o产物的总收率为91%。接触时间分析表明,Ni2P-O/MCM-41催化剂不有利于去甲基化。

Reactivity and kinetic studies of benzofuran hydrodeoxygenation over a Ni2P-O/MCM-41 catalyst
A nickel phosphide hydrodeoxygenation catalyst (Ni2P-O/MCM-41) was prepared using a new synthetic method. The as-prepared catalyst was evaluated in the hydrodeoxygenation of benzofuran, and the effects of reaction temperature, pressure, and the H2/liquid ratio were investigated. A pseudo first-order model was employed to describe the reaction kinetics of benzofuran hydrodeoxygenation over the Ni2P-O/MCM-41 catalyst. The reaction rate constants (k1–k5) at different temperatures were determined according to this model. At 533 K, the conversion of 2-ethylphenol in to ethylbenzene began to increase dramatically, and the yield of O-free product, ethylcyclohexane, started to increase rapidly. At 573 K, 3.0 MPa, and a H2/liquid ratio of 500 (V/V), the conversion of benzofuran over Ni2P-O/MCM-41 reached 93%, and the combined yield of O-free products was 91%. Contact time analysis indicated that demethylation was not favored over the Ni2P-O/MCM-41 catalyst.
