由甲烷氧化合成乙烯是合理利用天然气和炼厂气甲烷的重要途径。近年来竞相报道了许多固相催化剂,但都未达到下述三项基础指标:(1)在高甲烷分压(>0.4atm)下C_2稳定产率>30％,其中C_2H_4占大部分;(2)在(1)的前提下,C_2稳定选择性>80％;(3)催化剂使用寿命较长。本文在前文的基础上选用具有表面 The synthesis of ethylene from methane oxidation is an important way to make rational use of natural gas and refinery methane. In recent years, many solid-phase catalysts have been competitively reported, but none of the following three basic indicators have been met: (1) C 2 stable yield> 30% at high methane partial pressure (> 0.4 atm), with C 2 H 4 accounting for the most part; 2) under the premise of (1), C 2 has a stable selectivity of> 80%; and (3) the catalyst has a longer service life.
