摘要

在固定床微型反应器上考察了Pt/Al2O3催化剂对甲烷氢氘交换的催化性能。结果表明

在进料组成不变条件下

温度<663K时

甲烷转化率随温度增加快速升高

但随反应物流量增加而明显减小;温度>663K时

甲烷转化率几乎不随温度和反应物流量而变化;在反应温度566-793K

反应物总流量不变条件下

当HD/CH4=1.5-2.5时

甲烷转化率随HD/CH4增加而减小

进料组成发生变化时

转化率随HD/CH4的增大而明显减小。

Abstract

Properties of Pt/Al2O3 catalysts for hydrogen-deuterium exchange of methane were studied with a fixed-bed micro-reactor.The results indicated that under the same feed composition conditions

the conversion of methane increased rapidly with reaction temperature until 663 K

where it began to saturate

while it decreased with increasing flow of the reactants;at temperatures of 566-793 K

it decreased significantly with increasing ratio of HD/CH4 when HD/CH4 =1.5-2.5 and when the feed composition changed in the total flow of reactants.
