负载银阳离子的H-ZSM-5（Ag/H-ZSM-5）在C2 H4存在下催化CH 4转化为高级烃如C3 H6。考察了反应温度等反应参数的影响。在673 K时甲烷的最大转化率为13.2 mol%. C_2H_4与~（13）C标记的甲烷（~（13）CH_4）反应生成单一的~（13）C标记的丙烯（~（13）CC_2H_6）和H_2，而在H-ZSM-5上没有观察到~（13）CC_2H_6的生成。这些结果表明，13 CC 2 H 6的形成是通过C2 H 4与13 CH 4的反应进行的，并且13 CH 4的活化是在银阳离子上进行的。Ag/H-ZSM-5也催化了
C3 H6和苯与CH 4反应，分别生成丁烯和甲苯。
H-ZSM-5 loaded with silver cations (Ag/H-ZSM-5) catalyzed conversion of CH4 to higher hydrocarbons such as C3H6 in the presence of C2H4. The effect of the reaction parameters, such as reaction temperature, were examined. The maximum conversion of methane was 13.2 mol% at 673 K. The reaction of C2H4 with 13C-labelled methane (13CH4) yielded singly 13C-labelled propylene (13CC2H6) and H2, while formation of 13CC2H6 was not observed over H-ZSM-5. These results indicate that the formation of 13CC2H6 proceeds by the reaction of C2H4 with 13CH4, and that the activation of 13CH4 proceeds on silver cations. Ag/H-ZSM-5 also catalyzed the reaction of
C3H6 and benzene with CH4 to form butenes and toluene, respectively.
