摘要：

Increasing the pressure in the oxidative coupling reaction of methane significantly increases the importance of the blank or uncatalysed reaction. The effect is so large that, at 0.4-0.6 MPa and low gas velocities, the only significant effect of the catalyst is to alter the CO/CO2 ratio in the product stream. The importance of the blank reaction can be reduced by using high linear velocities, but increasing pressure under these conditions still depresses the C2+ selectivity of the catalysts. © 1990.
