Abstract

0The decomposition of methane, its conversion into higher hydrocarbons and reaction with CO2 over Rh/ZSM-5 catalyst have been studied in a fixed bed continuous-flow reactor. Methane decomposed on Rh/ZSM-5 above 523 K to produce hydrogen, surface carbon and a small amount of ethane. No benzene or ethylene formation was detected even at 873-973 K. The addition of CH4 to CO2 promoted the dissociation of CO2. The surface carbon exhibited less reactivity toward CO2. The reaction between CH4 and CO2 occurred rapidly above 673 K to give CO and H2 with a ratio of 1.3:1 to 1.6:1. Little carbon deposited during the reaction, attributed to the facile reactions between CHx and CO2. However, addition of more than 4-5% ethane to the reacting gas mixture resulted in a significant amount of carbon deposition and in catalyst deactivation. The extent of deactivation can be decreased by using a large excess of CO2.
