Methane can be converted to olefins (principally ethylene) in high yields using an integrated recycle system that includes a catalyst for the oxidative coupling reaction. A membrane contactor has been used to facilitate the complexation of olefins with aqueous Ag+ ions. The olefins are released from the complexes at elevated temperatures and are recovered in nearly pure form. Alternatively, the olefins may be converted to aromatics by replacing the membrane contactor with a Ga/H-ZSM-5 zeolite catalyst. With both variations of the system, product yields greater than 70% have been obtained during continuous operation. 1998 Elsevier Science B.V. All rights reserved.
