英文摘要	a single-pass process with the combination of oxidative coupling (ocm) and dehydro-aromatization (mda) for the direct conversion of methane is carried out. with the assistance of the ocm reaction over the sro-la2o3/cao catalyst loaded on top of the catalyst bed, the duration of the dehydro-aromatization reaction catalyzed by a 6mo/hmcm-49 catalyst shows a significant improvement, and. the initial deactivation rate constant of the overall process revealed about 1.5 x 10(-6) s(-1). up to 72 h on stream, the yield of aromatics was still maintained at 5.0% with a methane conversion of 9.6%, which is obviously higher than that reported for the conventional mda process with single catalyst. upon the tpr results, this wonderful enhancement would be attributed to an in-situ formation of co2 and h2o through the ocm reaction, which serves as a scavenger for actively removing the coke formed during the mda reaction via a reverse boudouard reaction and the water gas reaction as well.
