Development of environmentally friendly way of conversion of natural gas to high value chemical products is an actual problem. The oxidative coupling of methane (OCM) to ethane and ethylene is an attractive way of the one-stage methane utilization. In recent years, a great deal of effort has been directed towards OCM using mixed ionic-electronic conducting membranes (MIECM) but only a few examples obtained a C2 yield larger than 30%. It was postulated that for the further enhancement of C2 yield in membrane reactor, efficient catalyst systems should be provided and the development of a high permeation flux MIEC membrane alone is not a sufficient strategy for the successful industrial implementation of an OCM membrane reactor. Thus the goal of this study is a creation of an efficient catalyst for OCM to be used in catalytic membrane reactor (CMR). The La-Sr/CaO and Mn-Na-W/SiO2 type catalysts were shown to be among the most suitable for this purpose, and therefore we have undertaken a systematic synthesis, physicochemical and catalytic characterization study of the series of such compositions and their modifications, with a perspective of integration into the CMR.
