dc.description.abstractThe utilization of methane has achieved great commercial significance in the last few years in the face of dwindling oil resources. One of the restrictions on a process for methane utilization is the fact that many of the gas fields in the world are in remote locations. The transport of natural gas from these fields is not easy since liquefaction of the gas is neither safe nor trivial. The first step toward methane utilization, therefore, is its conversion to a material which is easier to transport, while preserving the intrinsic versatility of a low carbon number hydrocarbon. This project reports on the development of a novel family of catalysts for the oxidative coupling of methane. The major products of the process are ethylene, ethane and carbon monoxide. One of the significant features of the catalysts is that they are active for the coupling reaction at 575 C, a temperature which is 100-200 C lower than similar processes described in the open and patent literature. This is useful since the useful products of the reaction viz. C$\\sb2$ hydrocarbons tend to oxidize completely at high temperatures, thus lowering the selectivity of the reaction. The major pathways in the reaction have been determined, and from this knowledge, a transient mode of operation for the reaction has been devised which enhances the selectivity of the reaction sizeably. The transient mode of operation (Phase locked product separation) also permits easy separation of the products with very high efficiency.
