CO2 Reforming of CH4 on Co-Containing Supported Catalysts
Abstract
Mono- and bimetallic cobalt-containing catalysts supported on alumina have been investigated in the reaction of interaction between carbon dioxide and methane at variation of experiment temperature and pressure. It was shown, that the bimetallic catalysts have a high activity in this reaction in compare with monometallic ones. The main reaction products are carbon oxide, hydrogen, water and oxygenates. The yield of latter reaches 30% at certain conditions (P > 0.5 MPa, T < 853 K). The maximum conversion of both methane (100%) and carbon dioxide (94%) is reached at lower pressure (0.1 MPa) and 1023 K. In these conditions the synthesis-gas is a main reaction product. One of the advantages of the bimetallic catalysts is their resistance to coke formation.
