Methane Selectivity

The catalyst prepared using the AC as support showed remarkably improvement of reaction performance. The improvement of the reaction performance obtained for the AC is probably ascribed to the physical structure and surface chemistry of AC. The support and corresponding catalyst are characterized by N2 adsorption. Catalytic performance of the catalyst during FT synthesis was excellent. Syngas conversion was about 74%, whereas methane selectivity was low (~2 %).

Physical And Chemical

A type of nanomesoporous modified red mud (MRM) catalyst was prepared and utilized for catalytic methane decomposition (CMD) to produce hydrogen. The modification process significantly simplified the mineral composition of the red mud (RM); in the meantime, the physical and chemical structure of RM was changed. TEM images suggested that MRM was a kind of nanomesoporous material assembled by a number of uniformly nanoscale particles, BET results showed that the pore size distributions of MRM were ranged from 3 to 12 nm, and the specific surface area and total pore volumes of red mud improved from 8.00 m2/g and 0.08 cm3/g to 190.61 m2/g and 0.39 cm3/g, respectively. The catalytic performance of the catalysts has been tested at 800°C; the results showed that MRM exhibited much higher activity and stability than RM for CMD.
