”The CO2 reforming of methane is a significant research area in mitigating and transforming two greenhouse gases for the production of syngas. The reaction has been investigated for four different promoted catalysts to determine their reactant's conversion, product’s selectivity, and their respective syngas ratios.
The catalytic test was investigated under atmospheric conditions at 600⁰C for 6.5h with a WHSV of 4800 ml g-1 h-1. The conversion and selectivity of catalysts 9Al 1V-inc SAPO-34, 9Al 1Cr-inc SAPO-34, 9Al 1Ga-inc SAPO-34, and 9Al 1In-inc SAPO-34 were analyzed. The CH4 conversion for the different catalysts are, 9Al 1Cr-inc SAPO-34 (33%), 9Al 1Y-inc SAPO-34 (27%), 9Al 1Ga-inc SAPO-34 (31%), and 9Al 1In-inc SAPO-34 (32%). The Cr promoted catalyst gave the highest CH4 conversion and the highest syngas ratio of 0.7, while the In promoted catalyst gave the highest CO2 conversion of 34%. The highest CO and H2 selectivity (34% and 7%) was from 9Al 1V-inc SAPO-34 catalyst. The different conversion, selectivity, and syngas ratio obtained for these catalysts is a result of the different bimetallic metal (alloy) used on the weakly acidic zeolite support.
The heat and mass transfer limitations on the catalysts were analyzed using the Weiz-Prater criteria for internal diffusion, the Mears criterion for external diffusion, and combined interphase and intraparticle heat and mass transfer. Based on the evaluated report, there was no heat and mass transfer limitations on these catalysts”--Abstract, page iii.
