英文摘要: Modeling based analysis of catalytic CO2 reforming of methane in fixed bed (FBR) and membrane reactors (MR) has been carried out for the production of syngas. Four Ni-based catalysts have been studied separately in FBR to identify suitable catalyst on the basis of carbon formation tendency at the reactor operating conditions of temperature (973-1073 K), and CO2/CH4 molar feed ratio (CMR = 1, 2, and 3). The simulation has resulted in Ni/La2O3 as most suitable catalyst at 1073 K and CMR = 1. Addition of 10% H2 to the feed further reduces the carbon formation tendencies. Two fixed bed reactor configurations [FBR1 (Ni/La2O3), and FBR2 (Rh/γ-Al2O3)], and two membrane reactor configurations [MR1 (FBR1 + dense membrane), and MR2 (FBR2 + porous membrane)] have been evaluated by simulation to identify the favorable configuration at operating conditions for syngas production. The yields of H2 and CO are found maximum as 94.5% and 98% respectively at CMR = 1 in reactor MR1. Also the H2/CO ratio has been found close to unity at 1073 K and CMR = 1 in reactor MR1 with no significant effect of sweep gas. Hence, the membrane reactor MR1 is the best reformer configuration to produce syngas by dry reforming of methane. © 2017 Elsevier Ltd. All rights reserved. Citation statistics:
