Biogas reforming by the honeycomb reactor for hydrogen production

摘要

In this study, it was proposed that the Ni/porous-CeO2 coated cordierite honeycomb reactor could enhance the performance of biogas reforming for hydrogen production, compared with the packed back reactor. Current results suggested that the conversion methane and yield of hydrogen using honeycomb were increased by 22.24% and 72.52% for biogas reforming and 43.12% and 41.29% for methane steam reforming, compared with packed bed reactor at 900 degrees C and WHSV = 5hr(-1). With proposed honeycomb reactor for the reaction, methane conversion in biogas reforming was low at the temperature below 500 degrees C and was higher than 80% at the temperature over 700 degrees C and WHSV = 3hr(-1). H-2 and CO were the major product at the higher temperature. However, conversion of methane, yield of H-2, and yield CO were lower than those in the methane steam reforming. Thus, proposed catalyst and the reactor were highly effective for the hydrogen production from the biogas reforming. Copyright (C) 2015, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.
