CO2 conversion to syngas through the steam-biogas reforming process

摘要: Abstract The steam-biogas reforming (SBR) process to convert biogas a high hydrogen syngas was studied experimentally and using Aspen Plus simulations. An integrated renewable power generation system where the SBR coupled with Solid Oxide Fuel Cell (SOFC) model. experimental work conducted over metal-foam-coated [Pd(7)-Rh(1)]/[CeZrO2(25)-Al2O3(75)] catalyst in Heat Exchanger Platform (HEP) reactor. simulations were for feeds CH4/CO2 ratios of 40/60, 50/50 60/40 at S/C 1.00–2.00 temperature range 873–1123 K. data show that positive CO2 conversion attainable only temperatures higher than 1073 K, although equilibrium based simulation predicts through most operating range. Energy efficiency overall approximately 40% 948 K above. Coke formation Pd-Rh estimated be 1.05–2.88% carbon input system. Fresh used catalysts characterized by BET adsorption, porosimetry, CO chemisorption Scanning Electron Microscopy. results proposed can provide viable approach utilizing distributed methane resources localized generation.
