Abstract

The water gas shift reaction (WGSR) is a critical step in the pre-combustion capture of CO2 from syngas streams. Recent improvements in gasification technologies have improved the prospects of municipal solid waste (MSW) gasification as a tool for waste reduction and carbon dioxide removal (CDR). This study sought to improve the understanding of a biomass carbon removal and storage (BiCRS) system in which MSW gasification is paired with the WGSR. Sixteen MSW samples were gasified in a bench scale semi-batch reactor. A promising copper based WGSR catalyst was tested for activity from 240-300 degrees Celsius and gas hourly space velocities (GHSV) 4-6 times higher than previously reported. Results indicated that the composition and productivity of syngas produced was similar to examples found in literature. The WGSR catalyst exhibited an apparent activation energy of 37.8 kJ/mol. This information can inform the design of an integrated MSW gasification and WGSR system.
