Biomass and coal cofiring gasification with pre-combustion carbon capture: Impact of mixed feedstocks on CO2 absorption using a physical solvent

Abstract

Advances in co-gasification of coal and biomass are resulting in more interest in poly-generation facilities that can produce hydrogen rich syngas for producing chemicals, fuels and energy, with much lower carbon emissions. When biomass is blended with hydrocarbon feedstocks like coal (biomass cofiring) and when the carbon dioxide (CO2) produced during the gasification process is captured using pre-combustion CO2 capture technologies, it is possible to emit less CO2 into the atmosphere than it took to grow the biomass material, resulting in net negative or low CO2 emissions. Here, we present the first carbon capture pilot plant data for CO2 removal from coal and biomass derived syngas using ..
