Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N 2), carbon monoxide (CO), hydrogen (H 2), and carbon dioxide (CO 2).
Fermentation of biomass such as sugarcane, wheat or corn releases CO 2 as a by-product. Industry Pulp and paper mills. Cement production CO 2 produced in recovery boilers. CO 2 produced in lime kilns, such as when making cement. [17] For gasification technologies, CO 2 is produced during the gasification of black liquor and biomass such as the ...
Below is a schematic flow diagram of an IGCC plant: Block diagram of IGCC power plant, which utilizes the HRSG. The gasification process can produce syngas from a wide variety of carbon-containing feedstocks, such as high-sulfur coal, heavy petroleum residues, and biomass.
Initially biomass undergoes pyrolysis process to produce pyrolysis gases and biochar.The volatile organic compounds in pyrolysis gases further undergo gasification process to produce syngas rich in hydrogen and carbon monoxide gases which is further converted in to methanol (CH 3 OH). [3]
Bioenergy with carbon capture and storage (BECCS) is the process of extracting bioenergy from biomass and capturing and storing the carbon dioxide (CO 2) that is produced. Greenhouse gas emissions from bioenergy can be low because when vegetation is harvested for bioenergy, new vegetation can grow that will absorb CO 2 from the air through ...
Multiple types of solid fuel gasifiers are commercially available for coal, petcoke, and biomass gasification.Designs vary depending on fuel and intended application. As a result, they can differ in the composition of the syngas produced and the efficiency with which they convert coal energy content to syngas energy content - a performance parameter typically termed cold gas efficiency.

Steam and carbon dioxide can also be used as the oxidants. As the metal oxide also serves as the heat transfer medium in the chemical looping process, the exergy efficiency of the reforming and gasification processes like that for the combustion process is also higher as compared to the conventional processes.

A wood gas generator is a gasification unit which converts timber or charcoal into wood gas, a producer gas consisting of atmospheric nitrogen, carbon monoxide, hydrogen, traces of methane, and other gases, which – after cooling and filtering – can then be used to power an internal combustion ...
