The Influence of Char Preparation and Biomass Type on Char Steam Gasification Kinetics [PDF]
Energies, 2018 A study was conducted to investigate the parameter that has influence on steam gasification kinetics between the biomass type and char preparation. Thermogravimetric analysis (TGA) was carried out on steam gasification of seven biomass samples as well as chars from three of these samples.

Steam gasification reactivity of a high-sodium coal fly ash obtained from a pilot scale CFB gasifier
International Journal of Coal Science & Technology, 2018 Circulating fluidized bed (CFB) gasification has several advantages for the utilization of low rank coals. However, the carbon content of fly ash is usually very high, which greatly influences the gasification efficiency.

CO2 char gasification: A systematic review from 2014 to 2020
Energy Conversion and Management: X, 2021 Global efforts to mitigate climate change are based on forecasts of future warmer temperatures on the earth’s surface. Climate warming is caused by the positive radiative imbalances triggered by the accumulated Greenhouse Gases (GHG) emissions.

Beneficial Use of Ash and Char From Biomass Gasification
, 2011 Biomass is likely to be a significant energy resource in the future. A common way to recover energy from biomass is through gasification where synthesis gas is produced; by-products of this process are tar and ash/char.
