Gasification

Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2). This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam presBiomass gasification has been studied widely as an efficient and sustainable technology for the generation of heat, production of hydrogen and ethanol, Sustainable energy: A review of gasification technologies

Hydrogen-rich gas production from the gasification of biomass

In this paper, we investigated the characteristics of the aqueous phases (APs) derived from different agricultural wastes (e.g., peanut and wheat straws) and the co-gasification of cotton stalk (CS) and APs. The functional groups and pyrolysis behavior of the APs at different hydrothermal temperatures (160 °C–300 °C) were analyzed by FTIR gasification technology is one of the leading-edge technologies available to harness this energy ( Pourali, M. 201 0).

A review on hydrothermal carbonization of biomass and plastic

An integrated technology by combining biochemical (e.g., anaerobic digestion, gas fermentation, carbon chain elongation) with thermochemical processes (e.g., HTP, pyrolysis, gasification) has been proposed to enhance the efficiency and stability of biochemical conversion, thus controlling the gas and liquid pollution produced from Gasification is often considered the baseline technology and foundation for developing many advanced carbon-based fuels and chemicals. For example, gasification is the key conversion step for converting coal to H 2, synthetic natural gas (SNG), liquid fuels, and the capture of CO 2 for sequestration.Gasification Technology SpringerLink

WTE: Gasification and Pyrolysis in Japan SpringerLink

In Japan, about 40 million tons of municipal solid wastes (MSW) are incinerated each year. Of these, about 20 million tons are used as fuel in waste-to-energy (WTE) power plants that produce about 1000 MW of electric power. Most of these waste-to-energy (WTE) plants are large-scale plants exceeding 200 t/day scale.Gasification in entrained flow reactors is now one of the most dynamically developed technologies of thermal conversion of coal. The basic, solid by-product of this process is slag, and in some cases also fly ash. In Poland, so far there have been no examples of industrial application of coal gasification. However, the high popularity of such systems [PDF] The mechanical properties of coal gasification slag as a

Fluidized-bed gasifiers suspend feedstock particles in an oxygen-rich gas so the resulting bed within the gasifier acts as a fluid. These gasifiers employ back-mixing, and efficiently mix feed coal particles with coal particles already undergoing gasification.
