Cogasification of biomass and coal is an alternative that increases the reliability of power plants while reducing CO 2 emissions [125]. Cogasification of biomass and coal has exhibited a synergistic effect, with many studies reporting that with higher amount of biomass the gasification reaction was promoted [125], [126], [127].

Updraft Gasifiers These type of gasifiers are one of the simplest and most common types of gasifier for biomass. With updraft gasification, the fuel is supplied at the top and the air at the bottom so that fuel moves against the air flow. Downdraft Gasifiers The downdraft design is essentially the same as the updraft design except that ...

Process: Coal gasification is a process in which coal is partially oxidised with air, oxygen, steam or carbon dioxide to form a fuel gas. This gas is then used instead of piped natural gas, methane and others for deriving energy. Insitu gasification of coal or Underground Coal Gasification (UCG) is the technique of converting coal into ...

Fluidizedbed gasifiers suspend feedstock particles in an oxygenrich gas so the resulting bed within the gasifier acts as a fluid. These gasifiers employ backmixing, and efficiently mix feed coal particles with coal particles already undergoing gasification. To sustain fluidization, or suspension of coal particles within the gasifier, coal of ...

The process involves pumping oxygen and steam through a small borehole into the coal seam to produce a small and controlled combustion. Unlike coalbed methane, therefore, the actual coal is converted from a solid state into gas. The hydrogen, methane, carbon monoxide and CO2 are then siphoned off through a second borehole.

Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an insitu gasification process, carried out in nonmined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide.
