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 gasification of coal, which in turn will produce synthetic gas (a mix of CO+H2). The synthetic gas can be liquefied to its fuel equivalent in presence of cobalt/ironbased catalysts at higher pressure and temperature. However, liquefied coal emits twice as much CO2 as burning oil. It also emits a large volume of SO2.

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].
