Gasification of biomass is a thermochemical process in which solid biomass is treated with a limited amount of gasifying medium to convert it into valuable gases such as Methane (CH 4), Carbon Dioxide (CO 2), Carbon Monoxide (CO), and Hydrogen (H 2) and a solid residue named gases can be further converted to liquid fuels via the FT process or heat and energy for power generation ...

Coal gasification is a process in which coal is converted to a lowgrade gas; it can be regarded in many ways as fuelrich combustion. Oxygenblown coal gasifiers operate at overall equivalence ratios (fuel to oxidizer ratio normalized by fuel to oxidizer ratio required to fully oxidize fuel) greater than two. Commercial or nearcommercial ...

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.

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.
