Gasification is a process in which organic material is converted to a combustible gas, called producer gas. This producer gas mainly consists of H2, N2, CH4, CO and CO2 .The producer gas than can be used as a fuel to generate electricity, for example by means of a gas engine or gas turbine or generator. For biomass gasification several technologies can be applied, depending on scale, fuel type, ash content and ash melting behavior. For the gasification of switch grass, a fluidized bed seems to be the best applicable technology, because it can handle biomass types with a very low bulk density as well as low ash melting temperatures. Gasification of switch grass in a fluidized bed is a perfectly viable option. Feeding causes no problems and the producer gas is of good quality. Tar formation is limited to light tars and no ash slagging occurs. The only point of attention is the relatively high amount of carbon in the ash.
