Biomass has became an important renewable alternative energy resource. Mill
ion tons of food sludge, which is difficult to handle because of its rank s
mell and water content, is generated in Korea. Thermochemical conversion is
one way to convert biomass to energy; it can be divided into carbonization
, liquefaction, and gasification. Carbonization of food waste was carried o
ut in a conventional stainless steel autoclave of 2 L capacity at different
temperatures. Since gasification produces hydrogen-rich synthesis gas, whi
ch can be used for methanol synthesis, gasification of carbonized solid was
studied in the fluidized-bed gasifier. The reaction parameters in the gasi
fication of carbonized solids were investigated.
