Staged Reforming

Staged reforming is a thermochemical process that converts organic material or bio waste, such as wood, dung or hay, into combustible gases containing methane, carbon monoxide and hydrogen. It was developed because single-stage reforming of bio materials produces high dust and tar yields in the resulting gas, which restrict its use; in staged reforming, gas conversion is instead carried out as a separate stage after pyrolysis. The output of staged reforming is approximately 80 percent fuel gas and 20 percent coke.
