AB - Gasification could play an important role in the treatment of municipal solid  wastes. However, some problems may arise when using unsorted materials due to  the difficulties of obtaining a feed with consistent physical characteristics  and chemical properties. To overcome this problem, a new type of gasifier  consisting of three stages, namely a pyrolytic stage followed by gasification  and a reforming stage, was considered. Theoretical calculations made on the  proposed gasification scheme shows better performance than a previously  studied two-stage gasifier because of its ability of reaching the same final  temperature of the syngas with a lower oxygen injection and a better oxygen  partition ratio between the stages. The reduced amount of oxygen allows to  obtain an improved syngas quality with higher return in the final products,  such as hydrogen, electricity and so on.
