ABSTRACT:
An apparatus for treating wastes includes a fluidized bed reactor for partially combusting the wastes at a relatively low temperature, and a separate relatively high temperature reactor for separate gasification of gaseous material and char from the first gasification. This synthesis gas thus formed is cooled, subjected to a conversion operation in a converter to produce hydrogen.
