Abstract:
A process for detoxifying toxic waste materials by steam reformation through endothermic gasification reactions, said process comprising the steps of:(a) forming a bed of solids in a first reaction vessel having heating conduits therein so as to immerse said conduits in said bed of solids;(b) indirectly heating said bed of solids in said first reaction vessel and causing said endothermic gasification reactions by providing heat to said conduits and indirectly transferring said heat from said conduits to said bed of solids;(c) injecting steam into said bed of solids to create a fluidized bed of solids;(d) depositing said toxic waste materials onto said fluidized bed of solids;(e) forming a partially reformed toxic gas in said first reaction vessel through endothermic gasification reactions; and(f) transferring said partially reformed toxic gas from said first reaction vessel to a second reaction vessel for further processing.
