Abstract:
1. A method for select product gas generation from solid carbonaceous materials comprising the steps of: inputting a feedstock solids carbonaceous material; subjecting said feedstock solids carbonaceous material to a pressurized environment; increasing an temperature within said pressurized environment to which said feedstock solids carbonaceous material is subjected; initially processing at least a portion of said feedstock solids carbonaceous material in a solid carbonaceous materials gasifier system; creating an initially processed carbonaceous material; subsequently processing said initially processed carbonaceous material in said solid carbonaceous materials gasifier system to generate at least some components of a select product gas; creating a subsequently processed carbonaceous material; selectively separating said subsequently processed carbonaceous material into at least a first processed materials portion and a second processed materials portion, so as to increase the purity of said select product gas; returning said first processed materials portion within said solid carbonaceous materials gasifier system; mixing said first processed materials portion with additionally input carbonaceous material; reprocessing said first processed materials portion with said additionally input carbonaceous material in said solid carbonaceous materials gasifier system to further generate at least some components of a select product gas; outputting at least some select product gas from said solid carbonaceous materials gasifier system.
