PROCESS FOR COMPLETE GASIFICATION OF CARBONACEOUS MATERIALS

摘要

Process for the complete gasification of carbonaceous materials wherein a thorough pyrolysis of the material to be gasified is effected, preferably in a reducing medium, which provides on one hand pyroligneous vapors, and on the other hand a high carbon content product characterized by the fact that a thorough degradation of all or part of said pyroligneous vapors is effected providing a gas of which the anhydrous portion contains only non-condensable products in ordinary conditions of temperature and pressure, and characterized by the fact that said gas is brought back onto said product with a high carbon content being gaseified and the purified gas produced is extracted. The process provides a gas containing nothing but heavy pyrolysis products and it can be used without chemical purification or in a thermal motor.
