TWO-STAGE GASIFICATION PROCESS OF SOLID ORGANIC COMPOUNDS

The research focused on two-stage high temperature gasification under steam atmosphere, at atmospheric pressure conducted organic solid compounds for maximum energy potential recovery with respect to product transformation during the process and its influence on final results. The work aimed to establish the dependence of second gasification stage on the first devolatilization one together with the connection: process parameters -reactions kinetics. The approach was justified by the products different physical-chemical structures and carbonization parameters: pressure, temperature and residence time influence on the char formation and its physical characteristics. Furthermore the second reason for this approach was the advantages of two-stage pyro-gasification process, compared to direct gasification one.
