GASIFICATION PYROLYSIS OF WASTE PLASTICS FOR THE PRODUCTION OF FUEL-GRADE GAS

New technologies in gasification, pyrolysis, and environmental control are allowing the use of waste materials for feedstocks in environmentally acceptable ways for the production of electricity or process heat. Ebonite and automotive shredder residue were tested in a TGA using potassium- and calcium-based catalysts, and ebonite was tested in a 1- to 4-lb/hr continuous fluid-bed reactor (CFBR). Analysis of the data determined that fuel-grade gases could be produced in short residence time periods. Gas compositions of over 50 percent hydrogen were recorded with conversions of over 90 percent. Data include carbon conversion, gas production, wastewater treatment, heavy metals analysis, and chlorine content.
