The process will accept a wide variety of carbon-based feedstock in solid, liquid or gas form. Various feed stocks may be mixed to improve their performance, to ensure a ready feedstock supply, or to reduce feedstock cost. Blending biomass into fossil fuel feedstock enables the producer to significantly reduce their carbon footprint.
All portions of the wood may be used including leaves, roots and bark to produce cellulosic fuels. Wood pulp, sawdust and all other forms of waste wood are well suited to the process.
As with wood, all portions of plant material may be used to produce fuels including the cellulosic portion of the plant which in most cases has little commercial value and does not impact the food supply. Besides plant material, agricultural residue may include animal renderings and manure.
Municipal Solid Waste & Biosolids
The carbon-based portion of municipal solid waste stream is suitable as feedstock. Only metal, glass, earthen materials (rock, concrete etc.) and PVC plastic must be removed from the MSW stream. Rubber tires, waste oil, textiles and shingles may be used to produce fuel as can food debris, yard waste and all paper. Bio solids remaining from sewage treatment process are also suitable as feedstock.
Various grades of coal and oil shale are well suited as feedstock and produce the highest fuel yields. Various forms of low value petroleum products including coke bottoms waste oil and other products are economically available from the petroleum industry.
Natural gas from petroleum or coal bed resources is suitable as feedstock as is CO2. Industrial CO2 can be utilized as a supplemental feedstock enabling large generators of CO2 like power producers to meet new carbon emissions regulations while continuing to operate their current power generation equipment.
