TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The consumable catalyst comprises: a zeolite catalyst; a zeolite/clay catalyst; kaolin, zeolite, amorphous silica and alumina; or at least one of aluminum phosphate and rare earth elements. The zeolite has a pore size of 1-200 nm. (I) further comprises rare earth elements (0-10 wt.%). (I) preferably comprises: 12 wt.% kaolin, 28.2 wt.% zeolite, 28.2 wt.% amorphous silica, 28.2 wt.% alumina, 2.5 wt.% aluminum phosphate and 1 wt.% rare earth elements; or 12 wt.% kaolin, 28 wt.% zeolite, 28 wt.% amorphous silica, 28 wt.% alumina, 2.5 wt.% aluminum phosphate and 1.5 wt.% rare earth elements.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The feedstock handling subsystem comprises a feedstock hopper, a feedstock auger and a feedstock plug, sealing valve and a feedstock preparation subsystem operable to perform a kettle operation at elevated temperature to drive off water from the feedstock. The system further comprises a vacuum pressure subsystem comprising a vacuum pump subsystem operable to generate vacuum pressure to control vacuum pyrolytic gasification and to drive the gaseous effluent through at least one condensation station that performs liquefaction. The combining and mixing subsystem comprises a consumable catalyst feeder operable to meter catalyst into the feedstock in a controlled ratio to support conversion of the feedstock to biofuel, and an extruder for mixing the feedstock and the catalyst to produce the feedstock/catalyst mixture. The vacuum pyrolytic gasification subsystem comprises a vacuum reactor operable to heat the feedstock/catalyst mixture under controlled conditions of temperature and vacuum pressure to produce the gaseous effluent. The liquefaction subsystem comprises: a distillation tower operable to perform a first condensing operation that condenses at least one gaseous intermediate into at least one heavy liquid fuel; a liquid fuel condenser operable to receive the gaseous effluent that does not condense in the distillation tower and to condense the gaseous effluent into at least one medium weight or light liquid fuel; and a reflux subsystem operable to separate the medium weight or light liquid fuel from non-condensable fuels of the gaseous effluent for separate recovery of the medium weight or light liquid fuel and the non-condensable fuels. The reflux subsystem is further operable to return a portion of the medium weight or light liquid fuel to the distillation tower to assist condensing.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The vacuum pyrolytic gasification and liquefaction process comprises: heating the feedstock/catalyst mixture under selected conditions of temperature (preferably 260-480 degrees F) and vacuum pressurizing the biomass/catalyst mixture at a vacuum pressure of 5-25 inches of mercury to produce the gaseous effluent; and subjecting the gaseous effluent to condensing to produce the liquid biofuel. The step of condensing comprises: primary condensing of the gaseous effluent to produce at least one heavy liquid fuel; or secondary condensing of the gaseous effluent to produce at least one light or medium weight liquid fuel, where at least one uncondensed gaseous liquid fuel remains after the secondary condensing. The consumable catalyst is selected according to the feedstock and desired species of the biofuel. The feedstock undergoes water removal prior to the combining with the consumable catalyst. The feedstock/catalyst mixture comprises a feedstock-to-catalyst weight ratio of 100:1 to 1000:1. The vacuum pyrolytic gasification and liquefaction process further produces at least one vacuum pyrolytic gasification residue comprising a potassium-containing compound, which is potash. Preferred Components: The biomass material is oil/lipid biomass products and/or lignocellulosic biomass products. The oil/lipid biomass products are plant-based oil/lipid biomass products (including algae or other aquatic species, corn, beans, legumes and seeds), animal-based oil/lipid biomass products (including animal fats, tallow, fish oils and fat), or oil and grease waste streams (including yellow and brown greases, sewage sludge, animal renderings and manure). The lignocellulosic biomass products are wood and gum products (forest derivatives) including wood chips, saw dust and timber slash, mill scrap, paper products, grasses, sugar crops, starch crops, grain crops, agricultural wastes including cuttings, stalks, and chaff or municipal waste including yard clippings and waste paper. The biofuel: comprises hydrocarbon species which are paraffins, isoparaffins, naphthenes, olefins and aromatics; and is a light liquid fuel having a carbon content of 7-11C (gasoline range fuels), a medium weight liquid fuel having a carbon content of 12-15C (kerosene range fuels) or a heavy liquid fuel having a carbon content of 16-20C (diesel range fuels). EXAMPLE - A consumable catalyst (comprising kaolin (12 wt.%), zeolite (28.2 wt.%), amorphous silica (28.2 wt.%), alumina (28.2 wt.%), aluminum phosphate (2.5 wt.%) and rare earth elements (1 wt.%)) was mixed with a feedstock (comprising dried salt water algae and flocked wood) to produce a feedstock/catalyst mixture (250:1). The mixture was heated in a reactor vessel at 668-681 degrees F under a pressure of 13-15 inches of mercury for 120 minutes to produce syngas (22 pounds) and liquid fuel (58 pounds) comprising paraffins and isoparaffins (14.2%), naphthenes (19.9%), olefins (35.2%) or aromatics (30.7%).
