NOVELTY - The system comprises a device containing a programmable number of processing stations (50) of 2-1000 and a series of catalysts, a unit for subjecting biomass within the stations to programmable starting temperature (Tstart) of 100-1000 degrees C, a unit for incrementing an individual processing station temperature by programmable increments ( Delta T) to produce a volatile and a thermally conductive non-volatile component, and a unit for subjecting the volatile components generated in each station through the series of catalysts to produce a renewable fuel.    USE - The system is useful for converting biomass to a combustible, renewable fuel and other chemical compounds including gasoline, diesel jet fuel or fuel blends for transportation purposes, where the biomass is: material including plant products such as bark and leaves and pellet material such as grass and wood; waste products including animal manure such as poultry derived waste; commercial or recycled material including plastic and paper; municipal waste including sewage waste; agricultural waste such as coconut shells; and agriculture feed products such as rice straw and wheat straw.    ADVANTAGE - The system is capable of easily, economically, rapidly and efficiently converting biomass to the combustible, renewable fuel with reduced energy consumption.    DETAILED DESCRIPTION - The system comprises a device containing a programmable number of processing stations (50) of 2-1000 and a series of catalysts, a unit for subjecting biomass within the stations to programmable starting temperature (Tstart) of 100-1000 degrees C, a unit for incrementing an individual processing station temperature by programmable increments ( Delta T) to produce a volatile and a thermally conductive non-volatile component, a unit for subjecting the volatile components generated in each station through the series of catalysts to produce a renewable fuel, and a unit for incrementing the non-volatile component temperature by Delta T to produce additional volatile and non-volatile components. The series of catalysts are catalytic dehydration (60), catalytic aromatization (61) and catalytic gas-upgrading (32). The temperature increment ( Delta T) is 0-200 degrees C. The biomass has a moisture content of less than 15%, and is ground to a particle size of 1/16 inch and 1 inch. A co-solvent is: added to volatile components or added to the processing stations; and generated via a syngas conversion catalyst. The Tstart is: below 300 degrees C for biomass composition comprising 20-80% lipids; 300-500 degrees C for biomass comprising 20-80% hemicellulose; and greater than 500 degrees C for biomass composition comprising 20-80% lignins. All processing stations are set at the same Tstart. A dehydration catalyst comprises any acid catalyst. The aromatization catalyst is MFI type zeolites and metal modified MFI-type zeolites. The metal modified MFI-type zeolites include metals consisting of group VIB, VIIB, VIII, IB, IIB metals. The gas-upgrading catalyst comprises metal modified MFI type zeolites. A sequence of catalysts is determined by renewable fuel yield or by temperature of devolatization of biomass components. The biomass source serves as feedstock for each processing station.
