NOVELTY - Converting (I) biomass to renewable fuels, comprises: providing device containing programmable number of processing stations (50) and series of catalysts; subjecting biomass within stations to at least one programmable starting temperature; incrementing individual processing station temperature by programmable increments to produce volatile and non-volatile component; and contacting the volatile component with aromatization catalyst (61) to produce first product which on cooling to temperature of 1-20 degrees C produces second volatile component, first renewable fuel and water.    USE - The method is useful for converting biomass to renewable fuels (claimed) including gasoline, diesel and jet fuel used for transportation.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) converting (II) biomass to renewable fuels, comprising: providing the device containing the programmable number of processing stations and the series of catalysts; subjecting hemicellulose-rich biomass within the stations to the programmable starting temperature; incrementing the individual processing station temperature by programmable increments to produce volatile and non-volatile component; and contacting the volatile component directly with aromatization catalyst to produce a first product which on cooling to a temperature of 0-5 degrees C produces second volatile component, first renewable fuel and water; and    (2) converting (III) biomass to renewable fuels: providing the device containing a programmable number of processing stations and a series of catalysts; subjecting lignin-rich biomass within the stations to the programmable starting temperature; incrementing the individual processing station temperature by programmable increments to produce volatile and non-volatile component; and contacting the volatile component with a dehydration catalyst (60) to produce first product which on cooling to 2-20 degrees C produces second volatile component, first renewable fuel (33) and water.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of programmable catalyst chain with three stations.    Renewable fuel (33)    Processing stations (50)    Dehydration catalyst (60)    Aromatization catalyst (61)    Gas-upgrading catalyst (62)
