NOVELTY - A biofuel production system (100) comprises a catalytic vapor phase reactor (VPR) (102); a pyrolysis reactor (104) operatively connected to the catalytic VPR; a quench system (106) operatively connected to the catalytic VPR; a water gas shift reactor (108) operatively connected to the quench system; and a hydrotreatment system (110) operatively connected to the quench system.    USE - As biofuel production system for catalytic pyrolysis of biomass (claimed).    ADVANTAGE - The biofuel production system is configured for continuous mode operation or batch mode operation; is suitable to operate using air at atmospheric pressure for catalyst regeneration; and is suitable for catalyst regeneration without using gases with reduced oxygen content compared to air. The process provides high yields of condensable organics which can be used as liquid fuels.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) catalytic pyrolysis of biomass, involving drying a biomass; pyrolyzing the biomass to create a pyrolysis vapor; removing at least one of a char and an ash from the pyrolysis vapor; upgrading the pyrolysis vapor by vapor phase catalysis to produce an upgraded pyrolysis vapor; and condensing a bio-oil from the upgraded pyrolysis vapor; and    (2) a catalytic vapor phase reactor apparatus either comprising a gas-solid catalytic reactor, a feeding auger, a return auger, a hot blower, a first blower, a second blower, a first cyclone, a second cyclone, a third cyclone, a split connection, a dip leg pipe operatively coupled to the split connection, a fluidized bed reactor, a bypass connection and a catalyst feeding vessel, where the feeding auger and the return auger are operatively connected to the gas-solid catalytic reactor and the fluidized bed reactor; the first cyclone and the second cyclone are operatively connected to the gas-solid catalytic reactor; and the third cyclone is operatively connected to the fluidized bed reactor, the first blower, and the second blower; or a housing comprising an auger device, a catalyst inlet, a catalyst outlet, a pyrolysis vapor inlet and a pyrolysis vapor outlet, where the auger device is configured to transport a solid catalyst through at least a portion of the housing; and the housing is configured to permit a pyrolysis vapor to flow through at least a portion of the housing and come into contact with the solid catalyst.
