NOVELTY - A biomass conversion system consists of a catalytic pyrolysis subsystem, a butanol reactor system, a microorganism growth system including a microorganism growth apparatus, and a butanol separation system. The catalytic pyrolysis subsystem is operatively connected to the butanol reactor system. The butanol reactor system is operatively connected to the microorganism growth system, and the butanol separation system.    USE - Biomass conversion system is used in large-scale production of biofuel product, batch production of biofuel product and continuous production of biofuel product (all claimed).    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) catalytic pyrolysis system, which consists of a catalytic pyrolysis reactor for pyrolyzing biomass to produce synthesis gas, bio oil, char, hydrocarbonaceous substance (CnHm), carbon dioxide and/or carbon monoxide, and a water-gas shift reactor arranged to intake carbon monoxide and produce carbon dioxide and hydrogen, and/or a char gasifier/re former arranged to intake char and gasify the char to produce hydrogen;    (2) hollow fiber membrane bioreactor (3000), which consists of a cartridge (3002) including carbon dioxide hollow fiber (3004), a hydrogen hollow fiber (3006) and a biofilm (3008), a hydrogen gas inlet (3010), a carbon dioxide gas inlet (3012), an air-sparged media inlet (3014), a port (3015), a media outlet (3016), a hydrogen gas outlet (3016), and a carbon dioxide gas outlet (3020); and    (3) method for converting biomass, which involves pyrolyzing biomass to produce synthesis gas, bio oil, char, hydrocarbonaceous substance (CnHm), carbon dioxide and/or carbon monoxide, and producing carbon dioxide or hydrogen from carbon monoxide in a water-gas shift reaction, or hydrogen from char in char gasifier/reformer.
