Method of and apparatus for processing biomass

A method of processing biomass by subjecting, in a digester (100), the biomass to bio-solvent and process control substance, which includes at least one inorganic substance determined as ash for intensifying formation of furfural; and separating furfural from the biomass processed in the digester (1...

More Information
Summary:A method of processing biomass by subjecting, in a digester (100), the biomass to bio-solvent and process control substance, which includes at least one inorganic substance determined as ash for intensifying formation of furfural; and separating furfural from the biomass processed in the digester (100). Menetelmä prosessoida biomassaa altistamalla, keittimessä (100), biomassa bioliuottimelle ja prosessin ohjausaineelle, joka sisältää ainakin yhden epäorgaanisen aineen, joka määritelty tuhkaksi furfuraalin muodostumisen tehostamiseksi; ja erottelemalla furfuraali biomassasta, joka on prosessoitu keittimessä (100).
