The main objective for this thesis was to develop a self selection torrefaction system based on an integrated torrefaction and ball milling reactor system. A lab scale torrefaction system has been developed in order to heat biomass material to a temperature of 260-280°C in an inert environment. This process of torrefaction, or mild pyrolysis, is used to break down hemicellulosic …
