Abstract

A biomass pyrolysis process in which biomass feedstock particles (having a d5o mean particle size of at least 1 mm) are thermally treated substantially in the absence of oxygen to pyrolyse the biomass feedstock particles. The thermal treatment of the biomass feedstock particles includes a heat treatment drying step at a temperature in the range 100 DEG C to 250 DEG C. Then, at a pre-pyrolysis heating location in a heat treatment system, the biomass feedstock particles are heated to a temperature in the range 280 DEG C to 350 DEG C, held within the same temperature range for a time of at least 5 seconds and then moved from the pre-pyrolysis heating location to a pyrolysis heating location by a conveyor system for heating to a temperature above 350 DEG C for pyrolysis.
