CENER Biomass Pre-Treatment Unit

CENER (National Renewable Energy Centre of Spain) operates the Pre-treatment Unit integrated in its Biorefinery and Bioenergy Centre (BIO2C) for production of batches of pre-treated biomass. A pilot plant with a production capacity of 150-350 kg/h including chipping, chopping, drying, thermal treatment, and pelletization. The thermal treatment unit consists of an indirectly heated cylindrical reactor using thermal fluid at temperatures between 220 and 300 ºC to convert raw biomass into thermally treated product. Combustible gases from the reaction are burned in a thermal oxidiser. The pilot plant is very flexible regarding bulk density and particle size, being able to process difficult fuels with very low bulk density and very high fines content. More info:
