BIO2C - Torrefaction Pilot Plant
CENER - BIO2C
The National Renewable Energy Centre of Spain (CENER) develops applied research in renewable energies, and provides technological support to companies and energy institutions in six areas: wind, solar thermal and photovoltaic solar energy, biomass, smart and efficient buildings and districts, and grid integration of energy. CENER is a technology centre with worldwide recognised prestige, activity and experience. CENER’s headquarters is located close to Pamplona (Navarre-Spain). The centre has also cutting edge techonolgical infrastructures and offices at other locations. CENER´s expertise is focused on three main areas: Development of R+D+i projects for industrial application. Highly skilled testing services and certification for components. Technical assistance and feasibility studies for renewable energy technologies. CENER’s activity covers the entire renewable energy generation process: Renewable Resource Assesment. Development of Simulation and Design Tools. Development of Renewable Energy Generation Technology. Definition and Performance of Tests on complete systems and components. Technological Risk Assessment. Feasibility Studies. Development and Application of Regulatory Laws. CENER Biomass Department / BIO2C CENER Biomass Department performs applied research activities in the field of biomass providing R&D services and technical assitanceto all agents of the sector. The main infrastructures in thisdepartment include the Biomass Laboratory (biomass & biofuels characterization and process development at lab scale), as well as the Biorefinery and Bioenergy Centre (BIO2C). The Biorefinery and Bioenergy Centre (BIO2C) is a semi-industrial pilot scale test facility able to develop production processes for bioproducts, solid biofuels, advanced liquid or gaseous biofuels, as well as biorefinery concepts integrating different valorization routes, as an intermediate step between laboratory and the industrial scale-up of these technologies. BIO2C constitutes an integrated trial and demonstration platform designed to develop processes, equipment and specific, components, new bio-products or biofuels and bio-refinery concepts.

Additional Technical Information:
Development and application of torrefaction treatment on a broad range of materials, the pilot plant is very flexible regarding feedstock bulk density and particle size being able to process difficult fuels with very low bulk density and very high fines content: :
Herbaceous: cereal straw
Woody: pine, poplar, beech, eucalyptus, pawlonia, olive tree pruning , etc.
Variety of organic wastes, including low density materials and materials with high content of fines and dust.
The torrefaction pilot plant (150 - 350 kg/h) consists of a rotary reactor with internal elements designed to achieve a good flow of biomass particles, to improve homogenization and to assure good heat transfer conditions inside it. Reactor heating is carried out externally through the wall and internally using thermal oil (250-300ºC) as heat transfer fluid. Pre-dried and crushed biomass is fed from one side of the reactor and flows to the other side while is heated up to temperatures in the range 240-310ºC to convert raw feedstock into thermally treated product.
The plant is very flexible regarding raw material particle size distribution (0,25-40 mm) and bulk density (50-500 kg/m3) including agricultural biomass like straw. It performs excellent mixing and agitation minimizing internal temperature gradients, easy temperature control, being able to cope with feedstock with exothermal heat of reaction, producing an extremely homogeneous product.
Combustible gases from the reaction are burned in a thermal oxidiser. Condensable compounds are sampled with an off-line sampling with water impingers in cold water. Water vapour content is quantified gravimetrically from the total condensate amount. The sample is characterized by a combination of chromatographic technics (HPLC-DAD, HPLC-RID, GC-FID y GC/MS). Non-condensable fraction is sampled in a gas bag and characterized by micro GC-TCD.
