  3. Working groupSynthetic Biofuels • The main R&D work within this group focuses on production • of synthetic biofuels from lignocellulosic biomass e.g.: • Fischer TropschDiesel • BioSNG • Mixed Alcohols • Hydrogen

  4. Fischer Tropsch Diesel Synthetic fuel or synfuel is a liquid fuel obtained from coal, natural gas, oil shale or biomass. Biomass is gasified in a gasifier, the product gas is cleaned up and via Fischer Tropsch conversion, diesel fuel (biodiesel) is produced.

  5. Fischer Tropschsynthesis The Fischer–Tropsch synthesis is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen into liquid hydrocarbons. • Process conditions: • Temperature range 150-300°C (normally low to middle part of the range) • Pressures range from one to several tens of atmospheres • A variety of synthesis-gas compositions can be used • For cobalt-based catalysts the optimal H2:CO ratio • is around 1.8–2.1 • Iron-based catalysts promote the water-gas-shift • reaction and thus can tolerate lower ratios.

  6. Fischer Tropsch Diesel • Fischer Tropsch synthesis (FT) to produce Diesel from wood • Pilot plant designed, erected and optimised • capacity of 5kg/day FT products • As FT reactor here a slurry reactor is used, as it has several advantages compared to other technologies. • The main R&D work: • optimisation of the gas treatment • testing of different FT catalysts • Figure: FICFB gasification plant with F-T pilot plant in Güssing

  7. BioSNG • Bio Synthetic Natural Gas • The first experiments in 1997 at the 100kW gasifier at the Institute of Chemical Engineering Vienna University of Technology. • In 2003 the EC-project BioSNG started, where a 1MW (100Nm³/h BioSNG) demonstration plant was erected and operated. Within this project the whole chain from wood chips to usage of the BioSNG in a car was successfully demonstrated. The actual work here is to tests different sulphur resistant catalysts, to simplify the gas treatment.

  8. Mixed alchohols Mixed alcohols from biomass steam gasification • Advantages: • the gas cleaning is much simpler (as the catalyst is resistant against sulphur poisoning) • produced mixed alcohols can easily be converted over dehydration and oligomerisation to high quality fuels • this pathway seem to be a promising method to produce transportation fuels from renewables at low costs • Aim of the project: • to investigate the synthesis of mixed alcohols in laboratory scale • economic calculation of the production costs

  9. BioH2 4Refineries BioH2 4Refineries Hydrogen Production for Refineries Based on Biomass Steam Gasification The results have been achieved in cooperation with the experts of process simulation as a part of the zero emisson technologies team.

  10. IEA Bioenergy Task 33 „Thermal GasificationofBiomass“ The objectives of Task 33 are to monitor, review, and exchange information on biomass gasification research, development, and demonstration and to promote cooperation between the participating countries and industry to eliminate technological impediments to the thermal gasification of biomass. The ultimate objective is to promote commercialization of efficient, economical, and environmentally preferable biomass gasification processes, for the production of electricity, heat and steam; for the production of synthesis gas for subsequent conversion to chemicals, fertilizers, hydrogen and transportation fuels, and also for co-production of these products. www.ieatask33.org
