Reinhard Rauch Achema 2012 Institute of Chemical Engineering page 1 Chemical Process Engineering Working group Synthetic Biofuels Content •Working group Synthetic Biofuels •R&D Projects •Links and Contact Achema 2012 Institute of Chemical Engineering page 2 Chemical Process Engineering Working group Synthetic Biofuels The main R&D work within this group focuses on production of synthetic biofuels from lignocellulosic biomass e.g.: •Fischer Tropsch Diesel •BioSNG •Mixed Alcohols •Hydrogen Achema 2012 Institute of Chemical Engineering page 3 Chemical Process Engineering 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. Achema 2012 Institute of Chemical Engineering page 4 Chemical Process Engineering Fischer Tropsch synthesis 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. Achema 2012 Institute of Chemical Engineering page 5 Chemical Process Engineering 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 Achema 2012 Institute of Chemical Engineering page 6 Chemical Process Engineering 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. Achema 2012 Institute of Chemical Engineering page 7 Chemical Process Engineering 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 Achema 2012 Institute of Chemical Engineering page 8 Chemical Process Engineering 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. Achema 2012 Institute of Chemical Engineering page 9 Chemical Process Engineering IEA Bioenergy Task 33 „Thermal Gasification of Biomass“ 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 Achema 2012 Institute of Chemical Engineering page 10 Chemical Process Engineering IEA Bioenergy Task 33 „Thermal Gasification of Biomass“ Biomass gasification facilities database www.ieatask33.org Achema 2012 Institute of Chemical Engineering page 11 Chemical Process Engineering Further information Links: http://www.vt.tuwien.ac.at http://www.vt.tuwien.ac.at/chemical_process_engineering_and_energy_tec hnology/synthetic_biofuels/EN/ www.ieatask33.org www.bioenergy2020.eu Contact: Dr. Reinhard Rauch Email: [email protected] Tel.: +43 1 58801 166303 FAX: +43 1 58801 16699 Achema 2012 Institute of Chemical Engineering page 12
