Chemical Process Engineering
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

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.

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.

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

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.

Mixed alchohols
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

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.
