BTL laboratory at Mid Sweden University

• This paper presents the BTL (biomass to liquids) laboratory of MIUN (Mid Sweden University) for production of bio-automotive fuels through biomass gasification. The process is intended to be realized in laboratory scale at MIUN with focus on key issues in the BTL technology development. Thus, the BTL laboratory becomes a resource for BTL education, research and development. The BTL laboratory is based on indirect gasification and the gasifier is a combination of a BFB steam gasifier and a CFB combustion riser. The biomass feeding system is unique in application. The syngas is automatically sampled and analyzed on-line on demand. Considering small & medium scale bio-automotive fuel plant, an oxygen plant would be too expensive to be integrated in BTL systems. An indirect gasifier is thus the choice for development to obtain a good quality high energy content synthesis gas. Based on calculation work performed by TPS, the most energy effective gasification technique is indirectly fluidized bed gasification with steam as the gasification agent. Integration of the gasifier and FT/DME/EtOH-reactors will be emphasized and a theoretic BTL model will be developed. The plan is to develop an effective and a reliable BTL technology under 100 MW possible for bio refinery integration.
