Problem statement

The biorefinery approach uses farm residues to produce bio-materials and energy, without competing with food production.

Executive summary

The lignocellulosic biomass residues used do not compete with food and feed production, but have to be collected from wide‐spread areas for industrial large‐scale use. The two‐stage gasification concept bioliq offers a solution to this problem. It aims at the conversion of low‐grade residual biomass from agriculture and forestry into synthetic fuels and chemicals. Central element of the bioliq process development is the 2–5 MW pilot plant along the complete process chain: fast pyrolysis for pretreatment of biomass to obtain an energy dense, liquid intermediate fuel, high‐pressure entrained flow gasification providing low methane synthesis gas free of tar, hot synthesis gas cleaning to separate acid gases, and contaminants as well as methanol/dimethyl ether and subsequent following gasoline synthesis.

Technology description

bioliq® is one answer searching for high quality BTL fuels or fuel components produced from sustainable biomass residuals. The problem to be solved is the widely distributed rising of biomass connected to the need of large scale fuel production plants required by economies of scale. The solution is the de-centralized pre-treatment of biomass to obtain an intermediate energy carrier of high energy density (bioliqSyncrude), which can be transported economically over long distances to supply an industrial plant of reasonable size for synthetic fuel production. By chemical synthesis fuels will be produced which can be used as drop-in fuels or as stand-alone products completely compatible to exiting diesel or gasoline type fuels. Nearly any type of dry biomass can be utilized for this process; a focus is set on by-products and residues of agriculture, forestry or landscaping.

Market deployment considerations

KIT works on the bioliq process development for synthetic fuels production with partners from industry. The bioliq pilot plant aims at process demonstration and research platform.

Environmental considerations

The bioliq process is estimated to perform around 85 % GHG reduction, LCA available from verious projects
