The bioliq® Entrained-Flow Gasifier – A Model for the German Energiewende

Abstract

The bioliq® process was developed at the Karlsruhe Institute of Technology (KIT) for the production of synthetic fuels from dry biomass residues. Biofuels of high quality are produced sustainably in various process steps. This multistage process not only considers the necessity for decentralized supply of the biomass, but also the necessity for a large centralized fuel synthesis that benefits from economy of scale. The entire process chain of pyrolysis, gasification, gas cleaning, and synthesis is operated on a pilot scale at KIT. The high-pressure entrained-flow gasifier converts the biomass, pretreated in a fast pyrolysis step, into a synthesis gas for the production of gasoline in the subsequent synthesis step. The first experimental results from the pilot plant are presented in this paper.
