摘要：
The bioliq (R) process, developed at the Karlsruhe Institute for Technology, aims at the production of synthetic fuels and chemicals from biomass. The bioliq (R) technology is based on a two-step process with decentral pyrolysis for the production of a transportable slurry from residual biomass and the central entrained-flow gasification of the slurry by using biomass-to-liquid technology. This study is focused on the slag, which is formed by melting the inorganic ash components during gasification. To operate the gasifier smoothly, a range of desired viscosity has to be defined. A structure-based viscosity model was used to predict the viscosity of the slags at the gasifier outlet. A good agreement between experimental and calculated viscosities is achieved for fully liquid slag systems.
