The bioliq® process, developed at the Karlsruhe Institute for Technology, aims at the production of synthetic fuels and chemicals from biomass. The bioliq® 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.

中试规模气流气化炉中生物质燃料炉渣流动性的优化

由卡尔斯鲁厄理工学院开发的 bioliq® 工艺旨在从生物质中生产合成燃料和化学品。bioliq® 技术基于两步法，采用分散热解从残余生物质中生产可运输的泥浆，并使用生物质液化技术对泥浆进行中央气流气化。本研究的重点是在气化过程中通过熔化无机灰分成分形成的炉渣。为了平稳地操作气化器，必须定义所需的粘度范围。基于结构的粘度模型用于预测气化炉出口处炉渣的粘度。对于完全液态渣系统，实验和计算粘度之间实现了良好的一致性。
