The gasification of biomass wastes represents a major thermochemical route to produce a high energy value syngas from a source which is renewable and CO2-neutral. However, one of the major issues in the gasification process is contamination of the product syngas with tar. Tar is the key problem for biomass gasification and is a complex mixture of condensable hydrocarbons. The formation of tar causes major process and syngas end-use problems, including tar blockages, plugging and corrosion in downstream fuel lines, filters, engine nozzles and turbines. This proposal seeks to develop a novel gas cleaning process based on low temperature plasma/catalytic technology to produce a clean, high quality syngas from the gasification of waste biomass. Gasification of the biomass will be investigated in an existing small-pilot scale fluidised bed gasifier, modified to include a downstream plasma/catalytic syngas cleaning process. Experimental and detailed analytical work developing the coupled biomass gasification-gas cleaning process will enable a mechanistic understanding of the tar reduction process and will be extended by CFD modelling of model tar compounds. Process modelling and simulation of the combined biomass gasification-plasma/catalytic gas clean-up sytem will build a foundation for process analysis, optimal design and operation to facilitate exploitation of this innovative technology development.

生物质废物的气化是从可再生且二氧化碳中性的来源生产高能源价值合成气的主要热化学途径。然而，气化过程中的主要问题之一是产品合成气被焦油污染。焦油是生物质气化的关键问题，是可凝性碳氢化合物的复杂混合物。焦油的形成会导致主要的工艺和合成气最终使用问题，包括下游燃料管线、过滤器、发动机喷嘴和涡轮机中的焦油堵塞、堵塞和腐蚀。该提案旨在开发一种基于低温等离子体/催化技术的新型气体净化工艺，通过废弃生物质气化生产清洁、高质量的合成气。生物质的气化将在现有的小型中试规模流化床气化炉中进行研究，并进行修改以包括下游等离子体/催化合成气清洁工艺。开发生物质气化-气体净化耦合工艺的实验和详细分析工作将使焦油还原过程的机械理解成为可能，并将通过模型焦油化合物的 CFD 建模进行扩展。生物质气化-等离子体/催化气体净化系统组合的过程建模和模拟将为过程分析、优化设计和操作奠定基础，以促进这一创新技术的开发。
