Fluidized bed reactors for biomass conversion and greenhouse gas mitigation

提出的研究内容涵盖了流化床反应器的基本原理和应用。基础研究将通过研制一种新型的声波悬浮实验装置，重点研究具有相似和不同性质的细粉接触时产生的静电现象。这些发现将被扩展到解释流化床中的颗粒电荷，其中颗粒相互碰撞并与反应器壁碰撞。流化颗粒装药实验将在流化床装置中进行。这项工作是UBC一个全球领先的研究项目的一部分，该项目始于20世纪90年代末，旨在了解流化床反应器和其他颗粒处理系统中颗粒的充电和对流化行为的影响。研究结果将应用于加拿大和国外的聚合物、制药和生物材料加工行业。NSERC发现基金每年将资助一名博士生，为期5年。应用研究将侧重于开发新型微波辅助气体脉动卧式流化床催化反应器的第一个数学模型，该反应器已在我的实验室开发，已获得专利并申请用于将生物质残留物转化为生物燃料和生物炭，这是一种碳负技术，将有助于加拿大工业部门脱碳。该模型将使用中试工厂测试数据进行验证，然后应用于优化操作参数，并协助扩大规模和设计商业反应器，用于催化热解生物质残留物和废塑料，以生产高质量的生物燃料和生物炭产品。作为一个新的生物精炼研究和创新中心（BRIC）的一部分，我们的实验室在加拿大创新基金会（CFI）主要设备拨款的资助下，委托了一个试点反应堆。NSERC发现基金每年将资助一名博士生，为期5年。

The proposed research covers both the fundamentals and applications of fluidized bed reactors.      The fundamental research will focus on understanding the electrostatics phenomena of fine powders, which are generated during contact of particles of similar and dissimilar properties by developing a novel acoustic levitation test apparatus. The findings will be extended to interpret particle charging in fluidized beds where particles are colliding each other and with the reactor walls. The fluidization particle charging experiments will be performed in a fluidized bed unit. This work is part of a globally leading research program at UBC started in late 1990s to understand particle charging and impact on fluidization behaviour in fluidized bed reactors and other particle handling systems. The results will be applied to the polymer, pharmaceutical and biomaterial processing industries in Canada and abroad. The NSERC Discovery grant will support one PhD student each year for 5 years.       The applied research will focus on the development of the first mathematic model for the novel microwave-assisted gas-pulsating horizontal fluidized bed catalytic reactor, which has been developed in my lab, patented and applied for converting biomass residues to biofuels and biochar, which as a carbon negative technology will contribute to decarbonizing Canadian industry sector. The model will be validated using the pilot plant test data and then applied for optimizing the operating parameters and assisting the scale up and design of commercial reactors for catalytic pyrolysis of biomass residues and waste plastics to high quality biofuels and biochar products. A pilot reactor has been commissioned in our lab with funding from a Canada Foundation for Innovation (CFI) major equipment grant, as part of a new Biorefining Research and Innovation Centre (BRIC). The NSERC Discovery grant will support one PhD student each year for 5 years.
