This Discovery Grant application is to continue my research program on spouting and fluidization phenomena, and the application of these technologies to environmentally friendly processes, clean energy production, and process intensification. Three specific projects are proposed: (1) Hydrodynamic studies, computational fluid dynamics (CFD) simulation, and scale-up of slot rectangular spouted beds (SRSB) for high temperature applications, (2) Development of a compact spouted bed reactor for simultaneous drying, torrefaction and comminution of biomass for wood pellet production, and (3) Production of ultra-pure hydrogen in a fluidized bed membrane reactor (FBMR) by steam reforming of hydrocarbon with in-situ CO2 capture. **Spouted beds have been developed for many thermal energy processes, such as drying, combustion, and gasification of coal, biomass, and black liquor. Project (1) will provide critical information for operation of a high-temperature spouted bed reactor, and an innovative approach for scale-up. In 2011, Canada produced about 2 million tonnes of wood pellets, mostly exported to Europe, USA and Japan for heating and power generation. However, deadly off-gassing (CO, CH4, CO2) and self-heating of wood pellets during storage pose serious health and fire hazards for long-distance transportation. Project (2) will develop a compact and energy-efficient reactor for producing torrefied biomass, with strongly reduced biological activity, and increased net calorific value, for making wood pellets which are safe for ocean transportation. Hydrogen is foreseen as a major future energy carrier, whose implementation could help to mitigate global warming due to greenhouse gas emissions from use of fossil fuels. Project (3) will develop an intensified process for producing ultra-pure hydrogen for fuel cells as well as a high-purity stream of CO2 suitable for sequestration. These projects will train 2 PhD, 2 Master's and 5 undergraduate students with high research ability for careers in industry or an academic environment for the next five years. ********

这项发现赠款的应用程序是继续我关于喷口和流化现象的研究计划，并将这些技术应用于环保的过程，清洁能源生产和过程强化。提出了三个特定项目：（1）用于高温应用的水矩形喷出床（SRSB）的水体动力学研究，计算流体动力学（CFD）模拟以及狭缝矩形喷出床（SRSB）的规模，（2）开发紧凑型喷孔式床反应堆，用于同时干燥，摩尔液生产和木质生产，并在木质生产中进行流动性生产，并（3）pellet和3）膜反应器（FBMR）通过蒸汽重整碳氢化合物的蒸汽改革，其原位二氧化碳捕获。 **已经开发了针对许多热能过程的喷嘴床，例如干燥，燃烧和煤，生物量和黑酒的气化。项目（1）将为高温喷口床反应堆的运行提供关键信息，以及用于扩大规模的创新方法。 2011年，加拿大生产了约200万吨木材颗粒，主要出口到欧洲，美国和日本进行供暖和发电。 然而，致命的瓦解（CO，CH4，CO2）和储存过程中木材颗粒的自加热构成严重的健康和火灾危害，以进行长途运输。项目（2）将开发一种紧凑而节能的反应堆，用于产生摩托车，生物量强烈降低，并增加净热量，以使木材颗粒使海洋运输安全。氢被预见是主要的未来能源载体，由于使用化石燃料的温室气体排放，其实施可能有助于减轻全球变暖。项目（3）将开发出一种加强的过程，用于为燃料电池生产超纯净的氢以及适合隔离的高纯度二氧化碳流。这些项目将在未来五年内培训2位博士学位，2位硕士和5名本科生，具有高度研究职业或学术环境的研究能力。 ********
