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. ********

这项发现资助申请是为了继续我关于喷流和流化现象的研究计划，以及这些技术在环保工艺、清洁能源生产和工艺强化方面的应用。提出了三个具体项目：(1) 流体动力学研究、计算流体动力学 (CFD) 模拟以及用于高温应用的狭缝矩形喷动床 (SRSB) 的放大，(2) 开发用于同时干燥的紧凑型喷动床反应器、烘焙和粉碎用于木屑颗粒生产的生物质，以及 (3) 在流化床膜反应器 (FBMR) 中通过碳氢化合物的蒸汽重整和原位 CO2 捕获来生产超纯氢气。 **喷动床已被开发用于许多热能过程，例如煤、生物质和黑液的干燥、燃烧和气化。项目（1）将为高温喷射床反应器的运行提供关键信息，并提供创新的放大方法。 2011年，加拿大生产了约200万吨木屑颗粒，大部分出口到欧洲、美国和日本，用于供暖和发电。 然而，致命的废气（CO、CH4、CO2）和木颗粒在储存过程中的自热对长途运输造成严重的健康和火灾危害。项目（2）将开发一种紧凑、节能的反应器，用于生产烘焙生物质，其生物活性大大降低，净热值增加，用于制造可安全进行海洋运输的木质颗粒。氢被认为是未来的主要能源载体，其实施可以帮助缓解由于使用化石燃料导致的温室气体排放而导致的全球变暖。项目（3）将开发一种强化工艺，生产用于燃料电池的超纯氢气以及适合封存的高纯度二氧化碳流。这些项目将为未来五年培养2名博士生、2名硕士生和5名本科生，他们具有较高的研究能力，可以在工业界或学术环境中就业。 ******
