Chemical reaction engineering plays a significant role in advancing the conceptualization of environmentally friendly chemical processes. The long-term objective of the proposed research is to develop novel catalysts, mechanistically based rate models and innovative chemical reactors in order to facilitate a number of environmentally friendly industrial processes. To accomplish this task the proposed research will take advantage of the applicant's previous patented technology such as the CREC Riser Simulator and bench scale photocatalytic reactors. These are unique devices for establishing both the catalyst performance and the kinetic rate models under industrial conditions. These studies will be developed using statistically based kinetic model discrimination and parameter estimation and will lead to rate equations incorporating intrinsic kinetics, adsorption and intraparticle diffusion. The specific areas for this research can be summarized as follows: a) Catalytic conversion of biomass using a fluidizable nickel based catalyst; b) Chemical looping for the reduction of CO2 emissions employing a novel oxygen carrier;c) Catalytic gasoline desulfurization via "dehydrosulfidation";d) Photocatalytic conversion of organic pollutants in water, doping the photocatalyst with iron cations. The proposed research will help bring into practice chemical technologies which will provide the following benefits: a) Reduction of CO2 emissions, b) Production of energy from biomass with zero net CO2 emissions, c) Production of green fuels with lower levels of sulfur containing compounds, d) Removal of organic pollutants from water. As a result, this research will substantially contribute to the protection of the environment and the well being of the Canadian population, being well in line with the two areas of priority set by NSERC for the funding reallocation exercise: a) application of new technologies in Canadian resource industries, b) research in sustainable emerging technologies.

化学反应工程在推进环境友好化学过程的概念化方面起着重要作用。拟议研究的长期目标是开发新型催化剂，基于机械的速率模型和创新的化学反应器，以促进一些环境友好的工业过程。为了完成这项任务，拟议的研究将利用申请人以前的专利技术，如CREC上升模拟器和实验室规模的光催化反应器。这些是用于在工业条件下建立催化剂性能和动力学速率模型的独特装置。这些研究将开发使用统计为基础的动力学模型的歧视和参数估计，并将导致速率方程纳入本征动力学，吸附和颗粒内扩散。本研究的具体领域可以概括如下：a）使用可流化的镍基催化剂催化转化生物质; B）使用新型氧载体减少CO2排放的化学循环;c）通过“脱氢硫化”催化汽油脱硫;d）用铁阳离子掺杂光催化剂，光催化转化水中的有机污染物。拟议的研究将有助于将化学技术付诸实践，这些技术将提供以下好处：a）减少二氧化碳排放，B）从生物质生产能源，净二氧化碳排放为零，c）生产含硫化合物水平较低的绿色燃料，d）去除水中的有机污染物。因此，这项研究将为环境保护和加拿大人民的福祉做出重大贡献，完全符合NSERC为资金重新分配工作设定的两个优先领域：a）加拿大资源行业新技术的应用，B）可持续新兴技术的研究。
