Three-phase catalytic hydrogenation is one of the most environmentally acceptable reaction routes for numerous applications in the petrochemical, fine chemicals and food industries. To achieve higher product yields and minimize production costs and safety concerns, nano-, micro- and macro-levels of the catalyst design must be considered in an integrated approach in relation to the reactor design. The project objectives are: i) to develop catalytically active nanostructures with predominant exposure of active sites possessing high hydrogenation activity and selectivity (>95%) without the use of hazardous poisons; ii) to produce stable arranged catalysts consisting of the developed nanostructures and arranged supports providing optimal reaction conditions for the best catalyst performance; iii) to design a structured semi-batch reactor with embedded arranged catalyst. The novelty is in establishing a structure-reactivity relationship for a structure-sensitive hydrogenation and in designing a novel structured semi-batch reactor. The project's success will lead to knowledge advancement in the field of structure-sensitive reaction fundamentals and in the area of bridging the materials gap between real catalysts and ideal systems. In the future, such catalysts with the active surface approaching model systems should replace multipurpose conventional catalysts for high value products with low output. The practical significance is that the main project deliverable will be a semi-batch structured reactor for multiphase hydrogenations in fine chemicals production. The long-term objective is to actively contribute to the early success of implementation of three-phase catalytic structured reactors in Canada and worldwide. It is believed the research results and highly qualified personnel training in this area will enable the uptake of such perspective catalytic technologies on an industrial scale.

三相催化加氢是最环保的反应路线之一，在石油化工、精细化工和食品工业中有着广泛的应用。为了获得更高的产品产量，并将生产成本和安全问题降至最低，必须将催化剂设计的纳米、微观和宏观层面与反应器设计结合起来考虑。 该项目的目标是： I)开发具有催化活性的纳米结构，其活性中心主要暴露在具有高加氢活性和选择性(&gt；95%)且不使用危险毒物的情况下； Ii)制备稳定的由所开发的纳米结构和有序载体组成的有序催化剂，为获得最佳的催化剂性能提供最佳的反应条件； 3)设计了埋置催化剂的结构化半间歇反应器。 其创新之处在于为结构敏感的加氢反应建立了结构-反应性关系，并设计了一种新型的结构化半间歇反应器。该项目的成功将促进结构敏感反应基础领域的知识进步，以及弥合真实催化剂和理想体系之间的材料鸿沟。在未来，这种具有活性表面逼近模型体系的催化剂将取代多用途的常规催化剂，用于生产高附加值、低产量的产品。其实际意义是，主要项目成果将是用于精细化学品生产中多相加氢的半间歇结构化反应器。长期目标是积极促进在加拿大和全世界早日成功地实施三相催化结构反应器。相信这一领域的研究成果和高素质的人员培训将使这种有远见的催化技术能够在工业规模上采用。
