Investigation of the oxidation state of rhodium based catalysts for heterogeneous hydroformylation reactions

该Engage项目的目标是促进我们的合作伙伴Enerkem设计和生产用于化工和工业应用的新型聚苯乙烯。Enerkem使用选择性很高的催化剂，在高压下通过CO加氢和乙烯氢甲酰化反应生成氧化化合物。Rh/SiO_2催化剂的改性，包括催化剂的尺寸，对CO高压加氢有很大的影响。多相催化剂的高性能归功于高配体浓度和灵活的聚合物骨架的结合。该项目的目标是确定几种Rh催化剂的性质，包括它们的表面尺寸、形貌以及它们的氧化状态。这一合作将导致制造和开发更适合未来市场的产品。

The goal of this Engage project is to facilitate the design and production of novel polystyrenes for chemical andindustrial applications of our partner, Enerkem. The Enerkem uses highly selective catalysts to formoxygenated compounds by CO hydrogenation and by ethylene hydroformylation over catalysts under highpressure. Modifications of the Rh/SiO2 catalyst, including its size, have a great influence on CO hydrogenationat high pressure. The high performance of the heterogenous catalysts has been attributed to a combination of ahigh ligand concentration and a flexible polymer framework. The objective of the project is to determine theproperties of several Rh catalysts, including their surface size, morphology, as well as their oxidation state.This collaboration will lead to the manufacturing and development of more appropriate products for futuremarkets.
