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.

该参与项目的目的是促进与我们的合作伙伴Enerkem化学和工业应用的新型多层生产者的设计和生产。 Enerkem使用高压力的氢化和通过高压下催化剂上的乙烯氢甲酰化来使用高度选择性的催化剂来构成氧化化合物。 RH/SIO2催化剂（包括其尺寸）的修饰对CO氢化高压具有很大的影响。异源催化剂的高性能归因于Ahigh配体浓度和柔性聚合物框架的结合。该项目的目的是确定几种RH催化剂的生产物，包括其表面尺寸，形态以及它们的氧化状态。这种合作将导致为FutureMarkets的制造和开发更合适的产品。
