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.
