To optimize different kind of novel zeolites and mesoporous silica in order to maximize the selectivity, activity and stability for a reaction such as dimerization/oligomerization, metathesis or cracking of hydrocarbons. In addition, to investigate several transition metals (e.g. Zr, Ti, Ni) and their effect on the catalyst performance. Finally, to study different impurities (e.g. oxygen, CO2) in order to develop a robust catalyst that withstand harsh conditions in the industry.
