The overarching aim of his research is to enable a transition from fossil to renewable feedstocks in the chemical and petrochemical industry. This research is performed on multiple levels of detail. Firstly, new and intelligent process pathways for renewable feedstocks are enabled using technology development. The purpose of the processing is to introduce the products into existing material streams in the chemical industry. The focal point of the technological development is in heterogeneous catalysis, but also non-catalytic processes and gas cleaning methods have been developed.
