Periodic Reporting for period 1 - ZEOBIOCHEM (Advanced Zeolite Catalysis for Sustainable Biorefinery to Produce Value-added Chemicals)
Reporting period: 2019-12-01 to 2023-03-31
In detail, we have established the technical methods to enable the activity functionalisation of hierarchical zeolites (e.g. the control of Si/Al ratios for tuning Brønsted acidity and inclusion of noble metals for multi-functionality) using the post-synthesis microwave (MW) modification and surfactant-templating methods. Based on that, comprehensive characterisation was carried out to establish the synthesis (or modification)-property relation for the tailor-made zeolites. With the new hierarchical zeolites, we have developed many new catalysts (including the structured catalysts based on SiC foams) for the proposed biorefinery cases (such as ethyl lactate synthesis and sugar/biooils upgrading), which were investigated thoroughly. Finally, relevant LCA and TEA studies were performed to analyse the carbon footprints and environmental impacts of these catalytic biorefinery systems, as well as pointing out the relevant 'hot spots' for further optimisation and development and economic benefits/shortcomings.
