Personal profile
Research Interests
Identifying the optimum thermochemical route (gasification, pyrolysis), and; chemical hydrolysis route for the production of chemicals and second generation transport fuel from biomass and; waste. Using laboratory and; pilot scale processing facilities to test and; optimise the yield of selected product from characterised feedstocks. The goal will be to develop novelty through optimising the process variables for particular feedstocks or products.Develop and test catalysts/chemical processes for the production of and upgrading bio-oil.Develop state of the art pre-treatment processes, that will enable rapid and environmentally benign procedures for hydrolysis of the carbohydrate components in lignocellulosic materials. Demonstrate the feasibility of producing bio syngas and develop and test catalysts/chemical processes for production of alcohol or diesel fuels
Biography
Prof J J Leahy is currently an associate professor in the Dept of Chemical Sciences at the University of Limerick where he is involved in teaching, curriculum development and research in the area of waste management and renewable energy. He currently heads a research group consisting of chemists and chemical engineers that is focused on chemical technologies for biofuels and biorefining from wastes with particular interests in :
