The policy of reducing fuel consumption, together with the increasing awareness on environmental concerns, have prompted extensive research worldwide on alternative fuel development, and an improvement in the performance of existing engines. Biofuel production from waste has a promising outlook for this purpose and recent research has shown that catalytic production is the way forward for an efficient production at commercial scales. Current challenges in this respect are efficiency of catalysts for the waste biomass with different level of impurities as well as stability and reusability of catalysts during long process runs while ensuring the desired properties of produced fuel. In this project waste cooking oil with different impurities will be used as a cheap feedstock for the production of biodiesel using novel magnetically separable catalysts. Novel functionalised magnetic nano catalysts will be synthetized and characterised. The efficiency of nano catalysts as well as their stability and their effect on the properties of produced biodiesel via a continuous reaction will be investigated in details. The project will be done in collaboration with industry.
