A new generation of zirconia supported metal oxide catalysts for converting low grade renewable feedstocks to biodiesel

► Development of a very active pellet type of ZrO2 catalyst for biodiesel production. ► Durable catalyst by using supported mixed metal oxides on ZrO2. ► Attaining 99% FAME yield by using two-stages packed bed reactors. ► Dependency of the catalytic activity on the supported metal oxides.
