Te inadequacy of fossil fuel is the main driving force of the future sus-tainable energy around the world. Interest in biodiesel is growing rap-idly worldwide due to energy security, diversity, and sustainability as well as for greenhouse gas mitigation. Since heterogeneous catalysis is used in chemical industry for biodiesel production, achieving optimal catalytic performance is a signi?cant issue for chemical engineers and chemists. Terefore, enormous attention has been placed in recent years on the selection of heterogeneous catalyst in biodiesel industry, where the cata-lyst could be facilitated highly selective toward desired products, easily handled, separated from the reaction medium and subsequently reused. Tis book stresses an overview on the contributions of tailored solid acid and base catalysts to catalytic biodiesel synthesis, and the in?uences of heterogeneous catalyst properties on biodiesel yield in order to develop a better understanding of catalyst design for the green production process as well as practical applications in the biodiesel industry. Coverage also includes the innovative and new techniques of biodiesel production pro-cesses currently used, illustrating the technological options and empha-sizing the limitations factors for each technique, and the best choices available in a manner accessible to a general readership, biochemical engi-neers, academics, professionals, and industrial researchers.
