Advances in Biofuels Production Technologies: A review

Abstract

The increasing research and development of biofuels production has dominated spectrum of science and engineering in recent years. In this paper, a review of literature on recent advances in this area of biofuels production technologies, including green diesel synthesis, and other technologies namely; advance biofuels production, process intensification, biorefinery concept and integrated energy system approach are reviewed. The choice of technology largely depends on feedstock nature and composition, targeted biofuels and economics of the production technology. Therefore, challenges associated with feedstock availability has been intensively compiled providing alternative sources like waste, biomass and oils. Challenges associated with technology, profitability and energy density of biofuels and products are highlighted. The conclusion is that, these recent advances provide wider view into production of biofuels and its flexibility in both science and engineering would ensure marketability of biofuels.
