Abstract
Biodiesel is a promising clean energy supply that can be made from sustainable and low-grade fuels using a variety of methods. Transesterification is one of the processes that can occur in the manifestation of an effective catalyst. The catalyst may be homogeneous or heterogeneous in nature. This article reviews on the formation of biodiesel from various sources of waste oils using heterogeneous nanocatalysts. The manufacture of biodiesel using homogeneous and heterogeneous catalysis had been extensively studied, and new heterogeneous catalysts are constantly being examined. In general, homogeneous catalysts are effective at remodeling biodiesel with low free fatty acid (FFA) and single-origin feedstock having water. Heterogeneous catalysts, instead have higher interest, a wider scope of selectivity, better FFA, and better water adaptability. These properties are regulated by the number and intensity of active basic or acid sites. In order to achieve a viable alternative to conventional homogeneous catalysts for biodiesel processing, heterogeneous catalysts made from waste and biocatalysts are needed. Nanocatalysts have recently attracted interest due to their high catalytic performance under favorable operating conditions. This review evaluates the usage of heterogeneous nanocatalysts for the production of biodiesel from different sources of waste oil and the factors effecting the process of biodiesel production.
