Simple Synthesis of Novel Cr-EDTA-MOF: A Green, Reusable, and Versatile Catalyst for the Production of Biodiesel Fuel from Oleic Acid and Palmitic Acid

“…Reduction in fuel reserves and rising environmental issues have increased the attention of researchers toward alternative fuels in place of conventional fuels. , To protect the environment, the search for green fuels to replace fossil fuels is necessary. , Biodiesel (the most attractive biofuel type) is the most potential alternative fuel for conventional diesel engines . Biodiesel can be used as a green fuel in engines in pure form or mixed with diesel in different ratios in compression combustion engines. , Transesterification of pure triglycerides, which are mainly found in expensive feedstocks such as vegetable oils, has been one of the most useful and widely used methods to produce biodiesel based on free fatty acids. − In recent years, many countries have emphasized and encouraged the use of alternative green fuels such as biodiesel fuel by governmental pathways by means of both incentives and prescriptive volumetric necessities . Biodiesel has been generally regarded as the most promising alternative fuel in comparison to petroleum-based diesel owing to its nontoxic, − sulfur-free, and biodegradable .…”
