It is a biodegradable renewable fuel. Its production is growing exponentially due to greater concerns about environmental protection and depletion of fossil fuel resources. Further, its production from non-edible oils and animal fat is more desirable than from edible oils due to lower cost of non-edible feedstocks and elimination of food verses fuel issues. Solid acid catalysts are ideal for conversion of such low-grade oils to biodiesel. Biodiesel from non-edible oils can be produced by two methods: (1) simultaneous esterification of fatty acids and transesterification of fatty acid glycerides and (2) hydrolysis of glycerides followed by esterification. This account reports the catalytic performance of solid, Fe-Zn double-metal cyanide (DMC) complexes and other acid catalysts in these transformations for biodiesel production. The factors influencing the catalytic performance of the solid acid catalysts in biodiesel production are discussed.</p>10aBiodiesel10aDouble-metal cyanide10aEsterification10aHydrolysis10asolid acid catalysts10atransesterification1 aSrinivas, Darbha1 aSatyarthi, Jitendra, K.  uhttps://library.ncl.res.in/content/biodiesel-production-vegetable-oils-and-animal-fat-over-solid-acid-double-metal-cyanide-0
