成果简介	NOVELTY - Producing biodiesel from Cynodon dactylon(Bermuda grass) involves (a) harvesting and drying Bermuda grass to reduce moisture content; (b) grinding the dried Bermuda grass biomass to increase surface area for lipid extraction; (c) extracting lipids from biomass using a Soxhlet extraction method with an organic solvent selected from methanol, ethanol, and chloroform; (d) removing volatile solvents from the lipid extract using rotary evaporation to concentrate the lipids; (e) conducting transesterification by reacting the lipid extract with methanol in the presence of potassium hydroxide as catalyst, at 55-60 ℃ and an alcohol-to-oil molar ratio of 3:1; (f) separating resulting biodiesel (fatty acid methyl esters, FAME) from glycerol by gravitational separation in a separating funnel; (g) washing the biodiesel with water to remove residual methanol and impurities; (h) drying the biodiesel to remove residual water; (i) collecting the final biodiesel product. USE - Method for producing biodiesel from Cynodon dactylon(Bermuda grass). ADVANTAGE - The method enables offering an efficient, sustainable, and cost-effective approach to biodiesel production, utilizing a non-food biomass and addressing challenges such as feedstock competition and resource scarcity, enhancing fuel quality. DETAILED DESCRIPTION - Producing biodiesel from Cynodon dactylon(Bermuda grass) involves (a) harvesting and drying Bermuda grass to reduce moisture content; (b) grinding the dried Bermuda grass biomass to increase surface area for lipid extraction; (c) extracting lipids from biomass using a Soxhlet extraction method with an organic solvent selected from methanol, ethanol, and chloroform; (d) removing volatile solvents from the lipid extract using rotary evaporation to concentrate the lipids; (e) conducting transesterification by reacting the lipid extract with methanol in the presence of potassium hydroxide as catalyst, at 55-60 ℃ and an alcohol-to-oil molar ratio of 3:1; (f) separating the resulting biodiesel (fatty acid methyl esters, FAME) from glycerol by gravitational separation in a separating funnel; (g) washing the biodiesel with water to remove residual methanol and impurities; (h) drying the biodiesel to remove residual water; (i) collecting the final biodiesel product, where the biodiesel meets industry standards for fuel quality and performance. An INDEPENDENT CLAIM is included for a method for optimizing the production of biodiesel from Cynodon dactylon(Bermuda grass) by improving the transesterification process, which involves: (1) preparing Bermuda grass by harvesting, drying, and grinding the biomass to a fine powder; (2) extracting lipids from the ground Bermuda grass using Soxhlet extraction with a solvent mixture of methanol and chloroform; (3) concentrating the lipid extract by removing the solvents via rotary evaporation; (4) conducting transesterification of the lipid extract by reacting the lipids with methanol in the presence of potassium hydroxide as a catalyst; (5) separating biodiesel (FAME) from glycerol by gravitational separation using a separating funnel; (6) purifying the biodiesel by washing with warm water to remove residual methanol and impurities and drying to remove excess moisture; (7) analyzing the biodiesel produced for compliance with fuel quality standards using techniques such as Fourier Transform Infrared (FTIR) spectroscopy and Gas Chromatography-Mass Spectrometry (GC-MS).
