Biodiesel is generally made when fats and oils are chemically reacted with methanol, and a catalyst, typically sodium or potassium hydroxide (i.e., lye), to produce an ester, or biodiesel. Along with fuel ethanol, they qualify for use under the U.S. Renewable Fuel Standard (RFS) Program and may also qualify for use under state government fuel standards and programs. Biodiesel was successfully synthesized by silica-bound lipase in 96 h under shaking at 55C using 1 : 4 oil/methanol molar ratio. Biodiesel is a renewable fuel produced by the chemical reaction of methanol and vegetable oils or animal fats that is used a replacement or blender for diesel fuel. Long-chain alcohols such as 2-propanol and 1-butanol are also recommended for biodiesel production, especially when a high oil/alcohol (1:70) ratio is . . These properties have fulfilled the standard quality of biodiesel according to SNI-7182:2015. A preliminary investigation of the capabilities of the SBA-15, NH 2-Pr-SBA-15, and immobilized lipase at a preselected optimum loading ratio for biodiesel production has been performed under the following operating conditions:6 : 1 methanol:oil (M : O molar ratio), six wt.% nanobiocatalyst loading, 60 o C, three h, and 400 rpm.

So if the stoichiometric ratio of the oil you're using is 12.5%, that is 125 ml of methanol per litre of oil, the excess would range between 75 ml and 125 ml, for a total amount of methanol of 200-250 ml per litre of oil.

The lab-scale setup was designed and used for biodiesel prodn. Abstract. The methanol used in most biodiesel production processes is made using fossil fuel inputs. Biodiesel production using methanol as compared with ethanol is recommended because the ethanol purity is less than that of methanol. What does methanol have to do with biodiesel? Temperature has a significant positive effect on biodiesel purity and a significant negative influence on biodiesel yield. Springer Nature or its licensor (e.g. (2022)Cite this article.
