Reactors for biodiesel production occurs during the supercritical state of methanol (typically 300°c and 40 mpa/5800 psi or higher), the vegetable oil or animal . Biodiesel production from rapeseed oil using supercritical methanol produced 95% methyl ester within 4 min (rapid reaction) with no side reactions or unwanted products, despite the presence of high free fatty acid (high acid value) and water. Synthesis of linseed oil biodiesel using a non-catalytic supercritical the process biodiesel production is in itself time refined lard in supercritical methanol was performed to. Biodiesel production continues to grow around the globe, with everything from large-scale commercial operations to smaller, backyard blenders mixing this environmentally-friendly fuel for everyday use in diesel engines.
Supercritical methanol (scme), the critical parameters of which are critical temperature (t c)=2394°c, critical pressure (p c)=81 mpa, and ρ c =0276 gcm-3, was one of the first scfs evaluated for the production of biodiesel the promising results obtained with supercritical alcohols, have led to many studies on the effects of various . Enzymatic production of biodiesel from waste animal fat using immobilized reactant concentration due to the enzyme inhibition of methanol supercritical co. Biodiesel production using supercritical methanol with carbon dioxide and acetic acid chao-yiwei,tzou-chihuang,andho-hsienchen biodiesel production l factors.

Deshpande, shriyash rajendra, production of biodiesel from soybean oil using supercritical methanol (2016) chapter 3: biodiesel production using supercritical .
Abstract: the continuous production of biodiesel (fatty acid methyl esters) by the transesterification reaction of coconut oil and palm kernel oil was studied in supercritical methanol without using any catalyst experiments were carried out in a tubular flow . Recent years have seen great efforts made to optimise the production of biodiesel as an alternative to fossil fuel this study looks at the optimal conditions for producing second generation biodiesel in supercritical methanol from jatropha oil. The production of biodiesel by different supercritical tech- nologies using as reactants methanol in single-step and two-step processes: methyl acetate and acetic acid. The continuous production of biodiesel (fatty acid methyl esters) by the transesterification reaction of coconut oil and palm kernel oil was studied in supercritical methanol without using any catalyst.
Continuous production of biodiesel from vegetable oil using supercritical ethanol/carbon dioxide mixtures asantana , j maçaira, f recasens, m a larrayoz. Advanced engineering research: biodiesel production from crude rubber seed oil using supercritical methanol transesterification. In order to prevent the production of glycerol as a by-product, methyl acetate instead of methanol is used under supercritical conditions the supercritical methyl acetate method converts triglycerides into fatty acid methyl esters (fames) and triacetin, instead of glycerol without catalyst.
