A review on biodiesel production using catalyzed transesterification
TL;DR: In this article, the main factors affecting the yield of biodiesel, i.e. alcohol quantity, reaction time, reaction temperature and catalyst concentration, are discussed, as well as new new processes for biodiesel production.
Journal ArticleDOI
Progress and recent trends in biodiesel fuels
TL;DR: The most important variables affecting methyl ester yield during the transesterification reaction are the molar ratio of alcohol to vegetable oil and the reaction temperature as discussed by the authors, which is the commonly used alcohol in this process, due to its low cost.
Journal ArticleDOI
The biorefinery concept: Using biomass instead of oil for producing energy and chemicals
TL;DR: In this article, the authors provide a description of the emerging biorefinery concept, in comparison with the current oil refinery, as well as discussion of the most important biomass feedstocks, conversion technologies and final products.
Journal ArticleDOI
Synthesis of Biodiesel via Acid Catalysis
TL;DR: A review of the research related to biodiesel can be found in this paper, where solid acid catalysts are used to replace liquid acids, reducing the corrosion and environmental problems associated with them.
Journal ArticleDOI
Review of biodiesel composition, properties, and specifications
TL;DR: In this paper, the fatty acid (FA) profiles of 12 common biodiesel feedstocks were summarized, and it was shown that several fuel properties, including viscosity, specific gravity, cetane number, iodine value, and low temperature performance metrics are highly correlated with the average unsaturation of the FA profiles.

Biodiesel fuel from rapeseed oil as prepared in supercritical methanol
Shiro Saka,Dadan Kusdiana +1 more
TL;DR: In this paper, the transesterification reaction of rapeseed oil in supercritical methanol was investigated without using any catalyst, and it was shown that in a preheating temperature of 350°C, 240 s of supercritical treatment of methenol was sufficient to convert the rapeseed oils to methyl esters.
