Supercritical transesterification: Impact of different types of alcohol on biodiesel yield and LCA results

Improvement of oxidation stability of fatty acid methyl esters derived from soybean oil via partial hydrogenation using dielectric barrier discharge plasma

“…Biodiesel is a clean, locally available, sustainable, and renewable fuel, which has received increasing attention for the current and future utilizations on transportation, power generation, heating system, and so on. Biodiesel can be synthesized via transesterification by a reaction between vegetable oils, or animal fats, and alcohol (methanol or ethanol) with a suitable catalyst in mild conditions, or without a catalyst in supercritical conditions 1‐3 . In the case of using methanol as alcohol, biodiesel is called fatty acid methyl esters (FAME).…”

“…Biodiesel can be synthesized via transesterification by a reaction between vegetable oils, or animal fats, and alcohol (methanol or ethanol) with a suitable catalyst in mild conditions, or without a catalyst in supercritical conditions. [1][2][3] In the case of using methanol as alcohol, biodiesel is called fatty acid methyl esters (FAME). Biodiesel offers considerable advantages over petroleum-based diesel, such as higher cetane number, safer due to high flash point, less emission, higher lubricity, and better in combustion.…”

Life cycle assessment as a tool for evaluating chemical processes at industrial scale: a review

“…Most of the studies (55%) were performed in European countries. 14–17,20,22,23,26,28,30,32,35,39,40,47–57 This is an expected result given that LCA is an official and standardized tool for assessing the environmental impacts in the EU, mostly since its Communication on Integrated Product Policy (COM (2003)302). About the rest of the papers, 24% of the studies were performed in Asia, 19,21,27,33,34,37,41–44,58–60 11% in Central or South America, 18,29,38,43,45,46,61 8% in North America, 31,36,43,59,60 and 2% in Africa and Oceania.…”

Synthesis of mesoporous calcium titanate catalyst for transesterification of used cooking oil: A review of the synthesized potential

“…In contrast, the application of UCO as a biodiesel feedstock may solve the problem of waste oil disposal as most of UCO is thrown as waste, that are then discharged to surface waters, leading to water pollution (Math et al, 2010;Tsoutsos et al, 2016). Table 3 shows the general chemical and physical properties of a UCO sample collected by various researchers (Kiss et al, 2014;Pukale et al, 2015;Yaakob et al, 2013).…”
