“…Although a large amount of KOH catalyst could accelerate the reaction rate, the FAME yield satisfied the criteria of the BDF standards (>96.5%) with KOH amount of 1.0 wt%. High‐quality BDFs were produced from Vernicia montana oil 39 and waste cooking oil 40 using acetone as a co‐solvent with 1.0 wt% KOH catalyst. These results were coincident with the present results.…”

Summary Previously, we have conducted the transesterification using isopropanol (IPA) as a co‐solvent for biodiesel fuel (BDF) production in the homogeneous condition (a single fatty acid methyl ester [FAME] phase). In this report, we investigated the transesterification kinetics by varying IPA amount and the optimum conditions for BDF production with 10 wt% IPA. In the IPA amount of 5 to 25 wt%, the transesterification proceeded in a heterogeneous condition (FAME and glycerol [GL] phases) as the GL phase was formed and separated from the FAME phase. The transesterification rate increased with the increase of IPA amount, and the correlation coefficient (r) between the rate constant and IPA amount was 0.97 (P < 0.05). The optimal conditions of transesterification for biodiesel production from canola oil with 10 wt% IPA were as follows: 1.0 wt% KOH, MeOH/oil molar ratio of 6:1, and a reaction temperature of 30°C. The quality of biodiesel satisfied the JIS K2390 and EN 14214 standards. Transesterification using 10 wt% IPA co‐solvent could facilitate the phase separation after the reaction, and the amount of waste was reduced. The recovery of IPA from FAME phase was >96%, hence IPA could be reused. These results indicated that IPA was a superior co‐solvent for the BDF production from plant oil feedstocks. Novelty statement Isopropanol as a co‐solvent for biodiesel production from canola oil was examined. Kinetic parameter of reaction rate was estimated. The transesterification proceeded rapidly with increase of isopropanol. The transesterification conditions were optimized for biodiesel production with 10 wt% of isopropanol.

Rubber seed oil (RSO) is a high‐potential feedstock for the production of biodiesel fuel (BDF) in Asia. Transesterification using fatty acid methyl esters (FAMEs) as co‐solvents was developed for BDF production from RSO with high content of free fatty acids (FFAs). The homogeneous system (FAMEs/triglyceride/methanol) was attained when the FAME content was more than 30 wt %. After esterification of RSO, the crude RSO obtained was transesterified with FAMEs as a co‐solvent. The quality of BDF with high FAME content satisfied the criteria of the EN 14214/JIS K2390 standards. These results suggest that FAMEs converted from FFAs can be applied as a co‐solvent and, thus, reused for BDF production.

“…Lao PDR has less developed plantation compared to other developing country like Thailand. Thus, Loa PDR Vernica Montana has seen as the most suitable raw material for biodiesel production in Laos since it can be cultivated under low-temperature/frosty conditions, non-edible, possess 40-60% oil in each seed and has low free fatty acid [272]. In addition to that, reforestation program enabled the plantation of Vernicia montana across Laos and Vietnam, which in turn to prevent land erosion and also to support the generation of oil for BDF production.…”

Biodiesel, comprising mono alkyl fatty acid esters or methyl ethyl esters, is an encouraging option to fossil fuels or diesel produced from petroleum; it has comparable characteristics and its use has the potential to diminish carbon dioxide production and greenhouse gas emissions. Manufactured from recyclable and sustainable feedstocks, e.g., oils originating from vegetation, biodiesel has biodegradable properties and has no toxic impact on ecosystems. The evolution of biodiesel has been precipitated by the continuing environmental damage created by the deployment of fossil fuels. Biodiesel is predominantly synthesised via transesterification and esterification procedures. These involve a number of key constituents, i.e., the feedstock and catalytic agent, the proportion of methanol to oil, the circumstances of the reaction and the product segregation and purification processes. Elements that influence the yield and standard of the obtained biodiesel encompass the form and quantity of the feedstock and reaction catalyst, the proportion of alcohol to feedstock, the temperature of the reaction, and its duration. Contemporary research has evaluated the output of biodiesel reactors in terms of energy production and timely biodiesel manufacture. In order to synthesise biodiesel for industrial use efficaciously, it is essential to acknowledge the technological advances that have significant potential in this sector. The current paper therefore offers a review of contemporary progress, feedstock categorisation, and catalytic agents for the manufacture of biodiesel and production reactors, together with modernised processing techniques. The production reactor, form of catalyst, methods of synthesis, and feedstock standards are additionally subjects of discourse so as to detail a comprehensive setting pertaining to the chemical process. Numerous studies are ongoing in order to develop increasingly efficacious techniques for biodiesel manufacture; these acknowledge the use of solid catalytic agents and non-catalytic supercritical events. This review appraises the contemporary situation with respect to biodiesel production in a range of contexts. The spectrum of techniques for the efficacious manufacture of biodiesel encompasses production catalysed by homogeneous or heterogeneous enzymes or promoted by microwave or ultrasonic technologies. A description of the difficulties to be surmounted going forward in the sector is presented.
