“…Due to these advantages, biodiesel could be an appropriate substitute for conventional fuels. 3,4 This fuel is composed of fatty acid methyl esters (FAMEs) and could be effectively produced by either transesterification of triglycerides or esterification of free fatty acids (FFAs). 5 Biodiesel has a lot of advantages but also has some drawbacks that should be known such as bad compatibility with some materials (rubber) in some engines, and it is about one and a half times more expensive than petroleum diesel fuel.…”

Summary In this study, a strong acidic‐type cation exchange resin was used in the transesterification of corn oil to fatty acid methyl esters (FAME). The gel‐type cation exchange resin (Purolite‐PD206) was used in H+ and Na+ forms to utilize ion‐exchange resin as effective heterogeneous catalyst in the production of biodiesel. Effect of ionic forms of ion exchange resin on free fatty acid (FFA) conversion and composition was investigated by using different amounts of ion exchange resin (12, 16, and 20 wt%), various mole ratios of methanol to oil (1:6, 1:12, and 1:18 mol/mol), reaction temperatures (63, 65, and 67°C), and reaction time (24, 36, and 48 h) during transesterification reaction. The highest FFA conversions of 73.5% and 79.45% were obtained at conditions of 20 wt% of catalyst, 65°C of reaction temperature, 18:1 as methanol to oil ratio, and 48 h of reaction time for H+ and Na+ forms of ion exchange resin, respectively. These results were obtained from regression equations established by using analysis of variance (ANOVA) model according to the experimental results of selected parameters. Gas chromatography analysis revealed that FAME is mainly composed of C16:0 (palmitic), C18:1 (oleic), and C18:2 (linoleic) acids of methyl ester.

“…Compared to previous analysis (Table 1) minor differences in the elemental composition of the de-oiled PPW from Thailand used in this study and that from India or from seeds [15,26,27]. In general, the chemical composition of biomass shows a high variation due to many factors, such as cultivar, growth process, age, harvesting time and type of pesticide [28].…”

“…Generally, the reaction temperature decreases the viscosity of the reaction mixture and influences the collisions between substrates molecules. With temperature rises, the number of collisions between substrates molecules increases, resulting in an accelerated reaction rate . In addition, higher temperatures will lead to higher lipase deactivation .…”

BACKGROUND Enzymatic production of biodiesel is an alternative solution to circumvent the problems associated with chemical catalysis. However, the drawbacks, including lower stability and reusability of the lipase, often make this route unfeasible for industrial application. RESULTS A stable biocatalyst system was prepared by trapping an aqueous solution of Burkholderiacepacia lipase (BCL) in bead‐shaped silicone microspheres (named lipase‐based static emulsions). Compared with free BCL, lipase‐based static emulsions showed outstanding stability under vigorous shaking conditions and the thermal stability was improved. The lipase‐based static emulsions were employed to catalyze the transesterification of soybean oil with ethanol for biodiesel production. Under the optimum conditions, about 95.42% of FAEE yield was achieved in 30 h. In addition, the lipase‐based static emulsions presented good reusability, and the FAEE yield remained at more than 70.63% after 15 successive reaction cycles. The lipase‐based static emulsions were also used to catalyze the transesterification of jatropha oil and cottonseed oil with ethanol for biodiesel production, and the maximum FAEE yield was 96.10% and 90.39%, respectively. CONCLUSIONS Lipase‐based static emulsions were developed as robust biocatalysts by trapping an aqueous solution of lipase in silicone microspheres. The lipase‐based static emulsions catalyzed process may be a suitable technique for biodiesel production. © 2016 Society of Chemical Industry
