One of the keys to making biodiesel a viable and profitable energy source is the use of a continuous flow transesterification process to reduce time and cost, thereby increasing production and profit. Sodium hydroxide and methanol were used as catalyst and solvent respectively while n-hexane was added as a co-solvent. In order to facilitate the search for potentially useful species/strains, in this work, a bioprospecting tool based on biomass and oil production process requirements, triacylglyceride content, and biodiesel properties has been developed.

Biodiesel is usually produced from food-grade vegetable oils using transesterification process. The book focuses towards the strategies to ensure the availability of algal biomass, effective cultivation and harvesting techniques. Initial process development was performed with synthetic mixtures containing 20% and 40% free fatty acids, prepared using palmitic acid. The induction periods for the methyl and ethyl esters from the high-oleic feedstock were 14 and 26 h, respectively, according to the Rancimat method. Microalgae are a promising alternative source of lipid for biodiesel production. Monyem, A.; Canakci, M.; Van Gerpen, J. H. 2000.

A continuous flow esterification process for producing biodiesel from rapeseed oil and ethanol was investigated. ARTICLE INFO. Insect fat has also been proposed as a promising resource for biodiesel production. Although the production of biodiesel involves a relatively simple chemical process, there is potential for various contaminants to be present in the fuel. Typically, to a mixture of olive oil (7.9 mL) and methanol (1.0 mL) in screw-capped glass tubes, 2.6 mL of purified lipase was added and incubated for 16 h at 40 °C with stirring at 200 rpm. A comprehensive study of biodiesel preparation from canola oil was performed on a continuous-flow reactive distillation (RD) reactor system. A complete set of fuel properties and a comparison of each fuel in engine performance tests are reported. Much of the process complexity originates from contaminants in the feedstock, such as water and free fatty acids, or impurities in the final product, such as methanol, free glycerol, and soap.

Specifically, biochar derived from the pyrolysis of PW was used as a catalytic and porous medium for biodiesel production to enhance reaction kinetics and lower reaction temperature, compared to conventional methods. The acid catalyst also requires the concentration of water to be less than 0.5%, which is about the same as is required for alkaline catalysts. ASTM standard methods were implemented to examine the microalgae properties, including proximate and ultimate analyses.
