A single-step batch transestenfication process that uses sodium hydroxide catalyst has been developed for the conversion of refined vegetable oils to biodiesel methyl esters that meet biodiesel standards particularly with regard to glyceride content and acid number. Tetrahydrofuran is used as a cosolvent to form a single phase for the initial homogeneous reaction. The optimal methanol to oil molar ratio is 12:1 and the optimal sodium hydroxide catalyst concentration is 0.74 wt% based on the oil. A glycerol-rich phase separates during the reaction and mixing is required to remove hydroxide ion to this phase and provide methoxide ion to the methyl ester-rich phase. Biodiesel standard product is formed in 15 minutes in a continuously mixed batch reactor at 23ʻC. Two proposed isolation and purification treatments have been tested successfully to remove the solvents, mineral acid, salt of mineral acid, glycerol, and glycerides to refine the crude methyl ester products.

Transesterification is one of the methods for biodiesel production in which oil or fat is reacted with alcohol, such as methanol or ethanol, in the presence of a catalyst to form alkyl ester and Author: Sarina Sulaiman.
The biodiesel yield could be improved by introducing excess amounts of methanol to shift the equilibrium to the right-hand side. The experimental results, illustrated in Fig. 3, indicate the molar ratio of methanol to oil has a significant impact on the biodiesel biodiesel yields grew as the molar ratio increased, and the yield was 75% at a molar ratio of methanol to oil when Cited by: Biodiesel Education Program at the University of Idaho.

Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and involves vegetable or animal fats and oils being reacted with short-chain alcohols (typically methanol or ethanol).The alcohols used should be of low molecular weight.
Ethanol is the most used because of its low cost, however, greater.

Currently, biodiesel is produced in a batch process. This study considers using a new microreactor based reaction process for transesterification of soybean oil to biodiesel (methyl esters).Cited by: between batch and continuous process for the production of biodiesel (especially from soybean oil) is limited.
On the other hand, previous literature, related to batch and continu-ous production, agreed that raw material is the largest con-tributor to the production cost; for instance, Haas, M. J., et. requires careful removal of catalyst from the bio-diesel fuel since acid catalyst residues can damage engine parts (Zhang et al., ; Vyas et al., ; Abbaszaadeh et al., ).
This is one of the main reasons why most biodiesel standard specifications place a. A pilot-scale batch reactor with a biodiesel production capacity of 20 gallons per batch was set up and used for the catalyst testing and biodiesel production.

The supercritical processing of fats and oils for biodiesel production takes advantage of the enhanced miscibility of alcohol and triglycerides at these conditions to conduct the transesterification reaction in a homogeneous phase without using a catalyst (Sawangkeaw, Bunyakiat & Ngamprasertsith, ).Author: Paola-Andrea Marulanda-Buitrago, Víctor-Fernando Marulanda-Cardona.
In this paper, we evaluate batch and continuous processing options for biodiesel production from the economical point of view. The economic feasibility of biodiesel as well the plants configuration not only depends on technical design aspects but also on other important factors such as seasonal variation of feedstock, transportation costs, and.

Within the United States it is commonly produced from soybean oil. In conventional production of biodiesel, the transesterfication reaction is typically catalyzed in batch reactors with reaction times greater than 1 hour.
They analyzed emissions according to the feedstock used for biodiesel production—soybean oil, palm oil, waste frying oil—through the methyl and ethyl routes. Besides that, the Tukey test was used, showing that, in general, higher engine loads led to a decrease in CO 2 emissions in comparison with the standard B4 (4% biodiesel) blend Cited by: 1.
The reaction of vegetable oil/fat for the production of biodiesel usually takes place in an enclosed device known as a “reactor”.

Response surface methodology (RSM) and Box-Behnken design were employed to evaluate the effects of reaction temperature, flow rate, and substrate molar ratio on the molar conversion of by: To us, the path ahead was clear: The biodiesel industry needed a fully continuous, fully integrated production refinery for biodiesel—one that could receive a variety of feedstocks and process them continuously to biodiesel and glycerin.
The fixed-bed reactor design and our new catalyst were at the heart of this approach. In the present study, we synthesized biodiesel from soybean oil through a transesterification reaction catalyzed by lithium carbonate.

Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid is typically made by chemically reacting lipids such as animal fat (), soybean oil, or some other vegetable oil with an alcohol, producing a methyl, ethyl or propyl ester.
Unlike the vegetable and waste oils used to fuel converted diesel engines, biodiesel is a drop-in biofuel.Soybean oil remained the largest biodiesel feedstock during February with million pounds consumed.
