An alternative route to produce biodiesel is based on esterification of free fatty acids present in byproducts obtained from vegetable oil refining, such as palm oil fatty acid distillate (PFAD). PFAD is a byproduct of the production of edible palm oil, which contains 96 wt.% of free fatty acids. The purpose of this work was to study biodiesel synthesis via esterification of PFAD with methanol ...

Converting waste cooking oil into biofuel represents a three-win solution, dealing simultaneously with food security, pollution, and energy security. In this paper, we encode the policy documents of waste cooking oil refining biofuel in China based on content analysis, and explore the related policies from the two dimensions as basic policy tools and enterprises supply chain. Research indicates...

Erythromycin production is clearly enhanced by the addition of vegetable oils. However,whether this positive effect is brought about by the triglyceride or non-triglyceride fraction, isnot clear. The non-triglyceride portions of the oils accumulate in the waste during the refiningprocess leaving mainly triglycerides in the refined oil. In this research, sub-fractions of soybeanoil, including le...

3-monochoropropane-1, 2-diol (3-MCPD) and 2-monochloropropane-1,3-diol (2-MCPD) and glycidol esters (GE) have been known as food contaminants. These compounds are formed during high-temperature process of different food products such as coffee, edible oils, infant formula, potato based products, bakery products, malt, cooked meats, soy sauces and pickles. In vegetable oils, these compounds are ...

Crude oil blending is an important unit operation in petroleum refining industry. There are two difficulties for commercial crude oil optimizing controllers: (1) the optimization is stable only in some special conditions, the simplex-base algorithm is not robust; (2) the optimal control should be realized on-line and it cannot be analyzed off-line based on the history data. In this paper, we pr...
