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...

Activated clay minerals have been widely used in the edible oil refining industry for decolorization of crude oil by adsorption, and so far many methods have been used to improve their decolorization efficiency. Herein, we successfully prepared a series of carbon/attapulgite (C/APT) composite adsorbents by a one-step in-situ carbonization process with natural starch (St) as the carbon source. I...

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...

13 Oil wastes produced in large amounts in the processes of oil extraction, refining, and 14 transportation are of great environmental concern because of their mutagenicity, toxicity, high 15 fire hazardousness, and hydrophobicity. About 40% of these wastes contain radionuclides; 16 however, the effects of oil products and radionuclides on soil microorganisms are frequently 17 studied separatel...

Cedar wood oil is ranked the tenth essential oil in the world, it can be obtained from fir wood waste, and high added value Cedar series perfumes are obtained from Cedar wood oil by chemical processing. Their aroma is very unique and cannot be replaced. At present, the cedar wood resources are dwindling; a serious influence had taken place in the flavor and fragrance industry. Study found that ...

The production of fatty acid methyl esters (FAMEs) from waste activated bleaching earth (ABE) discarded by the crude oil refining industry using lipase from Candida cylindracea was investigated in a 50-L pilot plant. Diesel oil or kerosene was used as an organic solvent for the transesterification of triglycerides embedded in the waste ABE. When 1% (w/w) lipase was added to waste ABE, the FAME ...

Oil refining is an inevitable step in production of edible and industrial oil. Bleaching is the most important process among the refining processes. Bleaching adsorption is the most common method and clay is the most widely used adsorbent in this method. Disposal of bleaching clay, as a waste from re-refining plants, makes many environmental problems and economic losses. In the current study, t...

The article discusses the prospects for purification of industrial wastewater from phenols in oil refining, petrochemical and chemical industries with production waste. technological scheme treatment by modified carbonate sludge is given. In technologies, it proposed to use a large-tonnage energy waste - sludge. paper considers technology granulation, its characteristics are studied. To evaluat...

Rice bran oil is unique among edible oil due to its rich source of commercially and nutritionally important phytoceuticals such as, oryzanol, lecithin, tocopherols, and tocotrinols. However, most of these phytoceuticals are removed from the rice bran oil as waste byproducts during the refining process. γ-oryzanol is one of such component having the potential to be used in nutraceutical, pharmac...
