182 million tons of refined oil and 9.412 million tons of ethylene were produced in 2006, increasing respectively by 4.5% and 22.2% on a year-on-year basis.
The results showed that the technological conditions of the most amount of (d)-Limonene were particle size 0.35mm, pressure 12MPa, temperature 36℃ and time 60 minutes, with 1.91% refined oil in separating container Ⅰ;
Linoleic acid was enriched by urea adduct method of the refined oil, resulting an increasing of linoleic acid methyl ester content from 78.39% of the crude oil to 93.75%.
α-linolenic acid was purified by urea inclusion treatment of the refined oil,resulting an increase of α-linolenic acid content from 57.05% of the crude oil to 84.24%.
The results showed that the optimum conditions of extraction technique with Supercritical CO_2 were at 30 MPa, 30 kg/h, 45 ℃, 180 min. Extraction rate can be up to 95.24%. The obtained oil is of pale yellow color and clear with right pure flavour, and the quality of product very similar to pure refined oil.
Two different techniques of extracting grape seeds were studied:the SCF-CO_2 extraction and solvent extraction. Physicochemical sanitation index,the fatty acids components,the content of trace minerals and the content of α-V_E of SCF-CO_2 extracted oil and the refined oil were examined and analyzed.
Application of membrane separation technique could improve the quality of refined oil and soybean protein isolate,prevent producing alkali washed wastewater,and high quality soybean lecithin,lysophosphatide and soybean oligosaccharide were obtained.
Under optimum operation conditions the acidity of refined oil was below 7.0 mgKOH/100mL, and the quality of recovered acid met the 65# petroleum acid standard (SH/T 0530-92).
Bromine number, sulfur content, nitrogen content and aromatic loss of the refined oil are less than 0.12 gBr/100g, 0.5 μg/g, 1 μg/g, and 1 percent point respectively. It is consistent with the Lab evaluation result.
Under an operating condition of 5. 0MPa, 270℃ a hydro-gen/oil volume ratio of 400:1 and a WHSV of 1.0h-1, the contents of sulfur and nitrogen and bromine index of the refined oil were less than 1μg/g, 1μg/g and 150mgBr/100g respectively, which met the hydrofining target of jet fuel.
The operation conditions of furfural refining are indicated: the mass ratio of solvent to oil is 1.93,extraction temperature is 95 ℃,under which the yield of refined oil is 85.3%.
When the feed was refined oil mixed with fly ash from a municipal waste incinerator, the carbon conversion and cold gas efficiency were 93% and 71.9%, respectively, with a slag conversion ratio of 0.93.
Oil of Spanish Bunch and Virginia Bunch genotypes is nutritionally better due to a higher concentration of linoleic acid and may be used as refined oil.
Litsea Cubeba is an aromatic plant widely covering the forestry areas of Sout. China. This article, based on observation and studying of Litsea Cubeba in the Jianyang County, Fujian province, clarified the form characteristics, plant climate period, fruit growth laws and the relation between the fruit drop rate and fruit density of the plant, and therefore, provided scientific information for its ground management, cultivation and refined oil production.
The stability of various rapeseed oils were determined in the laboratory,in order of the stability of this oils are:crude oil,degummed oil,refined oil,a part bleaching and deodorizing oil,the most bleaching and deodorizing oil.Compare the stability of degummed rapeseed oil to the refined rapeseed oil,then the degummed rape- seed oil is more stability than the refining oil.The results of various standard analysed explain that,the r...
In this paper,we show that:there are different effects on Acorus Cala- mus L refined oil rate according to different seasons,parts and refining metheds of Acorus Calamus L.So that,there are economial values when we plant Acorus Calamus L in our country sides
