Optimization of Bleaching Process

Canola was developed from rapeseed using traditional plant-breeding techniques. Glucosinolate in rapeseed meal seed residue after oil extraction was detrimental to poultry, swine and ruminants. Hydrolysis of glucosinolates produced isothiocyanates and other sulphur-containing compounds, which interfere with iodine uptake by the thyroid gland, contribute to liver disease and reduce animal growth and weight gain. The economic viability of oilseed processing operations depends on the utilization of oilseed meal as animal feed. Erucic acid and glucosinolate content of the seeds had to be reduced for rapeseed meal to be used as animal feed. Brasicca species contain both spring and winter forms that are distinguished by vernalization exposure of plants or seeds to low temperatures to stimulate flowering or to enhance seed production requirement. Winter type B.

The invention relates to the field of oil product decolourization, in particular to a lubricating oil decolouring treatment method. The lubricating oil decolouring treatment method comprises the following steps of 1 providing a decolouring agent; providing lubricating oil which is not subjected to decolouring treatment; 2 performing impurity removal treatment on the lubricating oil which is not subjected to decolouring treatment; 3 adding the decolouring agent into the solution treated in the step 2 ; 4 separating the decolouring agent from the solution to obtain the decoloured lubricating oil. The lubricating oil decolouring treatment method provided by the invention has the advantages that convenience and high speed are realized; the requirements on the consumption of the decolouring agents, the decolouring treatment temperature, the decolouring treatment time and the stirring speed are not high; in addition, after the treatment by the lubricating oil decolouring treatment method provided by the invention, the decolouring rate of the lubricating oil is higher; in addition, the acid value cannot rise. Lubricating oil decoloration treatment method Technical field. The present invention relates to oil product decolouring field, and in particular to a kind of lubricating oil decoloration treatment method. As the lubricating oil consumption figure in the whole world increases, increasing waste lubricating oil is accordingly also caused to produce. Waste lubricating oil Landfill or burning, can be to ecological environment, while the healthy of the mankind can also be damaged indirectly.

This invention relates to an improved process for re-refining hydrocarbon oils. More specifically, this invention relates to a solvent refining process for reclaiming used lubricating oils. Still more specifically, this invention relates to a process for preparing quality lubricating oils from used waste lubricating and crankcase oils. Shortages of petroleum have renewed attention to developing methods for conserving dwindling world supplies of crude oil until science and technology can close the gap with stimulated production, alternative energy sources and more efficient energy utilization. One approach to this problem has been to encourage better utilization of present supplies, which includes an estimated 1 billion gallons of used lubricating oil that is drained, dumped or burned each year in this country. These oils have generally been used as engine crankcase lubricants, transmission and gear oils and the like.

Palm oil is an edible vegetable oil derived from the mesocarp reddish pulp of the fruit of the oil palms , primarily the African oil palm Elaeis guineensis , [1] and to a lesser extent from the American oil palm Elaeis oleifera and the maripa palm Attalea maripa. The use of palm oil in food and beauty products has attracted the concern of environmental groups; the high oil yield of the trees has encouraged wider cultivation, leading to the clearing of forests in parts of Indonesia and Malaysia to make space for oil-palm monoculture. One species in particular, the Sumatran orangutan , has been listed as critically endangered. Humans used oil palms as far back as 5, years. In the late s, archaeologists discovered a substance that they concluded was originally palm oil in a tomb at Abydos dating back to 3, BCE. Palm oil from E.

The bleaching of edible oils and fats is a part of the refining process of crude oils and fats, which removes contaminants that adversely impact the appearance and performance of these triglyceride triacylglycerol -based materials. Typically, edible oils and fats, ranging from soybean and palm oils to edible lard and beef tallow, are extracted together with impurities in various quantities. Many of these impurities have to be removed from the oil to achieve the high quality oil standards necessary for edible applications.

Третий узел был пуст, свет шел от работающих мониторов. Их синеватое свечение придавало находящимся предметам какую-то призрачную расплывчатость. Она повернулась к Стратмору, оставшемуся за дверью. В этом освещении его лицо казалось мертвенно-бледным, безжизненным. - Сьюзан, - сказал .

Шум и мелькающие огни в шифровалке делали ее похожей на стартовую площадку ракеты. Хейл зашевелился и в ответ на каждое завывание сирены начал моргать. Неожиданно для самой себя Сьюзан схватила беретту, и Хейл, открыв глаза, увидел ее, стоящую с револьвером в руке, нацеленным ему в низ живота. - Где ключ? - потребовала .
