1.The results showed that HVI lube base oils with good oxidization stability could be prepared by high pressure hydrotreating or solvent refining medium pressure hydrotreating along with solvent dewaxing.
中型试验结果表明 ,采用高压加氢处理、溶剂精制 -中压加氢处理技术 ,配以溶剂脱蜡可以制取氧化安定性好的 HVI润滑油基础油 ;收藏指正
2.Using the hydrotreated lube base oils of 125N, 200N, 400N and 120BS from Lanzhou Petroleum Refining and Petrochemical Company as feedstocks, the filtration effects of polyolefin/polypropylene-acid-ester dewaxing aids having different relative molecular masses with designations of DEW-6, DEW-7 and DEWo8 were evaluated in the laboratory.
以兰炼加氢处理的125N、200N、400N及120BS润滑油基础油为原料,对不同相对分子质量的聚烯烃/聚丙烯酸脂脱蜡助剂DEW-6、DEW-7、DEW-8的脱蜡助滤效果在实验室进行了评价。 评选工艺采用关键单元的间歇式过程。收藏指正
3.Lube oil distillates,which were from the mixture of Daqing crude oil and Russian crude oil in the different proportion at 350～400℃,400～450℃ and 450～500℃,were treated by acetone-benzol dewaxing,furfural refining and clay refining. The typical base oils were obtained and evaluated.
大庆原油与俄罗斯原油按不同比例混合的350~400℃、400~450℃和450~500℃润滑油馏分油经过酮苯脱蜡、糠醛精制和白土精制后,得到基础油典型馏分油,进行润滑油基础油性质评价;收藏指正
4.The solvent refining,hydrotreating and catalytic dewaxing of processing lube oil by the crude oil from Iran and Saudi Arabia were described. Their Technical-economic status was also compared
对伊朗和沙特阿拉伯原油生产润滑油，从溶剂精制、加氢处理、催化脱蜡进行了阐述，并对两种原油生产润滑油技术经济进行了比较。收藏指正
5.The test result shows that the furfural refining lube oil from Liaohe low-freezing crude oil has low wax content and can be processed into qualified LVI base oils after removing a little naphthenic wax. The optimum oil-solvent ratios are obtained in the lube oil solvent dewaxing process, in which,the dewaxing capacity increases and the freezing point of the dewaxed oil decreases apparently as the dewaxing temperature decreases.
试验结果表明:辽河低凝原油润滑油糠醛精制油蜡含量很低,脱除少许环烷蜡即可生产出合格的LVI基础油,润滑油溶剂脱蜡有一最佳油剂比,随着脱蜡温度的下降,润滑油脱蜡量增加,脱蜡油凝点明显降低。收藏指正
