石蜡馏分

with the hydroisomerization dewaxing process of shell company, apiⅱgroup and apiⅲgroup lube base oils were produced by taking vgo no.4 and dao from xinjiang karamay paraffin crude oil as raw materials after a series of lab tests and commercial trial production. the developed oils can meet the quality requirements of hviwh300 and vhvih90bs respectively. but all the haze points of the two products are about 16 ℃, and the floccus will appear in these oils with the time going by. the problem of haze point in high viscosity lube oil will still need to study continually.

采用壳牌公司以异构脱蜡催化剂为核心的全加氢工艺，对新疆克拉玛依石蜡基原油减四馏分油、轻脱油进行了实验室工艺研究，并经工业试生产，可以生产出apiⅱ、ⅲ类润滑油基础油，其主要产品性质可以分别满足中国石油hviwh300、vhvih90bs的质量要求，但这两种大粘度产品浊点达到16 ℃左右，室温下长期存储会出现絮状物，需要进一步研究解决。

Make incomplete heavy oil or olefin base crude oil comes to those who raise light oil close through deepness treatment method rate, finished product can serve as after classics of the benzine of generation, derv is purificatory, shan of the cent that weigh heat up in a steamer can serve as catalytic cracking or thermal cracking raw material, coke can serve as the raw material of production electrode, have ask rest method and continuous method etc.

使残重油或石蜡基原油通过深度加工方法来提高轻油的收率，产生的汽油、柴油经精制后可作为成品，重馏分汕可作为催化裂化或热裂化原料，焦炭可作为制造电极的原料，有问歇方法和连续方法等。
