    • A process for manufacturing a lubricating base oil, comprising dewaxing a substantially paraffinic wax feed by hydroisomerization dewaxing using a shape selective intermediate pore size molecular sieve under hydroisomerization conditions including a hydrogen to feed ratio from about 712.4 to about 3562 liter H2/liter oil, whereby a lubricating base oil is produced having a)a total weight percent of molecules with cycloparaffinic functionality greater than 10, and b) a ratio of weight percent molecules with monocycloparaffinic functionality to weight percent molecules with multicycloparaffinic functionality greater than 30. Also a method for producing a base oil having a high ratio of weight percent molecules with monocycloparaffinic functionality to weight percent molecules with multicycloparaffinic functionality by hydroisomerization dewaxing a selected Fischer-Tropsch wax under hydroisomerization conditions including a hydrogen to feed ratio from about 712.4 to about 3562 liter H2/liter oil. Also a lubricating base oil manufacturing plant.
    • 一种润滑油基础油的制造方法,其特征在于,在加氢异构化条件下,通过使用形状选择性中等孔径分子筛,通过加氢异构化脱蜡将大体上链烷烃化的蜡进料脱蜡,所述加氢异构化条件包括氢与进料比约为712.4〜3562升H 2, / l油,由此产生润滑基础油,其具有a)具有大于10的环烷烃官能团的分子的总重量百分比,以及b)分子与单环烷烃官能团的重量百分比与重均分子百分比的多环烷烃官能团的比例更大 30.另外,通过在加氢异构化条件下加氢异构化脱蜡选择的费 - 托蜡来生产具有高单体重量百分比的分子与单环烷属官能度的重量百分比的基础油的方法,其中多烷基官能度分子的重量百分比为约712.4 至约3562 升H 2 /升/升油。 也是润滑油基础油生产厂。
