摘要： The invention discloses a rubber process oil and a process for manufacturing rubber process oils which are non-carcinogenic in nature. The process comprises of selectively producing Hildebrand solubility components enriched vacuum residue by selective distillation of reduced crude oil (RCO) to obtain minimum of 10 vol % boiling components in the range 490° C. to 50° C., which leads to higher solubility of rubber process oil with an aniline point of less than 70° C. and with extremely low concentration of selective polycyclic aromatics which makes the 15 product non-carcinogenic. The process comprises of selectively enriching higher Hildebrand solubility components in vacuum residue by vacuum distillation of reduced crude oil (RCO), then subjecting the enriched vacuum residue to solvent deasphalting process and subjecting the deasphalted oil to aromatic extraction process and then blending the enriched aromatic extract with Heavy Alkyl 20 Benzene (HAB) or Solvent processed base oil or hydroprocessed base oil or mixture thereof. The rubber process oils manufactured by the invented process have a polycyclic aromatics (PCA) content of less than 10 ppm, specifically benzo(a)pyrene content of less than 1 ppm. They have aniline point less than 70° C. but have high kinematic viscosity of 25 to 75 cSt at 100° C., pour point of 27° C. or less and a flash point minimum of 250° C. or more.

摘要翻译：本发明公开了一种橡胶加工油及其制造方法，该方法在本质上是非致癌的。该方法包括通过选择性蒸馏还原原油（RCO）选择性地生产富含真空残渣的希尔德布兰德溶解度成分，以获得在490℃至50℃范围内的最低10vol％沸点组分，这导致更高的溶解度橡胶加工油，苯胺点小于70℃，极低浓度的选择性多环芳烃使15种产品不致癌。该方法包括通过减压原油（RCO）的真空蒸馏选择性地富集真空残渣中较高的希尔德布兰德溶解度成分，然后将富集的真空残渣进行溶剂脱沥青处理，并对脱沥青油进行芳族萃取过程，然后将富集的芳香提取物与重烷基20苯（HAB）或溶剂处理的基础油或加氢基础油或其混合物。通过本发明方法制造的橡胶加工油具有小于10ppm的多环芳烃（PCA）含量，特别是苯并（a）芘含量小于1ppm。它们的苯胺点小于70℃，但在100℃下具有25至75cSt的高运动粘度，倾点为27℃或更低，闪点最低值为250℃或更高。
