Abstract: The experiment on hydrodewaxing process using the Bohai bay naphthenic crude oil third vacuum side distillate oil to product rubber filling oil was studied. The result show that using high-pressure hydrodewaxing process, under the conditions of LHSV 0.18 h-1, H2/oil (volume ratio) 800∶1, reaction pressure 15 MPa, reaction temperature about 320~380 ℃. The freezing point of fractions above 320 ℃ declined to -26 ℃, the contents of sulfur and nitrogen decreased to 12 μg/g and 8 μg/g respectively, and aromatic content went down from 36.8% to 4.3%. The properties of fraction above 320 ℃ were similar to the import extender oils of SBS.
