Abstract:

Objective Solve the single raw material problem of rubber filling oil production. Methods All-hydrogen hydrogenation tests were carried out on the mixed oil of intermediate base and naphthyl using hydrogenation catalysts A and B, heterogeneous dewaxing catalyst C and supplementary refining catalyst D. Results Under the conditions of temperature of 382 ℃, 315 ℃, 240 ℃, space velocity of 0.4 h-1, 1.0 h-1, 0.6 h-1, hydrogen to oil ratio of 1 000∶1,800∶1,800∶1, the viscosity of 380-400 ℃ fraction at 100 ℃ was 6.208 mm²/s, CA value was 0, CN value was 56.1%, which met the standard of rubber oil N4006 in HG/T 5085-2016 Rubber plasticizer-naphthene base mineral oil. The viscosity of 400-440 ℃ fraction at 100 ℃ was 9.565 mm²/s, CA value was 0, CN value was 54.7%, which met the standard of rubber oil N4010 in HG/T 5085-2016. The viscosity of the fraction above 440 ℃ at 100 ℃ was 15.94 mm²/s, the CA value was 0, and the CN value was 51.5%, which met the standard of rubber oil N4016 in HG/T 5085-2016. Conclusion Above results verified the feasibility of intermediate base oil blended with naphthenic oil to produce rubber filling oil.
