Its manufacture process includes the deasphalting of the vacuum-pressure residual oil, solvent refining, solvent-dewax, refining, shaping and packing.
Using solvent refining technique to produce rubber oil from furfural extract oil and catalytic cracking cycle stock was studied.
Saturated hydrocarbons content of CGO been increased by about 10 percent points and the nitrogen content decreased significantly after solvent refining.
