Abstract: A process for obtaining improved hydrocarbon oil products by treating by-product heavy fractions, formed in the production of olefins and having initial boiling point of above 160*C and a 75 percent distill-off point of below 450*C, with hydrogen at a temperature of from 40* to 200*C and a pressure of from 5 to 300 kg/cm2 G using a nickel-containing catalyst which has been pretreated with organic sulfur compounds, to thereby impart thermal stability to the oil, then subjecting the resulting oil to a hydrorefining followed by hydrogenation is disclosed.
