The co processing provides control of the hydroconversion reactions of the triglycerides and fatty acids of biomass oil diluted in a refinery stream of petroleum hydrocarbons and minimizes the generation of gaseous products that are undesirable to the process, while maintaining the levels of unsaturated hydrocarbons hydrogenation and of {HEAD ~ heteroatomic contaminants removal} from {TAIL ~ the refinery stream} of petroleum hydrocarbons
