A process and system for separating a light fraction, a bio-distillate fraction, and a heavy fraction from a bio-oil, and for producing a renewable distillate including at least in part the bio-distillate fraction and a stabilizing additive, is provided. The process comprises separating bio-oil into light, bio-distillate, and heavy fractions based on their boiling points. At least a portion of the bio-distillate fraction and a stabilizing additive are blended with a petroleum-derived-diesel-range stream, without any prior hydrotreatment, to thereby provide a renewable distillate composition.
