The blending of straight-run diesel oil in catalytic cracking unit was analyzed.In the process of reducing the ratio of diesel to gasoline,a petrochemical company blended 10% of the straight-run heavy diesel oil into two sets of catalytic cracking unit to make the gasoline yield increased by 0.3% ～1% ,liquefied gas yield increased by 0.3% ～1% ,diesel yield decreased by 0.5% ～2.5% under the condition of quality comformance and without big operating parameters change.It had significantly reduced the ratio of diesel to gasoline,accumulated some operating experience for the subsequent unit of straight-run diesel mixing and accumulated data for the whole plant to reduce the ratio of diesel to gasoline.
