以“蓝”之名清洁柴油技术

现在的柴油技术已经可以做到“环保”和“高效”兼得了，所以我们把它应有的蓝色还给它。

延安炼油厂汽柴油加氢工艺路线的选择

延安炼油厂原油一次加工能力800万吨／年，二次360万吨／年，其中直馏柴油268万吨／年，硫含量在450ppm左右；催化汽油180万吨／年，硫含量在120ppm左右。为了能满足国Ⅳ质量标准，延安炼油厂根据原油性质和生产工艺，通过对目前国内外汽柴油清洁技术对比分析，汽油拟采用S-Zorb技术吸附，柴油采用FHI柴油加氢改质异构降凝技术，将柴油硫含量降到67ppm以下，催化汽油降到75ppm以下。

Medium-Pressure Hydro-upgrading (MHUG) Technology for Producing Clean Diesel Fuel

Abstract： This article introduces the development and application of the medium-pressure hydro-upgrading （MHUG） tech- nology developed by the Research Institute of Petroleum Processing （RIPP）. The MHUG technology based on the chemistry of diesel hydro-upgrading reactions has the advantages of flexible product slate and excellent product quality that can in- crease the cetane rating of diesel fuel up to more than 15 units. The hydrotreating and hydro-upgrading catalysts associated with the MHUG technology have outstanding performance to meet the demand of MHUG technology for hydro-saturation and selective ring-opening of aromatic rings. New MHUG process flow scheme can further increase the yield and selectivity of target products. Commercial application of multiple MHUG units has revealed that the MHUG technology designated for clean diesel production features good feedstock adaptability and operating stability.
