摘要
对不同性质的柴油,可采用不同的加氢脱硫脱芳烃工艺技术生产清洁柴油。直馏柴油和焦化柴油采用单段加氢工艺技术,在适宜的工艺条件下,可以生产硫质量分数低于300μg/g、芳烃质量分数低于25％、十六烷值大于53的清洁柴油;劣质催化裂化柴油采用单段加氢工艺及催化剂匹配装填技术,在适宜的工艺条件下,可以生产密度0.8576g/cm^3、硫质量分数5.0μg/g、芳烃质量分数29.6％、十六烷值39.8的清洁柴油组分;劣质催化裂化柴油采用两段加氢工艺技术,可以生产密度0.850 6 g/cm^3、硫质量分数1.2 μg/g、芳烃质量分数16.5％的清洁柴油组分。
Different hydrogenation processes have been adopted to process diesels with different features and produce clean diesel fuel. Clean diesel fuel with sulfur content lower than 300 ug/g, aromatics content lower than 25% and the cetane number over 53 has been produced from straight run diesel and coker diesel under the proper operation conditions with the single-stage hydrogenation process. As for inferior FCC diesel, using single-stage hydrogenation process combined with catalysts, clean diesel fractions with density 0.857 6 g/cm , sulfur content 5.0 ug/g, aromatics content 29.6% , cetane number 39.8 have been produced. When inferior FCC diesel is processed with two-stage hydrogenation process, clean diesel fractions with density 0.850 6 g/cm , sulfur content 1.2 ug/g and aromatics content 29.6 % can be produced.
