Abstract

Abstract:

In response to the characteristics of slurry-bed diesel distillate—high nitrogen content, high aromatic content, and low cetane number—highly active denitrogenation hydrotreating catalyst RNS-100 and highly selective ring-opening hydro-upgrading catalyst RUS-100 were developed. Pilot-scale tests showed that using slurry-bed diesel as feedstock and applying hydro-upgrading technology under a hydrogen partial pressure of 12.0 MPa can produce heavy naphtha with aromatic potential above 58.1%, diesel with sulfur content below 10 μg/g and cetane number above 51.8, and jet fuel meeting No. 3 jet fuel specifications. Industrial unit calibration results confirmed that using slurry-bed naphtha and diesel fractions as feedstocks can produce heavy naphtha with 51% aromatic potential, jet fuel with a smoke point of 24.0 mm, and China-VI clean diesel with a cetane number of 65.0.

摘要：

针对浆态床柴油馏分氮含量高、芳烃含量较高和十六烷值较低的性质特点，开发了高脱氮活性的加氢精制RNS-100催化剂、高开环选择性的加氢改质RUS-100催化剂。中型试验结果表明，以浆态床柴油为原料，采用加氢改质技术，在氢分压12.0 MPa条件下，可以生产芳烃潜含量大于58.1%的重石脑油，柴油产品硫质量分数小于10 μg/g、十六烷值大于51.8，喷气燃料产品满足3号喷气燃料指标要求。工业装置标定结果表明，以浆态床石脑油和柴油馏分为原料，可以生产芳烃潜含量为51%的重石脑油、烟点为24.0 mm的喷气燃料和十六烷值为65.0的国Ⅵ清洁柴油。
