3、Considering the high contents of olefins and nitrogen, the whole fraction of delayed coker distillates (including light and heavy naphtha, gas oil) must be hydrotreated.
2、A hydrocracking catalyst named 3825 was developed to produce heavy naphtha for reforming feedstock from vacuum gas oil. This catalyst also has the flexibility to produce naphtha with jet fuels.
4、The heavy naphtha produced from hydrocracking plant of SINOPEC Tianjin Company was disqualified due to the high total sulfur content and related investigation was carried out to solve the problem.
1、Other feed stocks can include ethane, propane, butane, and light and heavy naphtha but are not commonly used.
