This technology has incorporated the technical advantages of both hydrofining and hydro-upgrading and introduced the separated feed to different zones in order to increase the selectivity of reaction process, reduce the equipment investment cost and operating cost, and achieve obvious economic benefits, which can provide a technical guarantee for the supply of clean diesel fuel meeting the national Ⅴ quality standard.展开更多
