A DIESEL PRODUCTION METHOD AND SYSTEM

摘要

A diesel production system (A) of the present invention comprises at least one furnace (F), at least one desulphurization reactor (4) and at least one modified dewax reactor (5) in which the catalyst therein is replaced with at least one hydrocracker catalyst (6). The diesel production method used in said system (A) comprises the following steps: pressurizing heavy hydrocarbon mixture (1) (101); heating the mixture (1) and hydrogen in said furnace (F) (102); receiving heated mixture (2) in the desulphurization reactor (4) (103); desulphurizing heated mixture (2) (104); and hydrocracking clean mixture (8) whose sulphur content is cleaned (105).
