PROCESS OF PRODUCING MIDDLE DISTILLATES VIA HYDROISOMERIZATION AND HYDROCRACKING OF TWO FRACTIONS OF PRODUCTS OBTAINED IN FISCHER-TROPSCH PROCESS AND APPARATUS FOR IMPLEMENTATION OF THE PROCESS Russian patent published in 2006 - IPC C10G65/12

Abstract RU 2283858 C2

FIELD: petroleum processing and petrochemical industry.

SUBSTANCE: paraffin feedstock is fractioned to produce intermediate fraction having starting boiling point from 120 to 200^°C and dry point from 300 to 410^°C. light fraction boiling below intermediate fraction and heavy fraction boiling higher than intermediate fraction. At least part of intermediate fraction is subjected to hydrofining and then passed through hydrocracking/hydroisomerization catalyst, wherein conversion of hydrocarbons boiling at or higher than 370^°C into products boiling below 370^°C exceeds 80 wt %. At least part of hydrocracked/hydroisomerized fraction is then distilled.

EFFECT: improved quality and yield of desired products.

13 cl, 1 dwg, 12 tbl
