METHOD OF HYDROFINING LOW-TEMPERATURE FISCHER-TROPSCH DISTILLATE HAVING HIGH YIELD OF MIDDLE DISTILLATES

Title:

METHOD OF HYDROFINING LOW-TEMPERATURE FISCHER-TROPSCH DISTILLATE HAVING HIGH YIELD OF MIDDLE DISTILLATES

Document Type and Number:

WIPO Patent Application WO/2016/138832

Kind Code:

A1

Abstract:

A method of hydrofining a low-temperature Fischer-Tropsch distillate having a high-yield of middle distillates, the method comprising: dividing a low-temperature Fischer-Tropsch distillate having a high-yield of middle distillates into a light distillate, heavy distillate and middle distillate, and sequentially feeding the same into a first, second and third feed inlet of a hydrogenation reactor from an upper portion to a middle portion to perform a hydrofining process; respectively mixing a recycling hydrogen fed into a hydrogen inlet with three components in the hydrogenation reactor; and subsequently separating reaction products. The method maintains and controls a stable temperature of a refining reactor bed, reducing a feeding temperature of a heavy component, shortening a waiting time of a middle component, and reducing secondary cracking.
