Abstract
A combined hydrogenation process method for producing high-quality fuel by medium-low-temperature coal tar, wherein a medium-low-temperature coal tar is fractionated to obtain a final product through a thermal hydrocracking unit, a first atmospheric fractionation unit, a hydro-refining, unit, a vacuum fractionation unit, a diesel and wax oil hydro-upgrading unit, a wax oil hydro-cracking unit, a gasoline and diesel precious metal hydrogenation unit and a fourth atmospheric fractionation unit. The present invention can effectively improve the quality of naphtha, aviation kerosene and diesel products, and produce high-end products with high yield and high value, and thus it has a great prospect of promotion and application.
