Title:
COAL AND OIL HYBRID HYDROGENATION REFINING TECHNIQUE AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/124148
Kind Code:
A1
Abstract:
A coal and oil hybrid hydrogenation refining technique and device: preparing coal dust, residual oil, and recycled wax oil into a coal-oil slurry; mixing same with a catalyst, an additive, and hydrogen; implementing a thermal cracking and hydrogenation reaction in a slurry-bed reactor; placing all the products thereof into a thermal high-pressure separator; after separating the solids from the bottom and the gases from the top, implementing further hydrocracking or refining in a fixed-bed reactor; and placing the obtained distillate oil into a fractionation column, the wax oil at the bottom of the column being recycled wax oil. Re-using the produced wax oil as a coal-oil solvent oil reduces the viscosity of the coal-oil slurry, improves the fluidity of the coal-oil slurry, and increases the hydrogen production capacity of the liquid phase. The inside of the slurry-bed hydrogenation reactor is only provided with a medium distributor, and no bed layer support plate is arranged therein, reducing the medium pressure drop.
