Title:
METHOD AND EQUIPMENT FOR SLURRY BED HYDROGENATION MIXED REFINEMENT OF OIL AND COAL
Document Type and Number:
WIPO Patent Application WO/2016/123914
Kind Code:
A1
Abstract:
A method and equipment for slurry bed hydrogenation mixed refinement of oil and coal. The method comprises the following steps: first, coal powder, residue oil, and recycled wax are prepared into an oil-coal slurry; the oil-coal slurry, a catalyst, an additive, and hydrogen are mixed, passed through a preheater, and introduced into a slurry bed reactor for thermal cracking and hydrogenation reactions, and then all products are introduced into a hot high-pressure separator, where solids are separated at the bottom, and gases are separated at the top and then introduced into a fixed-bed reactor for further hydrocracking or refinement, a distillate oil produced is introduced into a fractionator tower, where wax at the tower bottom serves as recycled wax and recirculated to an oil-coal slurry preparation tank. The wax produced is reused as a coal-dissolving solvent, the viscosity of the oil-coal slurry is greatly reduced, the fluidity of the oil-coal slurry is improved, and the hydrogen donating capability of a liquid phase is increased. Only a media distributor is found within the slurry bed hydrogenation reactor, and no bed-level support plate is provided, thus greatly reducing medium pressure drop. The reactor has a moderate reaction pressure, the catalyst is inexpensive and easy to manufacture, for which only common domestic raw materials are used, thus greatly reducing costs.
