摘要： A temperature-controlling measure for a hydrogenation slurry bed reactor has three control points that are set from low to high: cold hydrogen is injected automatically when the system reaches control point 1; cold oil in injected automatically when the system reaches control point 2; each pressure relief is opened automatically when the system reaches control point 3. The pressure relief point is set before and/or after the circulation pump of the reactor if internal circulation is set in the reactor; the pressure relief point is set at the reactor bottom if the internal circulation is not set; at least one pressure relief valve is set at each pressure relief point.

摘要： An oil-coal co-hydrotreating processing includes the following steps: pulverized coal, vacuum residue and recycle oil are mixed to prepare coal slurry. After mixed with hydrogen, catalyst and additive, oil-coal slurry is preheated into a slurry bed reactor with high reacting pressure for thermal cracking and hydrogenation reaction. After reaction, all the products go into the hot high pressure separator for separation of solid from the bottom and gas from the top. The gas obtained goes into the fixed bed reactor for further hydrocracking or refining, and the distillate obtained enter the fractionating tower. The vacuum gas oil from the bottom of fractionating tower is taken as recycle oil piped to the oil-coal slurry mixing device as solvent.

摘要： A residue slurry bed hydrocracking method and device is used in the deep processing of crude oil. The processes of “slurry bed+fixed bed” reactor are applied. Raw materials, additives, catalysts and hydrogen are mixed, heated and pressurized before they are introduced into the slurry reactor, where thermal cracking and catalytic reactions occur under high hydrogen partial pressure. The coke, catalysts and additives in the reaction process are separated at the bottom of the heated high pressure separator (HHPS). Then they are transferred in a conventional fixed bed reactor to do further hydrocracking and hydrorefining, to product light oil products. The new Mo-Fe based catalyst developed in the invention can improve the activity of the main reactions, inhibit the reaction of coke production, and reduce system pressure from 20 Mpa to 17 Mpa, which can reduce device costs. Conversion rates can reach 90-95%, with the yield of light oil reaching 80-83%.
