Abstract

The invention relates to a pre-sulfuration device for a heavy oil hydrogenation catalyst and mainly aims at solving the problem that in the prior art, a hydrogenation catalyst is pre-sulfurized in a container, and consequently the pre-sulfuration effect is not good. The adopted pre-sulfuration device for the heavy oil hydrogenation catalyst comprises a computer control system, a sulfuration kettle, a temperature sensor and a pressure sensor. The sulfuration kettle has a stirring function, a kettle body is provided with a gas port and a discharging port, the top of the sulfuration kettle is provided with a rupture disk, a pressure gage and the pressure sensor, temperature measurement equipment is arranged in the kettle body and connected with the temperature sensor, and the lower portion of the kettle body is provided with a heating system. The computer control system is connected with the heating system, the temperature sensor and the pressure sensor through data lines or signals lines. According to the technical scheme, the problem that the pre-sulfuration effect is not good is well solved, and the pre-sulfuration device can be applied to pre-sulfuration of the heavy oil hydrogenation catalyst.

Description

technical field [0001] The invention relates to a presulfurization device of a heavy oil hydrogenation catalyst. Background technique [0002] Petroleum is a precious energy that is closely related to social development and human life. As crude oil becomes heavier and worse, the utilization rate of heavy oil becomes higher and higher. Petroleum distillate oil hydrotreating, especially the hydrotreating of heavy oil such as wax oil and residual oil, is related to the quality of oil products. At present, industrial oil hydrogenation catalysts use noble metals or non-noble metals as active components to disperse on supports with specific pore structures in the form of oxidation, and hydrogenation catalysts need to be presulfurized before use. [0003] The presulfurization of the hydrogenation catalyst usually adopts the presulfurization technology in the reactor, that is, the catalyst is loaded into the reactor, and then hydrogen and sulfide are fed into the reactor while the...
