A production system for insoluble sulfur includes a polymeric kettle having a first discharge port and a quench tower () having a feed port. The first discharge port is in communication with the feed port. The quench tower has a cylindrical housing, a granulation device and a shear pump. A solvent inlet and a quenching agent inlet, which are respectively used for providing a solvent and a quenching agent, are arranged on the side wall of the housing. The sulfur production method includes raising the temperature of liquid sulfur under the protection of an initiator and nitrogen to perform polymerization reaction; introducing the polymerized material into the quenching tower and sequentially carrying out granulation and quenching treatment; carrying out solvent curing and extraction integrated treatment on the quenched product; and carrying out liquid phase circulating crushing and extraction integrated treatment on the cured and extracted product.

Production system and method for insoluble sulfur

A solid particle bed has a sea zone and at least one island zone distributed in the sea zone, and has an upper surface, a lower surface, an axial direction and a radial direction. The island zone extends along the axial direction of the solid particle bed but does not extend to the lower surface, and the voidage of the island zone is 110-300% of the voidage of the sea zone. In the solid particle bed, the oil preferentially enters the packing area with a small voidage through the tail section of the packing area with a large voidage. As the deposition amount increases, the oil gradually changes its way by entering the packing area with a small voidage through the side of the packing area with a large voidage.

Solid particle bed, fixed bed, and oil hydrogenation method

A hydrogenation catalyst contains a hydrogenation catalyst carrier and an active hydrogenation component. The active hydrogenation component includes a Group VIB metal sulfide and a Group VIII metal compound, and the molar proportion of a substance of the Group VIII metal compound that interacts with the Group VIB metal sulfide to the total amount of the Group VIII metal compound is 60-100%. The hydrogenation catalyst has a higher active metal sulfurizing degree and a higher number of type II active centers, and can be applied to the hydrogenation treatment process of oil products such as distillate oils and residual oils.
