摘要： Provided are a preparation method for insoluble sulfur and an anti-reversion stabilizer used thereby. Methane is used as the anti-reversion stabilizer. The methane is added to liquid sulfur at sulfur gasification stage, and is cracked into active free radicals under the action of sulfur vapor active free radicals; in the quenching process of sulfur vapor mixed with methane, the active free radicals generated by methane cracking carry out end capping on insoluble sulfur end groups generated by sulfur vapor polymerization, thus completing insoluble sulfur stabilization. The methane is added at liquid sulfur gasification stage, and after sulfur gasification, the methane is mixed with sulfur vapor in a gaseous form, rather than being added to the product in a solid or liquid manner at a later stage, so that the insoluble sulfur and the stabilizer can be uniformly contacted and mixed to the greatest extent.

摘要： The present invention relates to a method for the manufacture of cyclododecasulfur, a cyclic sulfur allotrope wherein the number of sulfur (S) atoms in the allotrope's homocyclic ring is 12. The method includes reacting a metallasulfur derivative with an oxidizing agent in a reaction zone to form a cyclododecasulfur-containing reaction mixture.

摘要： A process tank for producing insoluble sulfur comprising a tank body having an upper half portion, a lower half portion, a first end and a second end along the longitudinal axis; an inner semi-cylinder body inside the upper half portion; and a first filter plate in the lower half portion. The space between the inner semi-cylinder body and the tank body is a sandwich structure, and an inner cavity independent of the sandwich structure is provided inside the tank body. The first filter plate is wavelike in the cross section which separates from the inner cavity a first filter liquid cavity. A first liquid outlet communicating with the first filter liquid cavity is provided on the tank body.

摘要： The present invention relates to a method of transporting sulfur by pipeline with a minimum of sulfur precipitation and adherence to the internal parts of the pipeline system. By the present invention, the sulfur to be transported is formed into prills thereby reducing the static electricity charge accumulation capacity of the sulfur. The prills of sulfur are then formed into a pumpable slurry in a carrier liquid and the slurry is pumped through the pipeline.
