Abstract: A regeneration method of a nitrogen-containing carbon catalyst includes the following steps: roasting the nitrogen-containing carbon catalyst in a nitrogen-containing atmosphere to obtain a regenerated nitrogen-containing carbon catalyst. The method is a universal method, which is suitable for nitrogen-doped carbon catalysts and can be used to regenerate a nitrogen-containing carbon catalyst for producing vinyl chloride (VC) through 1,2-dichloroethane cracking. The method can greatly reduce the production cost of the catalyst and increase the service life of the catalyst, and a regeneration process thereof is fast, simple, and controllable, and does not require high temperatures.

Abstract: Disclosed are preparation of zinc linolenate, and application thereof in preparing an anti-Helicobacter pylori drug. Zinc chloride is dissolved in sterile water, and the zinc chloride solution is heated and activated in a reactor kettle, and then naturally cooled to room temperature; 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride, N-hydroxysulfosuccinimide sodium salt and linolenic acid are dissolved in an EMS solvent and activated in nitrogen gas; the activated zinc chloride and the activated linolenic acid are heated and reacted, then left for standing after the reaction is finished; a dialysis bag is used to perform dialysis in pure water until the pure water is clear and transparent; and a vacuum freeze dryer is used to perform drying, and zinc linolenate is obtained. The present invention successfully prepares zinc linolenate, with high yield, and the zinc linolenate has a good Helicobacter pylori inhibiting effect.
