| titleOfInvention | Antitoxic regeneration solution of deactivated SCR denitration catalyst, and preparation method thereof |
| abstract | The invention relates to an antitoxic regeneration solution of a deactivated SCR denitration catalyst, and a preparation method thereof. The antitoxic regeneration solution comprises an active replenisher, an antitoxic modification liquid, and an additive component. The active replenisher comprises ammonium metavanadate, ammonium tungstate, and acid liquid. The antitoxic modification liquid comprises germanium nitrate, ammonium molybdate tetrahydrate, and ammonium cerium nitrate. The additive component comprises a penetrating agent, a dispersing agent, and an adhesive. According to the invention, the prepared active replenisher, antitoxic modification liquid, and additive component are well mixed according to a certain weight ratio, such that an antitoxic regeneration solution is obtained. The solution and the preparation method provided by the invention have the advantages that: the deactivated catalyst is pickled, and active components are simultaneously replenished, such that catalyst denitrification efficiency is recovered to above 90%. With the existence of the antitoxic component, the antitoxic performance of the catalyst is substantially improved, such that catalyst arsenic, sulfur and alkali metal toxic effects can be effectively relieved, and service life of the catalyst after regeneration is prolonged. |
