| titleOfInvention | Montmorillonite and titanium dioxide composite carrier loaded active ingredient catalyst, preparation and application |
| abstract | The invention belongs to the field of preparation of new catalytic materials, and particularly relates to a montmorillonite titanium dioxide composite carrier loaded La/Ce efficient SCR denitration catalyst, and a preparation method and application thereof. The carrier in the catalyst is composite montmorillonite titanium dioxide, and the active ingredients are a main active ingredient and an auxiliary active ingredient, wherein the main active ingredient is lanthanum or cerium, the addition amount of the lanthanum or cerium is 0.1-50.0% of the total mass of the catalyst, the auxiliary active ingredient is one or more elements of manganese, iron, copper, tungsten, molybdenum, platinum and palladium, and the addition amount of the manganese, iron, copper, tungsten, molybdenum, platinum and palladium is 0-3.0% of the total mass of the catalyst; the ratio (mass) of the titanium dioxide to the montmorillonite in the composite carrier is 1:10-10: 1. The catalyst obtained by the invention can increase the specific surface area of a single montmorillonite carrier and the acid site content and strength of the single montmorillonite carrier. After active elements such as La, Ce and the like are uniformly loaded on the montmorillonite and titanium dioxide composite carrier, compared with a single carrier, NH is added 3 The SCR denitration activity is greatly improved. The catalyst has a space velocity of less than 400000h within a temperature window range of 250-500 DEG C ‑1 Under the condition, the NO conversion rate is basically stabilized to be more than 90.0 percent, and the method has wide application prospect. |
