Abstract
The invention discloses a catalyst for desulfurization treatment, which is formed by at least one element of praseodymium, lanthanum, cerium, nickel, zinc and titanium or a compound thereof and a catalyst carrier. The catalyst for desulfurization treatment provided by the invention, through utilizing various cooperated metals as active substances and taking activated carbon fibers with a high specific surface area as the carrier, has an excellent adsorption effect on the sulfur element in sulfur-containing substances such as flue gas and the like, so that the effect of the catalyst in the desulfurization treatment is obviously improved.
Description
Technical field
The present invention relates to a kind of environmental treatment engineering, especially a kind of catalyst for desulfurization process.
Background technology
Coal and oil are the main energy sources in industrial production and daily life, but it in use can produce certain oxysulfide, it is directly disposed in air can produce suitable pollution, so, in industrial processes, the flue gas that need produce above-mentioned fuel carries out desulfurization process; But, be difficult to reach perfect condition for the desulfurized effect of catalyst flue gas being carried out to desulfurization process in prior art.
Summary of the invention
the technical problem to be solved in the present invention is to provide a kind of catalyst for desulfurization process, and it effectively can improve the desulfurized effect of catalyst to sulphur-containing substance.
For solving the problems of the technologies described above, the present invention relates to a kind of catalyst for desulfurization process, it is by least one element in praseodymium, lanthanum, cerium, nickel, zinc, titanium or its compound, and catalyst carrier is formed.
As a modification of the present invention, the described catalyst for desulfurization process is formed according to its percentage by weight proportioning by following substances: praseodymium oxide 2% ~ 10%, nickel oxide 1% ~ 5%, titanium oxide 2% ~ 8% and zinc oxide 2% ~ 8%, surplus is catalyst carrier.
As a modification of the present invention, the described catalyst for desulfurization process is formed according to its percentage by weight proportioning by following substances: praseodymium oxide 4% ~ 12%, lanthana 2% ~ 6%, cerium oxide 1% ~ 11% and titanium oxide 1% ~ 11%, surplus is catalyst carrier.
