Abstract
A desulfurizing adsorption catalyst is prepared from attapulgite clay through adding composite Fe, pyrolusite and water, stirring, die pressing and calcining for activating it.
Description
Technical field
The present invention relates to preparation, the activation method of solid sorbent compositions, specifically is the method for preparing catalyst with clay.
Background technology
The adsoption catalyst of the depriving hydrogen sulphide that relates at present also has many kinds, use preferably that the catalyst of depriving hydrogen sulphide is compound iron, reach the following desulfurized effect of 5ppm, but effect is better when hydrogen sulfide content is low, Sulfur capacity reaches more than 20%, but to its Sulfur capacity of high hydrogen sulfide gas less than 10%.
Summary of the invention
The purpose of this invention is to provide with attapulgite clay prepare to hydrogen sulfide gas have more adsorption capacity the method for adsoption catalyst.
The present invention is Concave-convex clay rod desulfurization adsoption catalyst preparation method, is raw material with the Concave-convex clay rod, adds compound iron, pyrolusite and water, stirs, and calcination activation is carried out in extrusion modling then again, pulverizes at last.Concrete steps are:
(1) chooses Concave-convex clay rod, add weight and be not less than 10%;
(2) weight of the compound iron of adding is not less than 10%, and the weight of pyrolusite is not less than 10%;
(3) add entry and stir, the content of water is not less than 10%; Remove the weight of compound iron, pyrolusite, water, all the other are the weight of Concave-convex clay rod;
(4) extrusion modling is of a size of diameter 4～5mm, and length is 7～15mm;
(5) carried out roasting 0.5～3 hour at 200～400 ℃.
Compound iron main component is iron hydroxide and carbonate, and the main component of pyrolusite is a manganese oxide.
Usefulness of the present invention is: owing to add compound iron, pyrolusite in attapulgite clay, avoid appearing at the course of reaction undercapacity and adsorb the not high problem of conversion ratio separately, improved the adsoption catalysis efficient of catalyst.Sulfur removal technology of the present invention is simple, is easy to operate and control, and the depriving hydrogen sulphide effect, the average sulfide hydrogen 2500ppm of unstripped gas can take off below the 5ppm, and raw material sulfide hydrogen fluctuation range is 50～5000ppm.
The specific embodiment
The present invention is Concave-convex clay rod desulfurization adsoption catalyst preparation method, is raw material with the Concave-convex clay rod, adds compound iron, pyrolusite and water, stirs, and calcination activation is carried out in extrusion modling then again.Compound iron main component is iron hydroxide and carbonate, and all the other are impurity.The main component of pyrolusite is a manganese oxide.The purity of Concave-convex clay rod is 93%.
Preparation method's concrete steps are:
(1) chooses Concave-convex clay rod, add weight and be not less than 10%;
(2) weight of the compound iron of adding is not less than 10%, and the weight of pyrolusite is not less than 10%;
(3) add entry and stir, the content of water is not less than 10%; Remove the weight of compound iron, pyrolusite, water, all the other are the weight of Concave-convex clay rod;
(4) extrusion modling is of a size of diameter 5mm, and length is 12mm;
(5) carried out roasting 3 hours at 200～400 ℃.
Claims (4)
1, Concave-convex clay rod desulfurization adsoption catalyst preparation method is characterized in that with the Concave-convex clay rod being raw material, adds compound iron, pyrolusite and water, stirs, and calcination activation is carried out in extrusion modling then again, pulverizes at last.
