Problems solved by technology

[0002] At present, there are many kinds of adsorption catalysts for hydrogen sulfide removal. The better catalyst for hydrogen sulfide removal is composite iron, which can achieve a desulfurization effect of less than 5ppm, but the effect is better when the hydrogen sulfide content is low, and the sulfur capacity can reach 20. % or more, but its sulfur capacity is less than 10% for high hydrogen sulfide gas

Embodiment Construction

[0012] The invention relates to a preparation method of an attapulgite clay desulfurization adsorption catalyst. The attapulgite clay is used as a raw material, and composite iron, pyrolusite and water are added, stirred, extruded, and then activated by roasting. The main components of composite iron are ferric hydroxide and carbonate, and the rest are impurities. The main component of pyrolusite is manganese oxide. Attapulgite clay has a purity of 93%.

[0013] The specific steps of the preparation method are:

[0014] (1) Select attapulgite clay and add not less than 10% by weight;

[0015] (2) The weight of adding composite iron is not less than 10%, and the weight of pyrolusite is not less than 10%;

[0016] (3) add water and stir, the content of water is not less than 10%; Remove the weight of composite iron, pyrolusite, water, all the other are the weight of attapulgite clay;

[0017] (4) extrusion molding, the size is 5mm in diameter and 12mm in length;

[0018] (5...

Abstract

Relating to preparation methods of solid adsorbent catalysts, the invention provides a preparation method of an attapulgite clay desulfurization adsorption catalyst. The method includes: taking attapulgite clay as the raw material, adding composite iron, pyrolusite and water, performing stirring, then conducting extrusion molding, and then carrying out roasting activation.

Description

technical field [0001] The invention relates to a method for preparing and activating a solid adsorbent composition, in particular to a method for preparing a catalyst with clay. Background technique [0002] At present, there are many kinds of adsorption catalysts for hydrogen sulfide removal. The better catalyst for hydrogen sulfide removal is composite iron, which can achieve a desulfurization effect of less than 5ppm, but the effect is better when the hydrogen sulfide content is low, and the sulfur capacity can reach 20. % or more, but its sulfur capacity is less than 10% for high hydrogen sulfide gas. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing an adsorption catalyst with higher adsorption capacity for hydrogen sulfide gas by using attapulgite clay. [0004] The invention relates to a preparation method of an attapulgite clay desulfurization adsorption catalyst. The attapulgite clay is used as a raw mat...
