Embodiment Construction

[0020] Below in conjunction with embodiment the present invention will be further described,

[0021] 1. Ingredients mixing: The ingredients of montmorillonite natural gas desulfurizer are composed of the following components by weight percentage: 55% montmorillonite, 25% attapulgite clay, 12% aluminum oxide, 3% zinc oxide and 5% sodium hydroxide %.

[0022] 2. Sodiumization treatment: After stirring the above ingredients, put them into the soaking tank and add water to soak for sodiumization treatment. The sodiumization treatment time is controlled within 7 days.

[0023] 3. Extrusion and drying: Input the sodiumized ingredients into the screw extruder and extrude them into cylindrical strips. The diameter of the strips is controlled at 5 mm, and the length of the strips is controlled at 15 mm. The cement field is dried, and the moisture content of the mixture after drying is ≤15%.

[0024] 4. Roasting and cooling: put the sieved mixture particles into a roasting furnace fo...

Abstract

The invention discloses a montmorillonite natural gas desulfurizer, and the main points of the technical proposal are that the montmorillonite natural gas desulfurizer is composed of montmorillonite, attapulgite clay, alumina, zinc oxide and sodiumhydroxide. The preparing method is that the burden materials of the montmorillonite natural gas desulfurizer are input into a steeping cistern and then are steeped with water after mixed together to do sodium treatment, extrusion drying, separating by breaking and sieving, baking and packaging to be a finished product. The montmorillonite natural gas desulfurizer is a columniform strip granule, which generates chemical reaction after fully contacting with the nature gas to adsorb the sulfured and cyanide in the nature gas into the columniform strip granules to greatly reduce the content of sulfured in the nature gas and adsorb free water in the nature gas. The montmorillonite natural gas desulfurizer has a simple production process, a low cost and a great economic benefit and social benefit, and is acceptable for the desulfurizing process of nature gas, coal gas and marsh gas.

Description

Technical field: [0001] The invention relates to a desulfurizing agent, in particular to a montmorillonite natural gas desulfurizing agent. Background technique: [0002] Natural gas contains hydrogen sulfide, mercaptans, carbon dioxide, saturated water and other impurities. The existence of sulfide and cyanide in natural gas will cause corrosion of equipment and pipelines, cause poisoning and deactivation of chemical reaction catalysts, and directly affect the quality of final products. yield and quality. When it is used as a civil fuel, the sulfide in the exhaust gas will pollute the environment and endanger human health. Therefore, it is necessary to remove the harmful components in order to meet the requirements of factory production and civilian commercial gas. It is also necessary to remove free water in natural gas. [0003] At present, the desulfurization methods used in domestic natural gas mainly include wet process and dry process. Wet desulfurization refers to ...
