Abstract

A carbon monoxide adsorbent comprises the following raw materials, by weight: 38 to 42% of cuprous chloride, 18 to 23% of 13X molecular sieves, 8 to 10% of aluminium hydroxide, and 28 to 35% of purified attapulgite powder. The adsorbent is produced by the following steps: a. the 13X molecular sieves are baked in a 200 DEG C oven for 120 to 150 minutes; b. the four raw materials are mixed into a mixed material, which is put into a kneader, purified water, the weight of which is 10% of that of the mixed material, is added into the kneader for kneading for 20 to 25 minutes, and kneaded material is obtained; c. the kneaded material is then processed by an strip extruder into strip-shaped objects with sizes between phi 3 mm * 8 mm and phi 3 mm * 15 mm; and d. the strip-shaped objects are put into the oven, baked at a temperature between 300 and 320 DEG C for 180 to 200 minutes, then taken out, and made into the carbon monoxide adsorbent after natural cooling. The carbon monoxide adsorbent is scientific in combination. Especially by adding 200 mesh purified attapulgite powder which undergoes crushing, purification, ultrafine processing and activation processing, the carbon monoxide adsorbent is improved in adsorption capability and substantially lowered in cost. The price of the carbon monoxide adsorbent is two thirds of those of similar products.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a carbon monoxide adsorbent. Background technique [0002] Carbon monoxide adsorbent is an important basic chemical raw material, which is widely used in chemical industry, petroleum, natural gas, as well as steel plants, power stations, metal mines, etc., especially in environmental protection, such as rescue cabins. The carbon monoxide adsorbent in the prior art has high cost and high price. Natural non-metallic mineral attapulgite, also known as palygorskite, has good adsorption effect. Contents of the invention [0003] The object of the present invention is to provide a carbon monoxide adsorbent with high adsorption performance and low cost. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a carbon monoxide adsorbent, characterized in that cuprous chloride, 13X molecular sieve, aluminum hydro...
