Abstract

The invention provides a preparation method of a hydrophobic molecular sieve runner. The preparation method comprises the following steps of: a runner rolling process, specifically, enabling first inorganic fiber paper and second inorganic fiber paper to pass through molecular sieve slurry at a constant speed, performing drying, and then impregnating the first inorganic fiber paper and the second inorganic fiber paper in inorganic glue, carrying out hot press molding on the first inorganic fiber paper to obtain corrugated paper, bonding the second inorganic fiber paper and the corrugated paper to form a honeycomb body, and drying the honeycomb body to obtain a primary runnerbody; an activation process, specifically, calcining the primary runner body in a high-temperature furnace for 1-8 hours, the calcining temperature being 200-800 DEG C; and runner processing and forming process, specifically, performing hydrophobic treatment on the primary runner body, and assembling to form the hydrophobic molecular sieve runner. The hydrophobic molecular sieve runner prepared according to the preparation method can be used for separating carbon dioxide.

Description

technical field [0001] The application relates to the field of environmental protection technology, in particular, to a hydrophobic molecular sieve runner for carbon dioxide separation and a preparation method. Background technique [0002] Carbon dioxide has been widely recycled in agriculture, industry, medical treatment and other fields, and the demand is gradually increasing. At the same time, the increase in the emission of carbon dioxide in the atmosphere, resulting in the greenhouse effect, has brought a huge crisis to the survival of the entire human being. Countries around the world are paying more and more attention to the problems caused by carbon dioxide. In the method of carbon dioxide separation, more and more attention is paid to the absorption and separation of carbon dioxide through molecular sieve runners, but the traditional molecular sieve runners tend to absorb moisture in the environment during the high-humidity absorption and separation process, result...
