Abstract

The invention discloses a preparation method of impregnated carbon for preventing acid / alkaline toxicants, solving the problems that the traditional carbon catalyst products prepared from compounds impregnated with Cu, Cr and Ag have poorer adsorption property to acid / alkaline toxicants, ammonia gas escaped in a use process seriously influences the body health of the staff so as to influence working efficiency, and the like. The preparation method comprises the steps of: preparing a solution, impregnating, calcining, sieving and mixing. By means of products produced with the preparation method disclosed by the invention, no ammonia gas escapes in the use process, toxicants such as the ammonia gas, sulfur dioxides and the like are catalyzed, benzene and other substances are physically adsorbed, and other harmful gases are removed.

Description

technical field [0001] The invention belongs to the field of impregnated carbon, and in particular relates to a preparation method of impregnated carbon for protecting acid and alkali poisons. Background technique [0002] At present, carbon catalysts impregnated with Cu, Cr, and Ag compounds on activated carbon are generally used to protect against acid and alkali poisons, such as Freon-12, benzene, xylene, acryl phenol, sulfur dioxide, hydrogen sulfide, ammonia, sulfuric acid mist , arsine, antimony and other toxic gases. Since the activated carbon is impregnated with Cu, Cr, and Ag compounds, the carbon catalyst is a catalyst product designed for the protection of hydrocyanic acid and hydrogen chloride, and has poor adsorption performance for the above-mentioned harmful gases. During use, the carbon catalyst product Ammonia gas can escape, seriously affecting the health of the personnel using the product and affecting work efficiency. Contents of the invention [0003...
