Coupling modified active carbon absorption desulfurizer and preparation method thereof

Abstract

A coupling modified active carbon absorption desulfurizer is composed of following raw materials in parts by weight: 70 to 80 parts of active carbon, 1 to 2 parts of silane coupling agent KH-550, 20 to 23 parts of aluminium hydroxide, 9 to 12 parts of apatite, 3 to 4 parts of phosphosiderite, 1 to 2 parts of bone glue, 8 to 10 parts of modified attapulgite, a right amount of hydrochloric acid with a concentration of 10 to 15%, and a right amount of water. The inorganic components in the desulfurizer such as active carbon and the like are coupled by the silane coupling agent KH-550 to form an elastic and flexible material, from which the active components are difficult to separate, the material can be applied to produce articles such as filtering screen, filtering membrane, and the like, and the application range of the active carbon absorber is enlarged. Furthermore the preparation method also adopts natural components such as apatite, phosphosiderite, and the like, reduces the middle production steps, saves the cost, and generates more economic profit.

Description

technical field [0001] The invention relates to a modification method of non-metallic ore, in particular to a coupling modified activated carbon adsorption desulfurizer and a preparation method thereof. Background technique [0002] With the development of science and technology and the gradual construction of modern industries, various chemicals have been developed and utilized, which has brought convenience to people's lives. The problem. [0003] At present, the pollutants in the air are mainly the gas produced by industrial fuel combustion, automobile exhaust, and toxic and harmful gases produced in production. Water pollution is mainly due to the fact that the sewage discharged from industrial production contains a large amount of toxic substances, and the sewage produced in people's daily life produces many harmful substances. There are many times in people’s lives that people need to remove toxins. For example, there are many bacteria and toxins on the filter screen...
