Abstract

The invention discloses calcium acetate modified hydrophilia activated carbon and a preparation method thereof. The calcium acetate is loaded on the surface of the carbon skeleton of the activated carbon so as to form the hydrophilia activated carbon. According to the preparation method, the activated carbon raw material is treated sequentially through steps of processing at a high temperature, soaking in a calcium hydroxide solution, drying, and activating, then soaking in ethyl acetate, carrying out esterolysis reaction, nitrogen purging desorption, and vacuum desorption so as to prepare the hydrophilia activated carbon. The preparation method is simple to operate and has low cost; and the prepared hydrophilia activated carbon has a stable structure and large specific surface area, is low in carbon loss, can strongly adsorb vapour and has large adsorption capacity, has stable adsorption performance and has good reusability.

Description

technical field

[0001] The invention discloses calcium acetate-modified hydrophilic activated carbon and a preparation method thereof, in particular to the process of synthesizing hydrophilic organic functional groups on the surface of activated carbon by using organic reagents; it belongs to the field of catalytic modification. Background technique

[0002] Water vapor is one of the ubiquitous substances in nature. However, in some specific environments, such as precision instrument laboratories, warehouses, petroleum liquefied gas stations, etc., it is necessary to strictly control the content of water vapor to prevent major safety accidents caused by short circuits, corrosion, condensation, etc. with loss.

[0003] Adsorption is widely used because of its simple operation, easy recovery and avoidance of secondary pollution. Activated carbon has become one of the preferred adsorbents due to its developed pore structure, large specific surface area, abundant surface funct...
