Abstract

The invention relates to a novel active carbon, and a preparation method and applications thereof. The preparation method comprises following steps: 1) careful selection of a coconut shell raw material; 2) carbonization of an obtained raw material; 3) activation of a carbonization production; 4) smashing and sieving of an obtained activation product; 5) water washing or acid washing; and 6) subpackaging. High quality coconut shell is taken as a raw material; and the novel active carbon is obtained via deep activation and a unique technology, and is capable of removing gaseous pollutants and harmful repugnant substances in the indoor air, reducing pollution, and purifying the air. The novel active carbon can be applied to the field of toys for children, and can be used for filtering the air so as to avoid microorganism breeding and infectious diseases, maintaining the freshness of the air around children, improving immunity of infants and young children, helping infants and young children fall asleep, and avoiding skin itch and eczema.

Description

technical field [0001] The invention relates to the field of activated carbon production, in particular to a novel activated carbon and its preparation method and application. Background technique [0002] There are a large number of micropores invisible to the naked eye in activated carbon materials. The micropores in 1 gram of activated carbon materials can reach a surface area of ​​800-3000 square meters after being expanded, and even higher for special purposes. It is these highly developed pore structures like human capillaries that enable activated carbon to have excellent adsorption properties. The existing activated carbon preparation method using waste materials is not mature, and the activated carbon is used to manufacture Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of activated carbon preparation method, which has a simple preparation process and easy material selection, and uses waste ...
