Problems solved by technology

The national conditions of ensuring the security of food supply determine that it is impossible to produce bio-liquid fuels based on crops. The most valuable for development and utilization is sorbifolium. At present, domestic scholars have done a lot of research on the preparation of biodiesel from radix sorbifolium, but there is no research on it. The research on the preparation of activated carbon from its husk, the main purpose of the present invention is to comprehensively develop and utilize my country's unique energy crop Xantho sorbifolium, through processing to make activated carbon, and to provide a very widely planted raw material for activated carbon

Abstract

The invention discloses a preparation method for activated carbon and a water purification filter element and a water purifier manufactured by the same. The preparation method comprises the followingsteps: (1) selecting shells; (2) pre-processing the shells; (3) dipping by zinc chloride; and (4) carbonizing and activating. The method is simple in process, convenient in operation, and low in costwithout consuming a lot of energy sources, and is capable of using xanthoceras sorbifolia bunge shells as a raw material, wherein the source of the raw material is extensive, and protecting the ecological environment. The prepared activated carbon is good in adsorption effect. The method is suitable for the agricultural field.

Description

technical field [0001] The invention belongs to the technical field of sorbifolia husks, and in particular relates to a preparation method of activated carbon and a water purification filter element and a water purifier prepared therefrom. Background technique [0002] Energy shortage and environmental pollution have become two major crises that threaten human existence. People are gradually devoting themselves to the research and development of environmentally friendly and renewable new energy sources, and seeking new materials and new processes to reduce environmental pollution. Activated carbon has developed micropores, high specific surface area, and strong adsorption capacity. It is an excellent adsorption material and is widely used in the fields of chemical industry, environmental protection, food and pharmaceuticals, catalyst carriers, and electrode materials. Activated carbon is usually prepared by physical activation and chemical activation, and its specific surfac...
