Novel formed active carbon and preparation method thereof

Abstract

The invention provides novel formed active carbon, which is prepared from the following raw materials in parts by weight: 30-400 parts of activated carbon, 30-300 parts of a curing material and 20-1200 parts of water, wherein the curing material is prepared through high-temperature calcination of the following raw materials in percentage by weight: 40-80% of CaO and 20-50% of SiO2, or 20-95% of Al2O3 and 5-80% of CaO, or 40-80% of CaO, 20-60% of SiO2 and 20-60% of Al2O3. The activated carbon can be freely formed, the adsorption capacity of the activated carbon can be reserved to the maximal extent after the activated carbon is formed; the molded product is high in adsorption capacity, high in adsorbing capacity and high in strength, and can be applied to the industries of odor removal, purification, building materials, decoration and health preservation; meanwhile, repeated activation use can be very conveniently carried out; activated carbon production can be carried out by adopting industrial and agricultural wastes; and the novel formed active carbon is more energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of activated carbon, in particular to a novel shaped activated carbon and a preparation method thereof. Background technique [0002] Harmful substances in indoor air include formaldehyde, benzene, ammonia, smoke, etc., and the damage caused by indoor air pollution to the human body cannot be ignored. According to relevant surveys, 72% of households in China have unqualified indoor air quality, and 111,000 people die each year due to indoor air pollution, reaching 304 people every day. The peculiar smell of the object cannot be ignored. [0003] In addition, water pollution incidents have occurred frequently in recent years. Since social production and life are closely related to water, sewage treatment is also an urgent problem to be solved in today's society. [0004] Activated carbon is a carbonaceous adsorption functional material composed of microcrystalline carbon and amorphous carbon arranged in a "...
