Abstract

The invention discloses a raw material for producing carbon and graphite products by using aluminum electrolysis waste cathodes and a preparation method, which belongs to the technical field of metallurgy and coal chemical industry. Carbon and graphite products include aluminum anodes, aluminum cathodes, carbon electrodes, electrode pastes, carburizers, graphite electrodes, etc. The method is as follows: take 100 parts of waste cathodes and process high-temperature treatment to obtain carbon materials; take 10-70 parts of biomass waste and undergo high-temperature carbonization treatment to obtain bio-carbon materials; mix carbon materials, bio-carbon materials and 1-10 parts of biomass adhesives , After forming and drying, the carbon block product is obtained. Carbon block products can replace coke, calcined anthracite, calcined petroleum coke, graphite crushed, pitch coke. The invention realizes resource utilization of waste cathodes. By combining waste cathodes of aluminum electrolysis with biomass energy, biomass energy is effectively utilized, and non-renewable resources such as coke, petroleum coke, anthracite, and graphite fragments are saved. The materials are effectively utilized without secondary pollution.

Description

technical field [0001] The invention relates to a raw material for producing carbon and graphite products by using aluminum electrolysis waste cathodes and a preparation method, which belongs to the technical field of metallurgy and coal chemical industry. Background technique [0002] Agricultural and forestry waste, wood waste, poultry manure and waste in the production process of animal husbandry, straw and wood other than grain and fruit in the process of agricultural and forestry production, lignocellulose such as trees, leftovers of agricultural product processing industry, discarded fruit shells, Biomass materials such as waste residues from sugar crops are regarded as biomass wastes and are not well utilized, resulting in a waste of energy. [0003] The electrolytic aluminum waste tank lining is an inevitable solid waste in the electrolytic aluminum production process. The emission per ton of aluminum is 7.5-15kg. The fluoride content in the waste tank lining is usua...
