Problems solved by technology

If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to humans and organisms
At present, a variety of ways to utilize fly ash have been developed, but most of them have complicated processes or low added value of products

Abstract

The invention discloses a method for producing ceramsite from an FCC waste catalyst. The main raw materials used in the method are the FCC waste catalyst, coal ash and petrochemical alkali waste neutralizing liquid. The method comprises the steps of treating the FCC waste catalyst with liquid alkali, uniformly mixing the treated FCC waste catalyst with coal ash, finally adding a proper amount of the petrochemical alkali waste neutralizing liquid in proportion, and carrying out processes of balling, drying and calcination, so as to obtain the ceramsite. The ceramsite is produced from waste of thermal power plants and petrochemical engineering enterprises, so that the waste treatment problem of the relevant enterprises is solved, and meanwhile, the ceramsite with reliable quality and high strength can be obtained.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a technical method for producing fly ash ceramsite by utilizing FCC waste catalyst. Background technique [0002] FCC waste catalyst is a deactivated catalyst produced in the process of petroleum catalytic cracking. It contains more heavy metals and volatile organic compounds. If it is disposed of randomly, it will not only cause great harm and pollution to the environment, but also cause resources. Big waste. According to reports, in 2015, my country's oil consumption reached about 585 million tons, and the production of waste refining catalysts also reached about 207,000 tons, while FCC waste catalysts accounted for 68.9% of the total amount of refining catalysts used. Its capacity is very large, if it is not disposed of properly, it will cause serious secondary pollution. In addition, the cost of disposal of the spent catalyst is high. Therefore, the comprehensive utili...
