Abstract

The invention relates to a method for producing coke through co-coking coal and waste / used phenolic plastics. The method for producing the coke through co-coking the coal and the waste / used phenolic plastics is characterized by comprising the following steps: (1) carrying out mixing and cooking on butadiene-acrylonitrile rubber and the waste / used phenolic plastics; (2) crushing treated plastics; (3) blending and crushing the treated plastics and matching coal; and (4) carrying out coking test on coal blend. According to the method for producing the coke through co-coking the coal and the waste / used phenolic plastics, disclosed by the invention, an effective method is provided for utilizing the waste / used phenolic plastics by co-charring butadiene-acrylonitrile rubber, the waste / used phenolic plastics and coking coal, the environmental pollution caused by the waste / used phenolic plastics is reduced, and meanwhile, part of replacing raw materials are provided for the shortage of coking coal resources, so that the method has very good economic and environmental benefits.

Description

technical field

[0001] The invention belongs to the technical field of high-temperature pyrolysis of coal into coke, comprehensive utilization of waste plastics and environmental protection, and specifically relates to a method for co-coking coal and waste phenolic plastics to produce coke. Background technique

[0002] Due to the rapid development of economic construction, the plastic industry has developed rapidly. The plastics after processing and production are increasing day by day. In 2010, the output of plastics in the world market exceeded 250 million tons. And my country has become a veritable plastic production, consumption and importing country. Due to the corrosion resistance, drug resistance and aging resistance of plastic itself, it exists in nature for a long time and is difficult to degrade, causing serious "white pollution". The "white pollution" produced by waste plastics is not only an environmental problem, but also a social problem. Environmental prote...
