Problems solved by technology

Obviously, no matter whether anthracite with a high degree of coalification or lignite with a low degree of coalification, colloids required for coke formation cannot be formed during the pyrolysis process, only low molecular weight tar, low-carbon hydrocarbons, and CO, CO 2 、H 2 and other outputs, it is naturally impossible to produce high-strength lump coke

Embodiment 1

[0052] 9kg of mixed rubber powder made from waste tires, the mixed rubber powder is mainly composed of styrene-butadiene rubber, butadiene rubber, natural rubber and butyl rubber, and 1kg of spent catalyst activated clay powder below 200 meshes is uniformly mixed and then granulated on a granulator Granules, the particle diameter is no more than 3mm, preferably less than 1mm, and made into about 10kg of coking masterbatch (material), and 30kg of lean coal, fat coal, gas coal, 1 / 3 coking coal, and gas fat coal are selected respectively, and made into 40kg for coking. The raw materials are loaded into the small coke oven, operated according to the coking procedure, and then the finished coke is evaluated according to the GB4000-83 standard method.

Embodiment 2

[0054] 9kg of mixed rubber powder made from waste tires, 1kg of zinc ferrite catalyst (below 200 mesh, the same below), grind and granulate to make about 10kg of coking masterbatch, mix 30kg of lean coal with coking masterbatch, and tamp Coal blending was made after 10 minutes, and all the other were the same as in Example 1.

Embodiment 3

[0056] 9kg of mixed rubber powder made from waste tires, 1kg of iron oxide catalyst (below 200 mesh, the same below) for waste synthetic ammonia, ground and granulated to make masterbatch for coking, 30kg of fat-selected coal is mixed with coking masterbatch, pounded After solidifying for 10 minutes, make coking coal blending, and all the other are the same as in Example 1.

Abstract

The invention discloses a catalyzing cracking coking mother particle (material), which is characterized by the following: the mother particle (material) is composed of adhesive coking agent, catalyzing cracking catalyst, coke and non-coke coal, wherein the adhesive coking agent is self-waste plastic with resin, latex, industrial waste catalyst with iron and iron ore, which utilizes non-coke coal to produce regular coke with coking coal.

Description

technical field [0001] The invention relates to a bonding masterbatch for refining coke. Background technique [0002] Iron and steel production needs to consume a large amount of high-quality coke, and coke production requires a large amount of high-quality coking coal. The quality requirements of coking coal are special and demanding. Only coal with good cohesiveness and coking property can be used to produce high-quality coke. [0003] Coking coal is a kind of coal with medium or high degree of coalification in bituminous coal. It has medium or strong cohesiveness and can produce colloids with good thermal stability after heating. When coking a single coal, it can be Refined into coke with good melting, large lumps, few cracks, high strength and good wear resistance. Due to the limited and scattered coking coal resources and the difficulty in finding alternative resources, the price of coking coal remains high, especially high-quality coking coal. The shortage of cokin...
