Pulverized coal activator and coking coal prepared from same

Abstract

The invention provides a pulverized coal activator, which comprises the following components in percentage by weight: 1 to 14 percent of resin clay, 5 to 26 percent of glucose, 0.5 to 5 percent of cobalt molybdate, 0.5 to 29 percent of cholesterol ester benzoate, 1 to 29 percent of boron anhydrous, 1 to 15 percent of clay, 1 to 15 percent of titanium dioxide, 1 to 17 percent of sodium stearate, 1to 5 percent of ferric chloride, 1 to 10 percent of argil, 1 to 26 percent of anhydrous borax, 1 to 16 percent of modified starch , and 1 to 25 percent of tar residue. The pulverized coal activator added can be directly mixed with matched coal so as to ensure that active components and inert components of the matched coal can be easier to combine together during carbonization and raise the anisotropic tissue content of coke. The increase in coal fluidity is beneficial to intermediate phase for forming staged molecular rearrangement, promotes the transformation process of the intermediate phase, and forms higher-strength coke capable of replacing or partially replacing coking coal for coking. The pulverized coal activator has the advantages of small adding dose, high benefit and low comprehensive cost.

Description

Technical field [0001] The invention relates to the field of coking coal blending, in particular to a pulverized coal activator, and coking coal prepared from the pulverized coal activator. Background technique [0002] Coke is an important raw material and fuel for the metallurgical industry. With the rapid development of my country's iron and steel industry and the rapid growth of steel output, the demand for coke is increasing and the quality requirements are getting higher and higher. The quality of coke is severely restricted by the shortage of coking coal resources in my country. Therefore, it is very urgent to develop non-coking coal to replace or partially replace coking coal for coking, especially for my country and has important strategic significance. [0003] Although my country’s coal resources are abundant, there are not many types of coal suitable for coking, and the regional distribution of resources is extremely uneven. In particular, the reserves of high-quality ...

AI Technical Summary

Problems solved by technology

Existing activators are generally composed of water-soluble polymer compounds, surfactants, salts, etc. During application, some of them are sprayed into blended coal through aqueous solution, which will increase the water content of coal, which is not conducive to coking, and the blending The input is large, the cost is high, and the sulfur content is too high, which is not conducive to the improvement of coke quality
