Abstract

The invention relates to a low-carbon high-hydrogen coal dust modifier and a coal blending coking method. The modifier comprises the following components in percentage by mass: 60 to 85% of boric acid, 1 to 20% of adipic acid or dodecanedioic acid or alanine or the mixture of two or three of the adipic acid and dodecanedioic acid and alanine, 1 to 25% of calcium propionate, and 1 to 20% of seconary alkane sulphonate sodium or potassium stearate or stearic calcium lactate or the mixture of two or three of the seconary alkane sulphonate sodium and potassium stearate and stearic calcium lactate. The coal blending coking method comprises the following steps: weighing 0.01 to 1%of coal dust modifier and 0.1 to 5.5% of low-carbon high-hydrogen coal dust according to the mass of the coking fitting coal; transferring the coal dust modifier and the low-carbon high-hydrogen coal dust into a modifying device for modifying; uniformly mixing and placing the modified coal and 45 to 99% of coking coal into a coke oven; and then preparing high-quality carbon according to the conventional production process. The coal blending coking method has the advantages that the mass percentage of the low-carbon high-hydrogen coal dust in the coking fitting coal can be improved, the coking cost is greatly reduced, and remarkable economic benefits are brought.

Description

Technical field [0001] The present invention is the field of coal processing technology, which involves a low -carbon high -hydrogen coal molic agent and coal distribution method. Background technique [0002] With the rapid development of my country's steel industry, domestic coke coking coal is far from meeting the needs of the development of the metallurgical industry. The contradiction between the quality requirements of coke and the increasingly high and the coal quality is increasingly prominent. The development of non -converter coal refining is one of the important ways to expand coking coal resources.Among my country's coal resources, low -quality high -hydrogen -high -hydrogen coal, non -stick coal and weak sticky coal with low deterioration, rich reserves, wide distributed areas, cheap prices, but due to its low degree of deterioration, oxygen -containing functional groups Multi -, hydrogen bonds have high intensity, poor adhesion performance, high scorching expansion,...
