Abstract

The present invention provides coking process raw materials, which comprise low-rank coal and an auxiliary agent, wherein the auxiliary agent is an organic binder with air isolated dry distillation weightlessness of less than 50% at a temperature of 850 DEG C, and preferably the organic binder is asphaltene with a softening point of more than 100 DEG C. According to the present invention, with the raw materials, the problems of low existing stamp-charging coke oven utilization rate and excess coking industry production capacity are solved, and the problem that the application of the low-rank coal is limited due to no large-scale industrial equipment is solved; and after the auxiliary agent and the low-rank coal are mixed, the degradation of the macromolecule polymer in the low-rank coal at the high temperature and the breaking of the macromolecule in the low-rank coal are easily achieved through the effective components in the auxiliary agent so as to improve the oil gas yield during the process, wherein the total amount of the oil gas is increased by more than or equal to 10%.

Description

technical field

[0001] The invention relates to a coal raw material used in a coking process, in particular to a coal raw material used in a coking process using an existing stamping furnace. Background technique

[0002] Coal is the main energy source in my country, accounting for about 70% of the primary energy structure. In the long process of geological evolution, the formation of coal is affected by many factors, resulting in various types of coal. According to the structure and composition, coal is divided into three categories: lignite, bituminous coal and anthracite. Bituminous coal is divided into low-metamorphic bituminous coal and medium-metamorphic bituminous coal. Low-metamorphic bituminous coal is also called sub-bituminous coal, which is collectively referred to as "low-rank coal" together with lignite. . Low-rank coal is the product of the initial stage of coalification. It has the characteristics of low carbon content, high moisture, easy pulverization, ea...
