Example Embodiment

[0026] Example 1

[0027] (1) The sub-bituminous coal is crushed and mixed with additives to form a low-rank coal raw material for use;

[0028] (2) Use tamping equipment to tamping the crushed 1 / 3 coking coal to form a bottom layer of non-low-rank coal briquette; and continue adding the low-rank coal raw materials and 1 / 3 of the non-low-rank coal briquette to the bottom layer. Coking coal. In this process, 1 / 3 of the coking coal is added along the two ends of the coal loading box, that is, the 1 / 3 of the coking coal is filled with pulverized coal around the low-rank coal raw materials, and the above-mentioned coal raw materials are continuously tamped with tamping equipment Forming, forming a middle layer of briquette, and finally adding 1 / 3 of the coking coal to the middle layer of briquette for tamping forming to form the top layer of non-low-rank coal briquette and form the final raw material of briquette, that is, the middle part is the main body of low-rank coal briquette , ...

Abstract

The invention provides a moulded coal raw material suitable for low rank coal upgrading technology, the moulded coal raw material includes a low rank coal moulded coal body formed by low rank coal and an additive, the additive is an organic binder, air isolation destructive distillation weight loss of the organic binder at 850 DEG C is less than 50%; the moulded coal raw material also includes a non low rank moulded coal layer externally coating the low rank coal moulded coal body, the non low rank moulded coal layer is prepared from one or a plurality of medium rank coal, high rank coal or medium-high rank coal, and the adding amount of the low rank coal is 60-80wt% of the moulded coal raw material. The moulded coal raw material not only solves the problems of low using degree of a stamped coke oven and excess production capacity of coking industry in the prior art, and solves the problems of restricted application due to no large-scale industrial equipment in view of the low rank coal, after the additive is mixed with the low rank coal, effective components in the additive contribute to degradation of polymer in low rank coal at high temperature and fracture of polymer in the low rank coal so as to improve the oil and gas yield in technical process.

Description

technical field [0001] The invention relates to a coal raw material suitable for a low-rank coal upgrading process, in particular to a molded coal raw material for a low-rank coal upgrading process using an existing tamping 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 conte...
