英文摘要： Scale of coke production in China is very huge, but the coking coal resources are limited. This project aims at studying the separation mechanism of low rank bituminous coals’ activity macerals and its utilization in coal blending for coking and establishing its mathematical model of coal blending, which has scientific value and theoretical significance for using low rank bituminous coals in coking. By means of studying maceral’s bonding characteristic and its separation mechanism of low rank bituminous coals based on their performance difference, effective separation method of low rank bituminous coals’ macerals will be formed. Heating-stage microscope is used to research the rheological property of low rank bituminous coals, at the same time activity macerals’ fluorescence properties, generation mechanism and analytical its molecular structure will be studied and indicated. Based on the above research, tests of coal blending with low rank bituminous coals will be carried out, finally low rank bituminous coals’ coking mechanism and blending mathematical model should be proposed. The objective of this project are revealing the activity maceral’s molecular structure, technological property and its separation mechanism from low rank bituminous coals, clarifying low rank bituminous coals’ coal blending coking mecha
