Properties of Ulug Khem Coal. 1. Types of vitrinite and its associations with microcomponents and minerals

Resumo

A review of research on Ulug Khem coal between 1951 and 2013 shows that its properties are largely determined by the plant material from which it is formed. This results in different types of vitrinite in Ulug Khem coal, with differences in clinkering properties, vitrinite reflectance, and yield of volatiles. Detailed petrographic analysis of coal from the Ulug bed in the Mezhegei deposit shows numerous associations of collinite with telinite and of telinite with bitumenite and also numerous associations of vitrinite with minerals. Thanks to the different properties of different types of vitrinite in Ulug Khem coal, the different associations of vitrinite with minerals, and the high ash basicity, coke produced from batch containing Ulug Khem coal will be characterized by low CSR and high CRI. That finding will be discussed in part 2.
