Abstract: 3 Longyan anthracites with different lithotypes were separated by flotation technique. Their proximate analysis, ultimate analysis and petrographical analysis were conducted. Their particle properties, such as surface figure and pore structure, were also examined by mercury porosimeter combining with SEM technology; further, the combustion characteristics such as ignition/burnout temperature and reactivity were studied using TGA. It is shown that most of macerals of Longyan anthracite are composed of vitrinite. For clarain, which has a relatively lower density, an extremely low volatile, and a higher fixed carbon content (> 80%), the primary maceral is vitrinite. For durain, which has an extremely high density (>2.0g/ cm3) and low carbon content, on the contrary, most of its maceral is mineral matter whose property is similar to that of coal gangue. Contrasted with the other two lithotypes, culm has the highest content of inertinite and its proximate and ultimate analysis is close to that of parent coal. Longyan anthracite has a very compact particle structure and has a density greater than 1.6g/cm3, the pores in particle are generally smaller than 1μm. The surface of clarain particle is glabrous and compact, most diameter of inner pore is between 0.01μm and 0.10μm, few has a diameter greater than 1μm. For clarain, the particle has a big specific surface area. The pore of durain particle is relatively developed, pore in the surface of durain particle can be seen from SEM; all the kinds of pore whose d>1μm，d=0.1μm~1.0μm，d=0.01μm~0.10μm and d<0.01μm exist in a particle. As to the culm, the pore in particle is few and undeveloped, most pore diameter in particle is smaller than 0.01μm. The ignition temperature of Longyan coal with different lithotypes is close to each other, nearly at 580℃. But there is great difference among their burnout temperature. The clarain has the highest burnout temperature while the durain has the lowest, the discrepancy between them is greater than 120℃. Judged from the specific maximum weight loss rate, which is defined as the quotient of the maximum weight loss rate in TGA to the corresponding sample′s fixed carbon content (daf), the reactivity of Longyan coal with different lithotypes can be ranked as clarain, coal, culm, and durain, from high to low.
