Abstract： Coking was carried out by use of coal blends with anthracite. The change in structure of microcrystals of coke was investigated according to coke XRD pattern and Scherrer’s equation. The results reveal that the addition of anthracite facilitates the growth of microcrystals and the increase of crystal parameters La, Lc and graphite degree, g. The pore structure of coke was measured by nitrogen adsorption. It was found that the micro pore volume, specific surface area and average pore diameter were markedly decreased by adding anthracite to coal blend. The fractal dimensions of coke were calculated according to FHH model. It was shown that there exists fractal structure network in coke, and moreover, fractal dimensions of coke is decreased and coke surface becomes smooth due to anthracite addition.
