Abstract:The coal petrography of 13 different rank single coals and the quality of cokes made on 40kg pilot coke oven were measured and analyzed in the paper. The results indicated that the relationship between optical texture index of coke (OTI) and vitrinite mean maximum reflectance of single coal was positive linear correlation; By multiple linear regression analysis, the quantitative relationship between vitrinite reflectance distribution and the component of coke optical texture were determined; The influence of composition of coke optical tissue on crushing strength for coke (M40) and coke reactivity index (CRI) can be observed: the more mosaics texture proportion of the optical tissue, the better of crushing strength for coke (M40) and its coke reactivity index (CRI).
