Analysis and optimization of hydrocracking process conditions for the heavy fraction of medium temperature coal tar in a fixed-bed hydrogenation unit was investigated using single-factor tests and response surface methodology. The optimized process condition was found as： reaction pressure of 13.4 MPa, reaction temperature of 682 K, hydrogen to oil volume ratio of 1895：1 and liquid hourly space velocity of 0.30 h-1, under which the conversion rate of the heavy fraction of coal tar hydrogenation was 77%--78%.
