摘要：

Optimization for hydrodenitrogenation (HDN) process conditions of coal tar in a trickle-bed hydrogenation unit were investigated using response surface methodology (RSM). The optimized process conditions were found as: reaction temperature of 704.4 K, hydrogen partial pressure of 13.48 MPa, hydrogen to oil volume ratio of 1600:1 and liquid hourly space velocity (LHSV) of 0.20 h(-1). The kinetics model for HDN of coal tar has been built. Experimental data were fitted by the Levenberg-Marquardt method.
