Catalytic CO2 gasification of Qilu petroleum coke loaded with different black liquor concentrations（0—15%）was studied in the temperature range from 950℃ to 1200℃.The results show that the black liquor is of catalysis for petroleum coke gasification and can decrease remarkably its reaction activation energy.The rate of the catalytic gasification reaction can be well fitted by the shrinking-core model and their kinetic parameters are estimated.A study for rate constants of catalytic CO2 gasification reaction of Qilu petroleum coke using different black liquor concentration indicated that there exists kinetic compensation effect between pre-exponential factor and activation energy

and the isokinetic temperature is 1548 K.
