    Gas Modified Pyrolysis Coke for in Situ Catalytic Cracking

    Modified pyrolysis coke can be used as a catalyst fortarcracking. In this paper, pyrolysis coke was used as a carrier for modification by using gases (H 2 O, CO 2, and NH 3), and the optimal modified gas was selected.On the basis of this, pyrolysis coke with different modifiedflowrates, temperatures, and times were prepared to catalyze the cracking oftar.
