The secondary raw material powder was prepared by the superfine powder petroleum coke that activated by acidic oxidant and coal tar pitch, which were then molded in different pressure for different holding time. After the roasting process, all the products reached the high flexural strength level. The product that was prepared with molding pressure at 200 MPa and holding time of 20 min, got the maximum flexural strength value of 53 MPa and compressive strength value of 108 MPa.
