The paper investigates the molding process of producing formed coke with low rank pulverized coal. When the bentonite as binder, the technological conditions mainly including bentonite content, forming pressure, forming moisture and particle size factors which effect on the strength of formed cokes were systematically discussed and obtained the optimal conditions. Under the conditions of amount of bentonite 5%, forming pressure 40kN, moisture content 14%, and fine coal particle size<5mm the formed coke with strength of 600N/ball was prepared and it satisfied the standard of gasification behavior of formed coke.
