Abstract:
Petroleum coke is a solid product produced by delayed coking unit. Because of the characteristics of stability, low ash, low volatile, high carbon, high sulfur and high heating value, petroleum coke is widely used as raw materials for electrodes or chemical products in metallurgy, chemical industry and other industries. In 2017, the capacity of domestic delayed coking unit was 128.8×10
6 t/a, the petroleum coke yield was 27.217×10
6 t (increased cumulatively by 3.5%). The yield, distribution of locations, and downstream application of petroleum coke in China were reviewed. Combined with the challenge of petroleum coke market with the upgrading of environmental protection requirements, the outlet of high sulfur-containing petroleum coke was considered from material control, technology improvement and downstream market development. The research progress of boiler fuel, electrode material, preparation of activated carbon material, petroleum coke gas making, utilization of petroleum coke ash were mainly discussed. The utilization and development of petroleum coke were predicted and prospected.
