Petroleum coke is one of common by-products of refineries,increasing the added value of petroleum coke is very important to the overall economic efficiency of the refinery.When petroleum coke is used as a graphite electrode,it is necessary to pay attention to the key indicators such as sulfur content,particle distribution,particle strength,tap density and resistivity of petroleum coke in time.In the production of petroleum coke used as a prebaking anode,it is necessary to reduce the solid particle content in the raw oil,and then reduce the trace element content in the petroleum coke,while paying attention to the density of petroleum coke,powder resistivity and particle strength of petroleum coke.In order to realize the high-value utilization of petroleum coke,researchers are also actively expanding the application scenarios of petroleum coke,modifying petroleum coke,and exploring its application in the fields of lithium-ion batteries and sodium-ion batteries.Oil refining companies need to actively adjust their concepts and try to use petroleum coke as the main target product.For graphite electrodes,prebaking anodes and anode materials,the raw material indicators should be strictly controlled and the production process should be adjusted in time to customize the production of high value-added petroleum coke.
