petroleum pitch coke

基本解释

Electrochemical intercalation of lithium into PAN based carbon fibers, petroleum coke, pitch coke and needle coke were studied by AC impedance method.
用交流阻抗法對PAN基碳纖維、石油焦、瀝青焦、針狀焦進行了嵌鋰過程的研究。
Selective oxidation of carbon anode in aluminum electrolysis caused by reactivity difference between pitch coke and petroleum coke is one of the main causes for excess carbon consumption.
鋁電解生産中，碳素陽極兩組分（石油焦和瀝青結焦）的活性差異帶來陽極的選擇性氧化，是造成碳素陽極過量消耗的主要原因之一。
Petroleum coke and coal pitch are still the principal raw materials of carbon anode though there is a quite great progress in the production technology, ratio of constituents and other aspects.
盡琯多年來炭陽極的生産工藝、成分配比等方麪都得到了很大發展，但其主要原料沒有改變，依然是石油焦和煤瀝青。
