petroleum pitch coke

基本解釋

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(duì)PAN基碳纖維、石油焦、瀝青焦、針狀焦進(jìn)行了嵌鋰過(guò)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.
鋁電解生產(chǎn)中，碳素陽(yáng)極兩組分（石油焦和瀝青結(jié)焦）的活性差異帶來(lái)陽(yáng)極的選擇性氧化，是造成碳素陽(yáng)極過(guò)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.
盡管多年來(lái)炭陽(yáng)極的生產(chǎn)工藝、成分配比等方面都得到了很大發(fā)展，但其主要原料沒有改變，依然是石油焦和煤瀝青。
