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.
用交流阻抗法对PAN基碳纤维、石油焦、沥青焦、针状焦进行了嵌锂过程的研究。
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.
铝电解生产中，碳素阳极两组分（石油焦和沥青结焦）的活性差异带来阳极的选择性氧化，是造成碳素阳极过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.
尽管多年来炭阳极的生产工艺、成分配比等方面都得到了很大发展，但其主要原料没有改变，依然是石油焦和煤沥青。
