ActiveCarbonaceous materials used in the production of aluminium―Pitch for electrodes―Part 13：Determination of C/H ratio in the quinoline-insoluble fraction
原铝生产用炭素材料 煤沥青 第13部分：喹啉不溶物中C/H原子比的测定
Application Summary AI generated
This standard specifies a method for determining the carbon-to-hydrogen (C/H) atomic ratio specifically within the quinoline-insoluble fraction of coal tar pitch. It is applied in the aluminium smelting industry to characterize the quality and structural properties of electrode pitch, which is used as a binder in carbon anodes for electrolytic reduction cells. The C/H ratio measurement helps predict the pitch's coking behavior and final anode performance during the aluminium production process.
