"SH/T 0026-1990 Petroleum coke Determination of Volatile Matter" is a standard on the technical method for the determination of volatile content in petroleum coke. The standard is applicable to the volatilization analysis of petroleum coke samples to evaluate their volatilization properties under high temperature conditions. The standard describes in detail the preparation and processing methods of the samples, the equipment used in the determination process and its operation steps, and the calculation method of volatile content. By implementing this standard, the volatile content in petroleum coke can be accurately determined, providing a scientific basis for the production, processing and trade of petroleum coke, and helping to ensure product mass and meet technical requirements.
