This standard specifies the chemical composition analysis method for nickel-based gas-phase benzene hydrogenation catalysts that use benzene or benzene-containing organic matter as raw material to produce cyclohexane. This standard is applicable to the determination of moisture (HO), nickel (Ni), aluminum oxide (Al O), potassium oxide (KO) and loss on ignition mass fraction in nickel-based gas-phase benzene hydrogenation catalysts.
