Measurement of Sulfur Content of Coke on Used Catalyst with Coulomb Method

In viewing of the features of the used catalyst and the requirements to measurement accuracy of SOx in FCC regenerated flue gas,an experimental method is presented to measure sulfur content of coke on used catalyst with oxidization micro Coulomb method through study on sample preparation and experimental conditions such as tempera-ture and particle size of samples.Application shows that it is accurate and reliable.
