【 摘 要 】

This paper describes an attempt to divide the total sulfur capacity into its contribution from zinc and iron using a pressurized-type thermobalance. The methodology to estimate the sulfur capacities corresponding to zinc and iron was applied to evaluate the variation in performance during multiple-cycle desulfurization. Primary objective of this paper is providing information on the stability of zinc-related sulfur capacity, which is essentially important to the sulfur removal performance at the concentration of the part-per-million level.
