hydrogen sulfide, desulfurization, zinc oxide, kinetics, transient multiphase hydrodynamicsAbstract
Experiments with thermogravimetrical analyzer determined kinetic characteristics of clean zinc oxide (GOST 10262–73) and dynamic characteristics of Katalco 32-4 Johnson Matthey sorbent. Obtained data enable calculation of the sorbent volume required for a complete synthesis gas desulfurization, duration of sorbent working cycle, sorbent conversion rate and general kinetic characteristics of hydrogen sulfide absorption by zinc oxide. Chemical process simulation considering transient multiphase hydrodynamics resulted in the conversion rate of ZnO2SC oxide zinc with different isotherms and parameters of process involving pure zinc oxide and Katalco sorbent within 250 – 950 °C temperatures range.
