Note:
Removal of sulfur compounds from hot coal gas is a necessary step during power generation operations. Metal oxides as zinc ferrite, zinc titanate and tin oxide have been identified as promising adsorbents materials. A mathematical model capable of describing the sulfidation phase in fixed-, moving- and fluidized-bed reactors has been developed. Equations selected are sufficiently simple and numerical solutions can be obtaines in a reasonable time using available computer equipments. At the same the equations produce satisfactory agreement with experimental results. This paper presents kinetic models of spherical sorbent-particles applicable to all reactor configurations and a mathematical model limited to the moving-bed reactor. Key Words: Hot Gas Cleanup, Mathematical Models, Fixed-, Moving-, Fluidized-bed Reactors.
