DESULFURIZATION TESTS OF ZnO NANO-STRUCTURES PREPARED BY MATRIX ASSISTED METHOD FOR ULTRA CLEANUP OF COAL DERIVED GAS
IntroductionZinc oxide is considered as an excellent candidate for electro and electro-optical device, such as piezoelectric device, transparent electrodes, blue-violet optical emission devices and catalysts. The size and shapes of ZnO nano particles depend on the method of preparation, such as chemical vapor deposition (CVD), electro deposition, vapor phase transport, thermal evaporation using ZnO powder, etc.. A nano-size ZnO was synthesized by a matrix-assisted method and a study on the synthesized ZnO was performed to figure out new possible application to the hot gas desulfurization (HGD) process in the integrated gasification combined cycle (1GCC) power plant. Sorbents for an ultra gas cleaning in HGD is required to have not only a fast reaction rate in a gas-solid phase reaction but also a high sulfur capacity in order to reduce a low concentration of sulfur compounds (H2S, COS) contained in a gasified fuel gas from 50 ppmv to 60 ppbv. Sorbents should have a high surface area to meet this requirement.
