A Method of Spray-Drying Zinc Oxide-Based Sorbents Applicable to Purification of Coal Gas

摘要

The present invention improves the shape, particle size and distribution, naemamodo, the desulfurization ability of the desulfurizing agent is applied in a fluid bed desulfurization process for removing sulfur impurities, hydrogen sulfide, etc., included in a fuel gas of high temperature and high pressure, such as coal gas that is used in the IGCC It relates to a molding method for producing spray-drying of the zinc-based desulfurizing agent for coal gas for purification.; The present invention comprising the steps of: preparing a desulfurizing agent material, comprising the steps of preparing a slurry, comprising the steps of: spray-drying the molding prepared from a slurry, a step of drying and firing the molding prepared desulfurizing agent unfamiliar delay, the playback enhancer on the fired desulfurizing agent and a step for producing a desulfurizing agent to the final loading and firing.
