Desulfurizer For Conversion And Absorption Of High-Concentration Carbonyl Sulfide And A Desulfurizer For Catalytic Conversion And Absorption Of Carbon Disulfide And Their Preparation Methods

摘要

Provided is a high-concentration carbonyl sulfide conversion-absorption type desulfurizer for use at medium-low temperature and preparation method thereof. The desulfurizer comprises 50%-75% magnetic iron oxide red (Fe21.333O32), 5%-10% alkali metal oxide (K2O), 5-35% anatase TiO2, and 5-10% shaping binder. The method of preparing the desulfurizer comprises: uniformly mixing a metatitanic acid prepared using ferrous sulfate recycled as a by-product from titanium dioxide production with K2CO3, calcining to activate at 500° C.-700° C., mixing with the magnetic iron oxide red and binder, roll molding at room temperature to form balls which are dried at 100° C.-150° C. to obtain the desulfurizer. The desulfurizer has a hydrolysis conversion of carbonyl sulfide higher than 99%, and has a higher sulfur capacity more than 25%.
