HIGH-CONCENTRATION CARBONYL SULFIDE CONVERSION-ABSORPTION TYPE DESULFURIZER AND CARBON DISULFIDE CONVERSION-ABSORPTION TYPE DESULFURIZER AND PREPARATION METHOD THEREOF

摘要

A High-concentration carbonyl sulfide conversion-absorption type desulfurizer and preparation method thereof at medium-low temperature, the desulfurizer consisting of: 50%-75% magnetic iron oxide red (Fe21.333O32), 5%-10% alkali metal oxide (K2O), 5-35% anatase (TiO2), and 5-10% shaping binder. Also disclosed is a method of preparing the desulfurizer: uniformly mixing the metatitanic acid recycled from the titanium white by-product ferrous sulfate with K2CO3, calcinating to activate at 5000C-7000C, mixing with the magnetic iron oxide red and the binder, rolling to shape at room temperature, and drying at 1000C -1500C. The desulfurizer provides more than 99% of hydrolysis conversion of carbonyl sulfide, with a high sulfur capacity of more than 25%.
