  • Patent number: 10376836
    Abstract: 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%.

  • Patent number: 9745263
    Abstract: The present invention relates to a novel use of magnetic iron oxide red Fe21.333O32 as a catalyst in oxidizing methanthiol to prepare dimethyl disulfide. The magnetic iron oxide red Fe21.333O32 according to the present invention has extremely high catalytic selectivity in catalyzing and oxidizing methanthiol to prepare dimethyl disulfide. The magnetic iron oxide red Fe21.333O32 is prepared with a carbonate and a ferrite as raw materials, has advantages of low cost and simple preparation process, and is suitable for industrial production.
