Requirements for dry desulfurization agents
Thread Content
The desulfurizer should contain active iron hydroxide, which is typically prepared by mixing ferruginous algae or iron shavings from metal processing with sawdust in a volume ratio of 1:1, adding 0.1% slaked lime to make the desulfurizer alkaline, and then moistening it evenly with water to achieve a moisture content of 30%–40%. The desulfurizer prepared from iron scrap needs to be exposed to the atmosphere for about 3 months, with regular turning over to ensure thorough oxidation.
