铁氧化物的热特性研究

为了考查铁氧化物的常温脱硫活性,对制备的羟基氧化铁和氧化铁进行了热重分析,基本弄清了FeOOH和FexOy的热处理相变过程,为制备高活性、耐温变的低、中温气体脱硫剂打下了基础。 In order to examine the desulfurization activity of iron oxides at ambient temperature,the author did TG analysis on the prepared iron oxide hydroxides and iron oxides,and basically made clear the process of crystal phases transformation in heat treatment of FeOOH and FexOy,which is also helpful in preparing low and ambient temperature gas desulfurizer with high activity and with resistance to temperature changes
