摘要
中国石油化工股份有限公司齐鲁分公司开发了高性能LC-02碳基吸附剂,并对吸附剂进行了性能评价。以活性炭作为载体原料,采用挤出成型法制备了LC-02吸附剂,吸附剂制备工艺合理,重复性好。对LC-02吸附剂进行了详细的物化性能表征,LC-02吸附剂比表面积大于1000 m^(2)/g、孔体积大于0.7 mL/g,具有较多的碱性中心和丰富的表面官能团。考察了不同反应温度、反应空速、SO_(2)浓度对吸附剂性能的影响,在温度150℃、体积空速2500 h^(-1)、O_(2)的体积分数为3%、SO_(2)的体积分数为35~1000μL/L条件下,吸附剂穿透硫容可达22.0%以上,可以满足工业装置应用要求。考察了吸附剂再生性能,适宜的再生温度为350~380℃,吸附剂再生10次硫容保留率达90.2%,吸附剂易于再生并且具有良好的再生稳定性。
This article introduces the development process of high-performance LC-02 carbon based adsorbent by SINOPEC Qilu Petrochemical Company,and evaluates the performance of the adsorbent.LC-02 high-performance carbon based adsorbent was prepared by extrusion molding using activated carbon as the carrier material.The adsorbent preparation process was reasonable and had good repeatability;Detailed physicochemical performance characterization was conducted on LC-02 adsorbent,which has a specific surface area greater than 1,000 m^(2)/g and a pore volume greater than 0.7 mL/g,with numerous alkaline centers and abundant surface functional groups;The effects of different reaction temperatures,reaction space velocity,and SO_(2)concentrations on the performance of the adsorbent were investigated.Under the conditions of temperature of 150℃,volume space velocity of 2,500 h^(-1),volume fraction of O_(2)of 3%,and volume fraction of SO_(2)of 35-1,000μL/L,the sulfur penetration capacity of the adsorbent can reach over 22.0%,which can meet the requirements of industrial equipment use;The regeneration performance of the adsorbent was investigated,and the suitable regeneration temperature was 350-380℃.The sulfur capacity retention rate of the adsorbent after regenerated 10 times reached 90.2%.The adsorbent is easy to regenerate and has good regeneration stability.
