摘要
介绍了JK 0 10型金属钝化剂在呼和浩特炼油厂重油催化裂化装置的使用情况 ,该装置所加工的原料镍含量高达 14～ 2 0 μg/g ,平衡催化剂镍含量达 15 0 0 0 μg/g以上。在使用该钝化剂后 ,干气中H2 体积分数由 5 6 .88%下降至 39.2 6 % ,H2 /CH4由 5 .33降至 2 .18,总轻收提高 1.2个百分点 。
commercial application of the JK 010 metal passivator in RFCCU of Huhehaote Refinery was introduced.The nickle contents in the feedftock and equilibriam catalyst are as high as 14～20 μg/g and 15 000 μg/g respectively.Using this passivator,the volumetric content of H 2 in dry gas decreased from 56.88% to 39.26%,while H 2/CH 4 ratio from 5.33 to 2.18 and the total light oil yield enhanced by 1.2%.
