摘　　要：采用加氢裂化中试装置和中国石油化工股份有限公司抚顺石油化工研究院研制的高中油型加氢裂化催化剂,在加氢裂化试验装置进行了反应条件切换实验。利用db5小波对切换反应条件过程中各产品收率的变化进行了离散分析,研究了轻石脑油、重石脑油、中间馏分油和尾油产品收率在改变加氢裂化反应条件时的变化规律。结果表明:尾油一次通过向部分循环切换过程、尾油部分循环向全循环切换过程、空速由0.50 h^(-1)调节为0.67 h^(-1)过程和原料油切换过程中产品收率达到平衡所需时间依次为45,90,216,30 h。采用小波分析得出的加氢裂化反应各种条件切换过程趋势与实际相吻合。In a hydrocracking pilot plant, the middle distillate selective hydrocracking catalysts developed by Fushun Research Institute of Petroleum and Petrochemicals （FRIPP） were used for switching experiments. Changes of the products yield during condition switching have been analyzed by db5 wavelet time-frequency analysis. The variations of yields of light naphtha, heavy naphtha, middle distillate and tail oil in the change of hydrocracking reaction conditions are studied. The results show that switching from once-through operation to partly recycle, switching from partly recycle mode to total recycle mode, switching from the LHSV of 0.5 h^-1 to 0.67 h ^-1 and changing of feedstock need 45 hr, 90 hr, 216 hr and 30 hr respectively. The trend obtained by using wavelet analysis matches the practical results.
