实验室快速评价催化裂化油浆阻垢剂的方法

摘要

A method for fast evaluating the performance of FCC slurry antifoulant in laboratory is introduced. Using an autoclave with stirring, the suitable test conditions are obtained by orthogonal tests as follows:an antifoulant added amount of 100 mg/L, heat to 500 ℃ and hold for 4 h. The test results obtained by this modified static evaluation method are compared with those from the dynamic simulation method, and their trends of ranging antifoulants by fouling inhibited rates are-in good agreement, which indicates that this method could be used to fast evaluate slurry antifoulant in laboratory.%研究了实验室快速评价催化裂化油浆阻垢剂的方法,采用带搅拌的高压釜,根据正交试验得到的适宜试验条件为:加热温度500℃,加热时间4h,阻垢剂加入量100 mg/L.结果表明,用该方法得到的阻垢剂阻垢率趋势与动态法得到的结果一致.改进的静态评价方法可作为实验室快速评价油浆阻垢剂的方法.
