The comparative test data of petroleum product test laboratories were processed by Robust Z method. The characteristics of frequency distribution of data of salfur contents in petroleum products are discussed.
The precaustic wash effect of solid base is examined in the laboratory simulation test, the results show that the life of gasoline sweetening catalyst is greatly increased after caustic wash by solid base SB-1, the caustic wash effect of solid base is same as that of caustic solution.
本文介绍了 S B- 1 固体碱的制备方法及其性能,并在实验室模拟工业装置上考察其预碱洗效果,结果表明:经 S B- 1 碱洗汽油脱臭催化剂寿命比未碱洗的大大增长,与液体碱洗效果相同,说明 S B- 1 固体碱能够代替液体碱预碱洗。
The effect of process condition on the glue and iodine value and nitrogen content of coking naphtha hydrotreating was studied in the laboratory by using uniform distribution and experimental design, and a mathematical model was established and the model was analysed.
The effects of aromatics content in mid pressure hydrotreating feedstock on reaction patterns, group chemical composition and viscosity indexes of the lube base oil products were studied in the laboratory with a Mid East VGO and its two furfural raffinate feeds.
