| 摘 要： | 从调节催化剂酸性或向反应体系外加抗氮剂的角度,介绍了加强催化裂化抗氮中毒能力,以增产汽油、柴油、丙烯或抑焦为目的的研究进展。针对于调变催化剂本身的酸性存在灵活性差、成本高的缺点,认为开发性优价廉的抗氮助剂改善原料质量,减缓催化剂中毒是有前景的抗氮中毒技术。

| Abstract: | The research was reviewed in this paper on controlling the products distribution of gasoline,diesel oil,propylene and coke by changing acidity of the FCC catalysts or adding additives to the feedstocks.Since the low agility and high cost of the commercial FCC catalysts were limited on controlling the acidity,developing additives of anti-nitrogen poisoning with good properties and low cost may be an effective approach. |
