摘要
针对目前国内炼油企业所加工的原料日益劣质化、重质化的问题,开发了鸟巢型加氢系列保护剂,并成功应用于加氢裂化装置。应用结果表明,对加工杂质含量高的蜡油原料,鸟巢型保护剂具有容垢和拦截杂质能力强的特点,可以实现杂质在保护剂床层上的均匀沉积,达到延长运转周期的目的,可为国内其它同类装置平稳生产提供经验与参考依据。
A series of nest form hydrogenation guard catalysts were developed as the feedstocks become worse and heavier in refineries and successfully applied in a commercial hydrocracking unit. The results show that the guard catalysts are characterized by larger capacity for intercepting impurity and depositing scale. The impurities are deposited uniformly in the guard catalyst bed, resulting in extended cycle length.
