简介:基于冷模型测试的结果,LPEC与新奇格子类型内幕在一个改革者为FCC催化剂的新生开发了一种技术以便加强在气体和固体之间的接触并且提高在regenerator.Testresults烧效率的焦炭表明了在与格子内幕装备的使流体化的床上的密度变化是相对同类的并且起泡的频率显然在邻近改革者墙的死了的使流体化的地区与明显的改进被减少,并且这台设备能在FCC改革者被用于催化剂的加强的新生。在在精炼厂A的0.8Mt/aRFCCU的这台设备的在工业上的应用显示了改革催化剂的碳含量从0.18%被归结为0.03%,并且烧的焦炭的数量被5%在改革者的烯释相节在改革者和某密度减小的主要的空中与明确的减小增加。
