Abstract

本发明涉及一种生产CO并减排的催化裂化方法，该催化裂化方法包括：(1)使得自催化裂化反应的积炭的待生催化剂经汽提后送入再生器，待生催化剂与再生气体在再生器中接触进行再生，经气固分离得再生催化剂和第一烟气；使部分第一烟气以循环比50～99％返回至再生器中；使至少部分再生催化剂循环用于催化裂化反应；(2)使未返回再生器的剩余的第一烟气进行旋风分离，得再生催化剂细粉和第二烟气；(3)使第二烟气进行换热，得第三烟气；(4)使第三烟气进行冷却，得第四烟气；(5)使第四烟气在CO分离单元中进行分离，得CO产品。本发明生产CO并减排的催化裂化方法使待生催化剂上的积炭以更高的CO选择性转化为烟气，同时降低CO分离能耗。
