Abstract
【解決手段】2つの再生段階(A)及び(B)を接続し、かつその上端が、前記第2段階の濃密相中の流動床直径の0.1〜1.5倍の、前記第2段階(B)の濃密相及び希薄相を隔てる界面(9)の上の距離で、第2段階(B)の希薄相に開口する上昇垂直導管(3)からなる2段階再生領域を含む、FCC装置からのヒューム中に含まれるNOxを減少させる装置である。
【選択図】 図1
Description
本発明によるNOxを減少させる装置は、二段階再生領域を有する流動床中で接触分解装置と共に使用でき、2つの段階は、実質的に垂直かつ細長い形状の管状導管によって接続され、該管状導管は、以下で単純に「垂直導管」と呼び、図1で参照番号(3)によって表す。
図2に示すような、単段階再生領域(A’)の記載は、二段階再生の場合の第1段階(A)の流動床の記載とほぼ同一である。
流入コークの流量:装入材料の質量流量の8.2%
触媒の流量:装入材料の質量流量の760%
流動化空気の流量:装入材料の質量流量の134%
垂直導管に導入される空気の流量(本発明による) 装入材料の質量流量の11%
再生温度:735℃
垂直導管に導入される空気の流動化空気に対する比は、0.083である。
