Fcc catalyst attrition
WebDescription: Catalyst attrition in FCC units has been a long-standing challenge, now with renewed concern due to tightening regulation of microfine particulate emissions. Further, reducing catalyst fines can reduce operability problems elsewhere in the unit. WebTackling the Attrition Problem Industry demands a more attrition proof FCC catalyst wit hout sacrificing performance or yield structure In order to successfully design such a 4 catalyst, need to first understand how catalyst particles attrit in commercial units Identify the best lab method that accurately
