CATALYTIC CRACKING UNIT AND OPERATION

A mixing chamber for catalyst and oil in a catalytic cracking unit (2) in which atomized oil is introduced preferably axially in a preferably vertically oriented transfer line or riser reactor (7) from an atomization chamber (102) segregated from flow of cracking catalyst. The cracking catalyst flow...

Beschreibung
Zusammenfassung:	A mixing chamber for catalyst and oil in a catalytic cracking unit (2) in which atomized oil is introduced preferably axially in a preferably vertically oriented transfer line or riser reactor (7) from an atomization chamber (102) segregated from flow of cracking catalyst. The cracking catalyst flows with a radially inward component to the mouth of the riser (72) from the circumference thereof and mixes with the oil feed.
