Octane catalyst effects on FCC unit heat balance
Conference
·
OSTI ID:5145582
An FCC catalyst that increases cracked gasoline octane by 2 research numbers can be expected to increase the endothermic heat of cracking by 50 BTU per pound of feed and to reduce the catalytic coke making tendency by 10 relative percent. Commercial and laboratory data indicate that the heat of cracking increase is due to the ''recracking'' of gasoline to C/sub 4/ and lighter gas as well as the minimization of hydrogen transfer reactions. The coke reduction is also attributed to lower hydrogen transfer. These heat balance effects of octane catalysts can reduce regenerator temperature by 30/sup 0/F in a commercial FCC unit.
