| PATENT CLAIMS |
Process for catalytically cracking a heavy hydrocarbon feed with particulate catalyst solids to selectively produce gasoline - Delivering the feed to the entrance of an upflow riser reactor - Delivering all of the particulate catalyst solids comprising a xeolite comp. in combination with an alumina matrix to the entrance of riser reactor at 1300-1600F & (catalyst solids)/ (feed) = 3-15 - Cracking hydrocarbon to cracked product gases at 800-1000F, pressure < 350 psig & hydrocarbon residence time 0.05-0.5 sec - Separating cracked prodt gases & catalyst in separator Whereby the selectivity to gasoline is improved over a process operating at a higher residence time & constant conversion |
