Abstract: A riser includes a housing in communication with a entry conduit and an exit conduit. The housing is defined by a holdup chamber having a volume of between about 1133 liters and about 45307 liters. The riser is designed to receive a hydrocarbon feed and a catalyst. An apparatus for fluid catalytic cracking includes a riser in fluid communication with a reactor vessel. A hydrocarbon feed stream and a catalyst travel through a first section of the riser at a first velocity of between about 1.5 m/sec to about 10 m/sec and through a second section of the riser at a second velocity of more than about 15 m/sec. A process for fluid catalytic cracking uses a riser with a holdup chamber. A hydrocarbon feed and a catalyst decrease in velocity in the holdup chamber to between 1.5 m/sec and 10 m/sec.
