Abstract
An apparatus for cracking hydrocarbon with hot particulate solids wherein a curtain of hot particulate solids is delivered to a thermal reactor through peripheral openings and hydrocarbon feed is delivered to the reactor through the curtain of hot particulate solids at an angle.
Claims6
A cracking reactor comprising:
- (a) centrally offset orifices for delivery of particulate solids to the reactor;
- (b) at least two hydrocarbon feed inlet nozzles located in the reactor sidewall in the same plane;
- (c) a centrally disposed plug member in the reactor for the particulate solids to flow around upon entry into the reactor, the bottom of which plug member is at the elevation at which the hydrocarbon feed nozzles are located;
- and
- (d) a venturi shaped section between the solids orifices and the hydrocarbon feed inlets.
