Standpipe distributor for short time contact of hydrocarbon compounds with particles

A method for the conversion of hydrocarbons by injecting a substantially linear array of jets comprising an at least partial liquid phase hydrocarbon compound into a stream of fluidized particles, the method comprising:

• a) passing a fluidized stream of particles downwardly in a confined conduit having an angle of from 30 to 90 degrees with the horizontal axis to a junction point where the slope of the conduit decreases to an angle of from 0 to 45 degrees with the horizontal;
• b) restricting flow at the junction point with a horizontally extended portion of a fluid injector to create a flow restriction between the top of the conduit junction and the top of the feed injector;
• c) confining the particles with the flow restriction to create a horizontally extended layer of fluidized particles flowing through the conduit that extends horizontally across at least half of the inside diameter of the conduit;
• d) injecting the fluid jet comprising the hydrocarbon compound from the front face of the fluid injector that extends across at least half the horizontal width of the extended layer of particles in a principally transverse direction into the extended layer of particles;
• e) at least partially vaporizing the hydrocarbon compound by contact with the particles;
• and
• f) separating a mixture of vaporized hydrocarbon compound and particles to recover a gaseous product stream and contacted particles.

A method for the conversion of hydrocarbons by injecting a substantially linear array of feed jets comprising an at least partially liquid phase hydrocarbon compound into a stream of fluidized particles, the method comprising:

• a) passing a fluidized stream of particles downwardly in a confined conduit having an angle of from 30 to 60 degrees with the horizontal axis into contact with a horizontally extended flow restriction located in the top of the conduit;
• b) confining the particles with the horizontal flow restriction to create a horizontally extended layer of fluidized particles flowing through the conduit that extends horizontally across at least half of the inside diameter of the conduit;
• c) injecting a feed jet from the horizontal flow restrictor that extends across at least half the horizontal width of the extended layer of particles in a principally downward direction into the extended layer of particles;
• and
• d) at least partially vaporizing the hydrocarbon compound by contact with the particles;
• and,
