Abstract
Processes of catalytically pyrolyzing solid hydrocarbonaceous materials in a downflow fluid bed reactor and regenerating the catalyst in an upflow fluidized bed reactor are described. Systems and compositions useful in the catalytic pyrolysis of plastics are also described.
Claims32
A process for converting solid hydrocarbonaceous materials to useful products comprising:
- a) feeding solid hydrocarbonaceous materials into a fluidized bed catalytic pyrolysis reactor containing a solid conversion catalyst by means of a feed system that includes a particle distribution device that spreads feed particles over the surface of the bed,
- b) reacting the hydrocarbonaceous materials to form vapor products,
- c) withdrawing and recovering the vapor products, and
- d) recovering olefins, aromatics, or both, from the vapor products.

An apparatus for converting solid hydrocarbonaceous materials to useful products comprising:
- a) a feed hopper comprising solid hydrocarbonaceous materials comprising polymers or biomass or both,
- b) a fluidized bed catalytic pyrolysis reactor containing a conversion catalyst,
- c) a particle distribution device positioned to feed the solid hydrocarbonaceous materials into the fluidized bed catalytic pyrolysis reactor at a point in the reactor above the height of a dense bubbling phase of the fluid bed,
- d) a conduit adapted to feed hot regenerated catalyst at a point in the reactor above the height of the dense bubbling phase of the fluid bed,
- e) a conduit adapted to pass the vapors from the fluid bed into one or more cyclones in which entrained particles are removed,
- f) a conduit adapted to withdraw catalyst and solids from the catalytic reactor,
- g) a conduit adapted to feed used catalyst and any solids withdrawn from the catalytic reactor to a fluidized bed catalyst regenerator,
- h) a conduit adapted to withdraw hot, regenerated catalyst from the regenerator, and
- i) one or more cyclones through which the hot regenerated catalyst and combustion products can be passed to separate the solids.
