  • Publication number: 20140363343
    Abstract: Embodiments of apparatuses and methods for controlling heat for rapid thermal processing of carbonaceous material are provided herein. The apparatus comprises a reheater for containing a fluidized bubbling bed comprising an oxygen-containing gas, inorganic heat carrier particles, and char and for burning the char into ash to form heated inorganic particles. An inorganic particle cooler is in fluid communication with the reheater to receive a first portion of the heated inorganic particles. The inorganic particle cooler is configured to receive a cooling medium for indirect heat exchange with the first portion of the heated inorganic particles to form first partially-cooled heated inorganic particles that are fluidly communicated to the reheater and combined with a second portion of the heated inorganic particles to form second partially-cooled heated inorganic particles. A reactor is in fluid communication with the reheater to receive the second partially-cooled heated inorganic particles.

  • Publication number: 20140213428
    Abstract: One exemplary embodiment can be a process for stripping. The process can include passing catalyst to a stripping vessel containing a riser, providing a plurality of baffles having a first baffle and a second baffle, and providing one or more packing layers. The stripping vessel and riser may define an annular zone including annular area for stripping of the catalyst, and the first and second baffles collectively overlap in no more than about 50% of the annular area. Often, the first baffle is coupled to an outer circumference of the riser and extends outward, and the second baffle is coupled to an inner circumference of the stripping vessel and extends inward. Typically, the one or more packing layers are within the annular zone.

  • Publication number: 20140142362
    Abstract: A process and apparatus for the dehydrogenation of paraffins is presented. The process utilizes a reactor that includes a slower flow of catalyst through the reactor, with a counter current flow of gas through the catalyst bed. The catalyst is regenerated and distributed over the top of the catalyst bed, and travels through the bed with the aid of reactor internals to limit backmixing of the catalyst.
