Abstract: Hydrocarbon feed to a catalytic reactor can be heat exchanged with flue gas from a catalyst regenerator. This innovation enables recovery of more energy from flue gas thus resulting in a lower flue gas discharge temperature. As a result, other hot hydrocarbon streams conventionally used to preheat hydrocarbon feed can now be used to generate more high pressure steam.

Abstract: Char-handling processes for controlling overall heat balance, ash accumulation, and afterburn in a reheater are provided. Carbonaceous biomass feedstock is pyrolyzed using a heat transfer medium forming pyrolysis products and a spent heat transfer medium. The spent heat transfer medium is separated into segregated char and char-depleted spent heat transfer medium. The char-depleted spent heat transfer medium is introduced into a dense bed of heat transfer medium fluidized by a stream of oxygen-containing regeneration gas. All or a portion of the segregated char is combusted in the dense bed using the stream of oxygen-containing regeneration gas. A portion of the segregated char may be exported out of the pyrolysis system to control the overall heat balance and ash accumulation.

Abstract: An apparatus and process are presented for drying a catalyst in a reactor-regenerator system. The process includes a continuous operating system with catalyst circulating between a reactor and regenerator, and the catalyst is dried before returning the catalyst to the reactor. The process uses air that is split between the drying stage and the combustion stage without adding equipment outside of the regenerator, minimizing energy, capital cost, and space requirements.

Abstract: The present invention comprises a process for conversion of oxygenates to olefins comprising contacting within a reactor the oxygenates with a catalyst to produce light olefins and wherein the reactor comprises at least two zones, a first zone wherein gas circulates at a faster rate than a second zone wherein a gas circulates at a slower rate; and inserting a quantity of inert gas into the second zone to increase circulation of any materials located in said second zone. The invention prevents accumulation of undesirable by-products within stagnant zones within the reactor and reduces the amount of coke deposited on catalyst or on surfaces within these zones.
