  • SAPO CATALYST FOR A HIGH PRESSURE MTO PROCESS
    Publication number: 20170166493
    Abstract: A process is presented for the conversion of oxygenates to olefins. The process utilizes a catalyst comprising a silicoaluminophosphate with an added basic metal oxide. The basic metal oxide modifies the selectivity to increase the yields of propylene and heavier olefins. The increase in heavier olefins are processed downstream to further increase propylene yields, and to generate a process stream comprising butylenes.

  • HIGH PRESSURE SWING FIXED-BED PROCESS WITH OPTIONAL ETHYLENE RECYCLE FOR HIGHLY SELECTIVE METHANOL TO OLEFINS CONVERSION
    Publication number: 20160168045
    Abstract: A process is presented for the production of light olefins. The process utilizes a SAPO-18 catalyst and is operated at an elevated pressure. The process generates higher concentrations of heavier olefins which can then be processed to generate light olefins. The processing of the heavier olefins can include metathesis reactions and olefin cracking processes.

  • Counter-current fluidized bed reactor for the dehydrogenation of olefins
    Patent number: 9150466
    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.

  • Method for quenching paraffin dehydrogenation reaction in counter-current reactor
    Patent number: 9040763
    Abstract: A process is presented for quenching a process stream in a paraffin dehydrogenation process. The process comprises cooling a propane dehydrogenation stream during the hot residence time after the process stream leaves the catalytic bed reactor section. The process includes cooling and compressing the product stream, taking a portion of the product stream and passing the portion of the product stream to the mix with the process stream as it leaves the catalytic bed reactor section.

  • CATALYST MOISTURE SENSITIVTY MANAGEMENT
    Publication number: 20140364671
    Abstract: A method of regenerating spent dehydrogenation catalyst is described. The spent catalyst is heated to a regeneration temperature sufficient to remove coke and adsorbed water, and exposed to a purge gas at a purge temperature sufficient to remove water vapor surrounding the regenerated catalyst, the purged catalyst being maintained at the purge temperature. A method of dehydrogenating a hydrocarbon stream using the method of regenerating spent zirconia catalyst is also described.

  • For drying regenerated catalyst in route to a propane dehydrogenation reactor
    Patent number: 8603406
    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.
