Abstract: A process of oxidative dehydrogenation in a fluidized riser reactor is described. Hydrocarbon feed and catalyst are fed to the bottom of the fluidized riser reactor. Part of the hydrogen produced in the dehydrogenation reaction is oxidized using oxygen introduced into the riser reactor through oxygen injection ports to produce the heat required for the dehydrogenation reaction.

Abstract: A process is presented for generating light olefins with the methanol to olefins process from a combination of catalysts. The process controls the product distribution for ethylene, propylene and butylenes, to enable shifting of the product distribution. The process includes passing a second catalyst to a reactor while the process is on-going.

Abstract: A process is presented for the dehydrogenation of paraffins. The process utilizes the combustion of a fuel within the dehydrogenation reactor to provide the heat of reaction for dehydrogenation. The process controls the combustion through limiting the oxidant concentration. A paraffin feedstream is mixed with a fuel, and the fuel/paraffin feedstream is mixed with an oxidant stream at the inlet of each dehydrogenation reactor.

Abstract: Processes and apparatuses for the production of propylene are provided. In an embodiment, a process is provided for production of propylene from an oxygenate feed comprising passing the oxygenate feed to an oxygenate-to-olefin reactor to contact the oxygenate feed with a catalyst to provide an effluent stream comprising olefins comprising ethylene, propylene and butylene. The effluent stream is separated in a product separation zone to generate a propylene product stream, an ethylene stream and a C4+ stream. The ethylene stream is reacted in an ethylene dimerization or oligomerization reactor in presence of a dimerization or oligomerization catalyst to provide a first process stream. The C4+ stream and the first process stream are cracked in a cracking reactor under cracking conditions to provide a cracked stream comprising additional amounts of ethylene and propylene. Finally, the cracked stream is passed to the product separation zone to recover additional amounts of propylene.

Abstract: A process is present for increasing the yields of 1,3 butadiene. The process includes recovering 1,3 butadiene from a cracking unit that generates a crude C4 stream. The 1,3 butadiene is separated and the remaining C4 process stream components are further reacted and dehydrogenated to generate 1,3 butadiene in a subsequent process stream. The subsequent process stream is recycled to recover the additional 1,3 butadiene.

Abstract: Processes for providing an isobutane recycle stream to be recycled to a dehydrogenation zone. In some embodiments a dividing wall column is used to separate a hydrogenation effluent. The hydrogenation effluent may include olefins, or it may be fully saturated. A hydrogenation zone may include a nickel based catalyst and may fully saturate dienes and olefins, or only hydrogenate dienes.
