Abstract: According to one or more embodiments, olefins may be produced by contacting a hydrocarbon feed stream with a particulate solid in a reaction vessel. The reaction vessel may be connected to a riser. The riser may extend through a riser port of an outer shell of a particulate solid separation section such that the riser may comprise an interior riser segment and an exterior riser segment. The particulate solid separation section may include a gas outlet port, a riser port, and a particulate solid outlet port. The particulate solid separation section may house a gas/solids separation device and a solid particulate collection area. The riser port may be positioned on a sidewall of the outer shell such that it is not located on a central vertical axis of the particulate solid separation section. The particulate solid may be separated from an olefin-containing product stream in the gas/solids separation device.

Abstract: A process and a device for continuous flow side-chain alkylation which relate to the technical field of organic synthesis. In this process and the device for continuous flow side-chain alkylation, an ibuprofen raw material is prepared with alkylbenzene as a raw material. This raw material alkylbenzene is easily available and has a low cost, and is suitable for scale-up production. Moreover, an entire preparation process adopts continuous chemical synthesis, and a reaction time of each stage can be precisely controlled, which is beneficial to control a total reaction time and reduce an amount of impurities produced. In this way, a purity and a yield of the ibuprofen raw material are improved. In summary, a continuous synthesis method for side-chain alkylation of alkylbenzene provided by the present disclosure shows a low cost and a high yield.

Abstract: A method for processing a chemical stream includes contacting a feed stream with a catalyst in a reactor portion of a reactor system that includes a reactor portion and a catalyst processing portion. The catalyst includes platinum, gallium, or both and contacting the feed stream with the catalyst causes a reaction which forms an effluent stream. The method includes separating the effluent stream from the catalyst, passing the catalyst to the catalyst processing portion, and processing the catalyst in the catalyst processing portion. Processing the catalyst includes passing the catalyst to a combustor, combusting a supplemental fuel in the combustor to heat the catalyst, treating the heated catalyst with an oxygen-containing gas to produce a reactivated catalyst, and passing the reactivated catalyst from the catalyst processing portion to the reactor portion. The supplemental fuel may include a molar ratio of hydrogen to other combustible fuels of at least 1:1.
