Abstract: Disclosed is a method for separating a chlorine-containing species from an aqueous solution of the chlorine-containing species in a catalytic hydrocarbon conversion process that includes the step of oxidizing a spent chloride-containing hydrocarbon conversion catalyst, the spent hydrocarbon conversion catalyst including a hydrocarbon residue formed thereon. The oxidizing forms a flue gas including chlorine-containing species, water, and oxides of carbon. The method further includes contacting the flue gas with a water scrubbing stream to dissolve at least a portion of the chlorine-containing species in the water scrubbing stream to form an aqueous acid solution and contacting the aqueous acid solution with a hygroscopic liquid to generate dehydrated hydrogen chloride gas.

Abstract: A process for reforming hydrocarbons is presented. The process involves applying process controls over the reaction temperatures to preferentially convert a portion of the hydrocarbon stream to generate an intermediate stream, which will further react with reduced endothermicity. The intermediate stream is then processed at a higher temperature, where a second reforming reactor is operated under substantially isothermal conditions.

Abstract: Provided is a process for producing aromatics including the steps of preparing a C8 hydrocarbon stream, feeding a naphtha stream and the C8 hydrocarbon stream to a reforming unit, and reforming the naphtha stream and the C8 hydrocarbon stream to yield aromatics. The process combines a co-feed containing C8 hydrocarbons, an alkali/alkaline earth metal-containing reforming catalyst, and a high temperature operating regime to achieve significant improvements in a reforming process for the production of xylenes and other aromatics.

Abstract: A process for generating aromatics from a hydrocarbon feedstream is disclosed. The process includes the steps of (a) passing the hydrocarbon feedstream to a reformer, wherein the reformer is operated at a temperature greater than 540° C.; and (b) reforming the hydrocarbon feedstream to aromatics in the presence of a catalyst, wherein the catalyst comprises (i) a refractory inorganic oxide support, (ii) a platinum group metal, (iii) a Group IVA metal, (iv) a third metal selected from alkali metals and alkaline earth metals, and (v) a halogen.

Abstract: A process for the production of aromatics through the reforming of a hydrocarbon stream is presented. The process utilizes the differences in properties of components within the hydrocarbon stream to increase the energy efficiency. The differences in the reactions of different hydrocarbon components in the conversion to aromatics allows for different treatments of the different components to reduce the energy used in reforming process.

Abstract: A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and partially processing each feedstream in separate reactors. The processing includes passing the light stream to a combination hydrogenation/dehydrogenation reactor. The process reduces the energy by reducing the endothermic properties of intermediate reformed process streams.

Abstract: A process is presented for the increasing the yields of aromatics from reforming a hydrocarbon feedstream. The process includes splitting a naphtha feedstream into a light hydrocarbon stream, and a heavier stream having a relatively rich concentration of naphthenes. The heavy stream is reformed to convert the naphthenes to aromatics and the resulting product stream is further reformed with the light hydrocarbon stream to increase the aromatics yields. The catalyst is passed through the reactors in a sequential manner.

The apparatus involves changing the design of reformers and associated equipment to allow for increasing the processing temperatures in the reformers and heaters. The reformers are operated under different conditions to utilize advantages in the equilibriums, but require modifications to prevent increasing thermal cracking and to prevent increases in coking.
