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. Still further, the method includes contacting the dehydrated hydrogen chloride gas with additional spent chloride-containing hydrocarbon conversion catalyst to sorb chlorine onto the additional spent chloride-containing hydrocarbon conversion catalyst.

Systems and methods for separating chlorine-containing species from aqueous solutions of chlorine-containing species

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.

Integrated hydrogenation/dehydrogenation reactor in a catalytic reforming process configuration for improved aromatics production

Provided is a process for producing aromatics including the steps of preparing a Chydrocarbon stream, feeding a naphtha stream and the Chydrocarbon stream to a reforming unit, and reforming the naphtha stream and the Chydrocarbon stream to yield aromatics. The process combines a co-feed containing Chydrocarbons, 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.

Process for xylenes production

A reforming process includes an endpoint reduction zone for converting Ccomponents via selective hydrogenation and hydrodealkylation to lower boiling point aromatics, such as benzene, toluene, and xylene, or their single ring aromatic C-Cprecursors.

Enhanced aromatics production by low pressure end point reduction and selective hydrogenation and hydrodealkylation

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.

Initial hydrotreating of naphthenes with subsequent high temperature reforming

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.

Integrated hydrogenation/dehydrogenation reactor in a platforming process

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.

Co-current catalyst flow with feed for fractionated feed recombined and sent to high temperature reforming reactors

An apparatus for reforming a hydrocarbon stream is presented. 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.

High temperature platformer

A process is presented for increasing the aromatics content in a reformate process stream. The process modifies existing processes to change the operation without changing the reactors or heating units. The process includes bypasses to utilize heating capacity of upstream heating units, and passes the excess capacity of the upstream heating units to downstream process streams.

High temperature CCR process with integrated reactor bypasses

A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and passing each feedstream to separation reformers. The reformers are operated under different conditions to utilize the differences in the reaction properties of the different hydrocarbon components. The process utilizes a common catalyst, and common downstream processes for recovering the desired aromatic compounds generated.
