摘要： A simulated moving bed adsorptive separation process for preparing the separate feed streams charged to naphtha reforming unit and a steam cracking unit has been developed. The feed stream to the overall unit is passed into the adsorptive separation unit. The desorbent in the adsorptive separation is C12 hydrocarbons. The simulated moving bed adsorptive separation separates the components of the feed stream into a normal paraffin stream, which is charged to the steam cracking process, and non-normal hydrocarbons which are passed into a reforming zone. The desorbent is readily separated from the normal paraffin stream and from the non-normal paraffin stream and the simulated moving bed adsorption zone is operated at an A/Fn ratio of from about 0.90 to about 0.92.

摘要： Adsorbents and methods for the adsorptive separation of para-xylene from a mixture containing at least one other C8 aromatic hydrocarbon (e.g., a mixture of ortho-xylene, meta-xylene, para-xylene, and ethylbenzene) are described. Suitable adsorbents comprise nano-size zeolite X having an average crystallite size of less than about 500 nanometers. The adsorbents provide both improved capacity and mass transfer, which is especially advantageous for improving productivity in low temperature, low cycle time adsorptive separation operations in a simulated moving bed mode.

摘要： A novel process effective for the removal of organic sulfur compounds, organic nitrogen compounds and light olefins from liquid hydrocarbons is disclosed. The process more specifically addresses the removal of these contaminants from aromatic compounds including benzene and toluene and from naphtha. The liquid hydrocarbons are contacted with a blend of at least one metal oxide and an acidic zeolite. Preferably, the metal oxide comprises nickel oxide and molybdenum oxide and the acidic zeolite is acidic stabilized zeolite Y. This blend has a significant capacity for adsorption of impurities and can be regenerated by oxidative treatment.

摘要： For the removal of trace quantities of iodine-containing contaminants from corrosive liquid feed streams, an alternative with distinct advantages over the prior art is provided. The treatment method involves the use of a crystalline manganese phosphate which has been cation-exchanged with an iodine-reactive metal. This inorganic adsorbent may be used in unbound form, or it can bound with a substantially insoluble porous inorganic refractory metal oxide binder. A reactivation technique for this material is also presented.

摘要： A novel continuous process for the preparation of alkylated benzenes effected by solid catalysts which become deactivated under alkylation conditions uses a single catalyst zone for both reaction and catalyst flushing to prevent deactivation. The process utilizes a pulsed flow of the linear monoolefins into the catalyst zone during a reaction cycle with benzene acting as a desorbent for catalyst deactivating agents to prevent significant catalyst deactivation. The process can be generalized to encompass many types of reactions.
