Abstract:
A process for reforming a hydrocarbon stream is presented. The process involves increasing the processing temperatures in the reformers. 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. The process utilizes a common catalyst, and common downstream processes for recovering the desired aromatic compounds generated.
Abstract:
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.

Abstract:
A catalyst and a process for using the catalyst are disclosed generally for the conversion of hydrocarbons. The catalyst has an increased average bulk density and a decreased mass ratio of platinum-group metal. The process using the catalyst obtains unexpected high activity and stability for the reforming of naphtha range hydrocarbons. Mössbauer spectroscopy is used to characterize the extent of tin association with platinum and determine an effective molar tin ratio appropriate for alumina supports with densities above 0.6 g/cc.
Abstract:
A catalyst and a process for using the catalyst are disclosed generally for the conversion of hydrocarbons. By the use of at least one high temperature calcination under dry conditions, a catalyst with a beneficial combination of lowered surface area and excellent piece crush is created. X-ray diffraction pattern information is used to distinguish the resulting product.

Abstract:
An exemplary embodiment can be a process for removing one or more polynuclear aromatics from at least one reformate stream from a reforming zone. The PNAs may be removed using an adsorption zone. The adsorption zone can include first and second vessels each vessel containing an activated carbon adsorbent. Generally, the process includes passing the at least a portion of an effluent of the reforming zone through the first vessel containing a first activated carbon adsorbent wherein the first activated carbon adsorbent comprises iron.
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.
