The present invention relates to a process for producing cumene and/or ethylbenzene from a mixed hydrocarbon feedstream comprising subjecting C6 cut separated from said mixed hydrocarbon feedstream to aromatization to provide an aromatization product stream and subjecting the thus obtained aromatization product stream to alkylation to produce an alkylated aromatic stream.

The present disclosure is directed to methods of producing zincoaluminosilicate structures with AEI, CHA, and GME topologies using organic structure directing agents (OSDAs), and the compositions and structures resulting from these methods.

A method for producing a highly aromatic base oil of the present invention includes a step of hydrorefining a clarified oil to obtain a highly aromatic base oil having an aromatic content of 50% by mass or more determined by a column chromatography analysis method. The step of hydrorefining a clarified oil is preferably performed under conditions of a hydrogen pressure of 5.0 to 20.0 MPa, a temperature of 280 to 400 C., a hydrogen oil ratio of 300 to 750 NL/L, and a space velocity of 0.3 to 2.0 h.sup.1. According to the present invention, a highly aromatic base oil used for rubber processing, asphalt reclamation and the like, and a novel method for producing a highly aromatic base oil can be provided.

The invention relates to the hydrocarbon upgrading to produce aromatic hydrocarbon, to equipment and materials useful in such upgrading, and to the use of such upgrading for, e.g., producing aromatic hydrocarbon natural gas. The upgrading can be carried out in the presence of a dehydrocyclization catalyst comprising at least one dehydrogenation component and at least one molecular sieve.

The present disclosure is directed to producing zeolite structures with GME topologies using organic structure directing agents (OSDAs) comprising a piperidinium cation, and the compositions and structures resulting from these methods. In some embodiments, the crystalline products have a molar ratio of a molar ratio of Si:Al that is greater than 3.5.

Methods and systems for improved catalytic reforming are disclosed. A method of catalytic reforming includes feeding a feedstream comprising C.sub.6-convertibles to one or more reactors; contacting the feedstream with a reforming catalyst; selecting values for a LHSV, a H2/HC ratio, and a conversion of C.sub.6-convertibles from a deactivation kinetic model so as to maximize a net present amount of benzene produced over a run-length of the reforming catalyst; operating the one or more reactors at the selected LHSV, the selected H2/HC ratio, and the selected conversion of C.sub.6-convertibles; and recovering an effluent from the reactor, wherein the effluent comprises at least about 40 wt % benzene.
