A process for reducing the benzene content of a light reformate refinery stream comprises the following steps: a) reducing the benzene content by exposing the light reformate to hydrogenation conditions in a benzene-saturation reactor bed, b) increasing the octane number of the hydrogenated light reformate produced in step a) by exposing it to isomerization conditions, c) further reducing the benzene content by exposing the light reformate refinery stream to further hydrogenation conditions, wherein the isomerization of step b) occurs after step a), the hydrogenation of step c) does not precede the isomerization step b), and steps a), b) and c) are all carried out within the same reactor.

A catalyst is provided for hydrodeoxygenation and hydroisomerization of paraffins having higher activity. The catalyst contains a molecular sieve, such as SAPO-11, a metal component such as platinum and/or palladium or nickel tungsten sulfide or nickel molybdenum sulfide and a binder such as gamma alumina. The catalyst exhibits a high proportion of weak acid sites and a relatively equal distribution of the metal component on the molecular sieve and the binder.

Described herein are novel and inventive dewaxing processes that employ dewaxing catalysts which are co-extrusions of two different zeolites, particularly two different 10MR zeolites or a co-extrusion of a 10MR zeolite and a 12MR zeolite in combination with a hydrogenation component. The hydrogenation component can be a mixture of non-noble metal components or a mixture of noble metal components. This novel and inventive process demonstrated a significant activity boost (as measured by increased cloud point reduction) and/or selectivity boost (as measured by reduced diesel loss) compared to either single zeolite component.

In accordance with one or more embodiments of the present disclosure, a method for producing aromatic compounds from pyrolysis gasoline comprising C.sub.5-C.sub.6 non-aromatic hydrocarbons includes aromatizing the pyrolysis gasoline in an aromatization unit, thereby converting the C.sub.5-C.sub.6 non-aromatic hydrocarbons to a first stream comprising benzene-toluene-xylenes (BTX); hydrotreating the first stream comprising BTX in a selective hydrotreatment unit, thereby producing a de-olefinated stream comprising BTX hydrodealkylating and transalkylating the de-olefinated stream comprising BTX in a hydrodealkylation-transalkylation unit, thereby producing a second stream comprising BTX, the second stream comprising BTX having a greater amount of benzene and xylenes than the first stream comprising BTX; and processing the second stream comprising BTX in an aromatics recovery complex, thereby producing the aromatic compounds from the pyrolysis gasoline, the aromatic compounds comprising benzene, toluene, and xylenes.

The present disclosure is directed to microporous crystalline aluminosilicate structures with GME topologies having pores containing organic structure directing agents (OSDAs) comprising at least one piperidinium cation, the compositions useful for making these structures, and methods of using these structures. In some embodiments, the crystalline zeolite structures have a molar ratio of Si:Al that is greater than 3.5.

Methods are provided for using a molecular sieve catalyst for dewaxing formed using a synthesis mixture comprising a morphology modifier. The catalyst may be used, for example, for production of a lubricant base stock. For example, ZSM-48 crystals formed using the morphology modifier (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic dewaxing of lubricant base stocks.
