Abstract: Methods and systems for the conversion of hydrocarbon feedstocks, in particular, naphtha feedstocks, into a hydrocarbon product stream containing a high yield of high-octane gasoline and chemicals products. In particular, the conversion takes place over a series of functionally distinctive catalyst beds, at least one of which includes a modified zeolitic catalyst comprising a zeolite, a transition metal, and optionally a binder. Systems provided include a hydrocarbon feed stream, which may be full-range naphtha, a hydrocarbon product stream, and a plurality of functionally distinctive catalyst beds arranged in series, wherein at least one of the catalyst beds comprises a modified zeolitic catalyst. A hydrocarbon feed stream may be conveyed through the plurality of functionally distinctive catalyst beds, producing an intermediate hydrocarbon stream between each, under conditions effective to convert the hydrocarbon feed stream to a hydrocarbon product stream comprising high-octane gasoline, xylenes, benzene, and/or toluene.

Abstract: Methods and systems producing gasoline boiling range hydrocarbons from light paraffins are disclosed. Such methods may include exposing a paraffin-containing stream to a catalyst in a side riser of a fluid catalytic cracking reactor under effective conditions for dehydrogenating at least a portion of paraffins in the stream into olefins and thereby producing an olefin-containing stream, wherein the paraffin-containing stream comprises greater than 50 wt % isobutane; and alkylating olefins in the olefin-containing stream to produce a product stream comprising an alkylate fraction comprising hydrocarbons boiling between 100° F. and 400° F.

Abstract: A systems and method for manufacturing a base stock from an ethanol stream are described herein. An example method includes dehydrating an ethanol stream to form an impure ethylene mixture, recovering an ethylene stream from the impure ethylene mixture, and oligomerizing the ethylene stream to form a raw oligomer stream. A heavy olefinic stream is distilled from the raw oligomer stream. The heavy olefinic stream is hydro-processed to form a hydro-processed stream, and the hydro-processed stream is distilled to form the base stock.

Abstract: Systems and methods are provided for using size-reversing materials in vessels where direct heating is used to at least partially provide heat for reforming reactions under cyclic reforming conditions. An example of a size-reversing material is the combination of NiO and Al2O3. It has been discovered that size-reversing materials can undergo a phase transition that can assist with re-dispersion of metal at elevated temperatures. This can assist with maintaining catalytic activity for reforming over longer time periods in the presence of cyclic reforming conditions.

An example method includes cracking the hydrocarbon stream to form a raw hydrocarbon stream, separating an ethylene stream from the raw hydrocarbon stream and oligomerizing the ethylene stream to form a raw oligomer stream. A light olefinic stream is distilled from the raw oligomer stream and linear alpha olefins are recovered from the light olefinic stream. A heavy olefinic stream is distilled from the raw oligomer stream. The heavy olefinic stream is hydro-processed to form a hydro-processed stream. The hydro-processed stream is distilled to form the base stock.

Abstract: Catalyst systems are provided for reforming of hydrocarbons, along with methods for using such catalyst systems. The catalyst systems can be deposited or otherwise coated on a surface or structure, such as a monolith, to achieve improved activity and/or structural stability. The metal oxide support layer can correspond to a thermally stable metal oxide support layer, such as a metal oxide support layer that is thermally phase stable at temperatures of 800° C. to 1600° C. The catalyst systems can be beneficial for use in cyclical reaction environments, such as reverse flow reactors or other types of reactors that are operated using flows in opposing directions and different times within a reaction cycle.
