    摘要： A catalyst system comprising a first solid material comprising a silicoaluminophosphate and a second solid material comprising a zeolite and a compound containing zinc and a metal selected from the group consisting of Group IIIA and Group VIB, and a method of preparing such catalyst system, are disclosed. The thus-obtained catalyst system is employed as a catalyst in the conversion of at least a portion of a hydrocarbon feedstock comprising oxygenated hydrocarbons to aromatics (BTX), and, in particular, xylenes. In an alternate embodiment, a hydrocarbon feedstock comprising oxygenated hydrocarbons are converted to aromatics by sequentially contacting the hydrocarbon feedstock with the first solid material and then the second solid material.

    摘要： A composition, a process for producing the composition, and a hydrocarbon conversion process for converting a hydrocarbon stream such as, for example, gasoline, to olefins and C6 to C8 aromatic hydrocarbons such as toluene and xylenes are disclosed. The composition comprises a silylated catalyst which comprises a zeolite, a clay or silica, and a promoter. The process for producing the composition comprises the steps: (1) combining a zeolite with a clay or silica and a promoter under a condition sufficient to bind the clay to the zeolite to produce a clay-bound zeolite; (2) heating the clay-bound zeolite to produce a modified zeolite; and (3) silylating the modified zeolite with a silylating agent. The hydrocarbon conversion process comprises contacting a hydrocarbon stream with the catalyst composition under a condition sufficient to effect the conversion of a hydrocarbon to an olefin and a C6 to C8 aromatic hydrocarbon.

    摘要： A process for isomerizing hydrocarbons is disclosed. The process includes contacting, under reaction conditions, a hydrocarbon-containing fluid containing a saturated hydrocarbon, preferably a normal paraffin containing in the range of from about 4 carbon atoms to about 10 carbon atoms per molecule, with a composition in a single-stage reaction zone. The process includes isomerizing such saturated hydrocarbon to thereby provide a product containing an isomerized hydrocarbon. The composition used in the process contains a zeolite and a metal carbide. The composition can be produced by combining a metal, preferably such metal is in a metal compound, with the zeolite to thereby provide a metal-promoted zeolite. The metal-promoted zeolite is then calcined or steamed followed by contacting the resulting zeolite with a hydrocarbon, preferably in the presence of hydrogen, to thereby provide a carburized metal-promoted zeolite.

The process for producing the composition comprises the steps: (1) combining a zeolite with a clay or silica and a promoter under a condition sufficient to bind the clay to the zeolite to produce a clay-bound zeolite; (2) heating the clay-bound zeolite to produce a modified zeolite; and (3) silylating the modified zeolite with a silylating agent.
