    摘要： The present invention provides a process for natural gas in the form, e.g., of stranded gas or associated gas to transportable liquids. More particularly, the present invention provides a process in which the gas is non-oxidatively converted to aromatic liquid, preferably in proximity to the welihead, which may be onshore or offshore. In one aspect, the present invention provides integration of separation of wellhead fluids into associated gas and crude with blending of the aromatic liquid derived from the gas with the crude. Alternatively, or in combination, in another aspect, the present invention provides integration of conversion of byproduct hydrogen to power with non-oxidative conversion of gas to aromatic liquid.

    摘要： The invention relates to a composite formed of a zeolite (such as ZSM-5 zeolite, β-zeolite and silicalite) deposited on a rigid support, wherein the rigid support comprises silicon carbide (SiC) with a specific surface area BET of at least 5 m2/g. Preferably, the support is a β-SiC foam with a specific area of between 10 and 500 m2/g. This composite may be used as a catalyst and/or a catalyst support for chemical reactions in a gas or liquid medium. For example materials of the present invention are useful for example, in connection with cracking, acylation, alkylation and/or isomerization of hydrocarbons.

    摘要： A catalyst comprising vanadium phosphorus oxide combined with a thermally conductive material is particularly useful for the selective hydrocarbon oxidations (e.g., butane to maleic anhydride) and can be prepared by forming a suspension comprising a vanadium (IV) phosphate compound in a liquid medium (via hydrochloric acid digestion of V2O5 and H3PO4 in an aqueous solvent or via heating vanadium pentoxide with at least one substantially anhydrous unsubstituted alcohol having 1-10 carbon atoms, 1-3 hydroxyl groups free from olefinic double bonds to form a feed of vanadium pentoxide reduced to a valence between 4 and 4.6, and then contacting the feed with a solution of orthophosphoric acid and at least one unsubstituted alcohol), adding a thermally conductive material to the suspension under agitation at moderated temperature between 40° C. and 120° C., followed by drying, optionally but preferably washing and calcining (either in situ or ex situ) the material thus formed.
