Abstract: The present invention relates to a method for preparing, activating and regenerating a metal supported catalyst, comprising: treating a Ma-Mb-Mc metal supported catalyst at 10-700° C. by using an ammonia or nitrogen-containing organic matter, wherein the Ma metal is an active metal selected from one or more of a noble metal atom or a transition metal, the support is a common industrial porous catalyst, and the Ma metal is dispersed on the support in a state of single atomic site. According to the Md-Mb-Mc metal supported noble metal/zinc catalyst treated by the method of the present invention, the direct dehydrogenation conversion rate and selectivity of catalyzing light alkanes are remarkably improved; the method for preparing the catalyst is simple in process, the catalytic activity after regeneration is still kept, and the catalyst can be industrially produced on a large scale.

Abstract: Systems, reactors, and processes for regenerating ionic liquid using catalyst. A plurality of tubular reactors are provided having a first end and a second end and catalyst particles disposed in the tubular reactor between the first end and the second end. A line supplies separated ionic liquid catalyst to the first end of the tubular reactor. Hydrogen is also supplied. Regenerated ionic liquid catalyst is recovered from the second end of the tubular reactor. The inner surface of the tubular reactor is preferably non-corrosive or non-reactive. A fluoropolymer lining may be used. The tubular reactors are modular, and may be changed out with the catalyst inside when the catalyst are to be replaced.

Abstract: We provide a process for regenerating a spent acidic ionic liquid, comprising contacting the spent acidic ionic liquid with hydrogen and without an addition of a hydrogenation catalyst; wherein a conjunct polymer content is decreased in the spent acidic ionic liquid to produce regenerated acidic ionic liquid. We also provide a process for making an alkylate gasoline blending component, comprising: a) alkylating a mixture of isoparaffins and olefins using an acidic ionic liquid and an alkyl halide or a hydrogen halide, wherein a conjunct polymer accumulates in a spent acidic ionic liquid; and b) feeding the spent acidic ionic liquid and a hydrogen, and without an addition of a hydrogenation catalyst, to a regeneration reactor operated under selected hydrogenation conditions to produce a regenerated acidic ionic liquid that is used for the alkylating, wherein the conjunct polymer in the regenerated acidic ionic liquid is decreased by at least 50 wt %.

Abstract: A catalyst for the carbonylation of dimethyl ether to methyl acetate. The catalyst comprises a zeolite, such as a mordenite zeolite, at least one Group IB metal, such as copper, and/or at least one Group VIII metal, such as iron, and at least one Group IIB metal, such as zinc. Such a catalyst with combined metals provides enhanced catalytic activity, improved stability, and improved selectivity to methyl acetate, and does not require a halogen promoter, as compared to a metal-free or copper only zeolite.
