摘要： L'invention se rapporte à un catalyseur et à un procédé qui sont particulièrement efficaces pour déshydrogéner plusieurs hydrocarbures saturés C3 à C6. Le catalyseur, qui est fabriqué selon un procédé de préparation simplifié, est constitué par un tamis moléculaire en silicate alumineux chargé de platine qui présente la structure cristalline MFI. Lorsqu'il est utilisé pour déshydrogéner des alcanes, ce catalyseur soutenu ou non soutenu, a une longue durabilité et possède également d'excellentes caractéristiques de conversion et de sélectivité pour l'oléfine correspondante, tout en ne subissant qu'un encrassement minimal.

摘要： A catalyst and an improved process for producing olefins by catalytic naphtha cracking are described. The process provides relatively higher yields over a commercially important range of naphtha conversion, while providing about the same or lower yields of aromatics and methane over the range. In the process, a hydrocarbon naphtha feedstock including a hydrocarbon having about three to about twenty carbon atoms per molecule is passed into a reactor containing a pentasil zeolite catalyst. The catalyst includes about 0.1 to about 10 weight percent phosphorus and about 0.1 to about 10 weight percent of a promoter metal selected from the group consisting of gallium, germanium, tin and mixtures thereof. The hydrocarbon may be passed into the reactor together with a diluent selected from the group consisting of steam, nitrogen, methane, and ethane and mixtures thereof. Alternatively, the hydrocarbon may be passed into the reactor together with additional propane.

摘要： A catalyst and process are described which are particularly effective in the dehydrogenation of one or more C3 to C6 saturated hydrocarbons. The catalyst, made by a simplified preparation process, is a platinum-loaded aluminosilicate molecular sieve exhibiting the MFI structure. The supported or unsupported catalyst when used to dehydrogenate alkanes is long-lived; it also has an excellent conversion and selectivity to the corresponding olefin while exhibiting minimal coking.
