Catalyst for paraffin dehydrogenation

A method for dehydrogenation of an alkane, the method comprising:

• loading a reactor with an alkane dehydrogenation catalyst produced by:
• mixing a plurality of aluminum hydroxides, a water insoluble chromium (III) oxide source, and an alkali metal oxide source with an aqueous metal free acid solution to form a moldable mixture, the plurality of aluminum hydroxides containing from about 60 weight percent (wt. %) to about 99 wt. % of crystalline aluminum trihydroxide and from about 1 wt. % to about 40 wt. % of crystalline aluminum oxide-hydroxide or gelatinous aluminum hydroxide or combinations thereof;
• extruding the moldable mixture to form extrudates;
• and
• drying and calcining the extrudates to produce the alkane dehydrogenation catalyst;
• and
• supplying a feed containing alkanes through the reactor at a temperature sufficient to dehydrogenate the alkanes.
