Abstract
The present invention relates to a method for preparing, activating and regenerating a metal supported catalyst, comprising: treating a M-M-Mmetal supported catalyst at 10-700° C. by using an ammonia or nitrogen-containing organic matter, wherein the Mmetal 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 Mmetal is dispersed on the support in a state of single atomic site. According to the M-M-Mmetal 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.
