preparation example Construction
[0029] The present invention has no limitation on the preparation method of the dehydrogenation catalyst, as long as the active metal can be loaded on the carrier; preferably, the metal precursor is dissolved in deionized water to obtain a metal precursor solution; the metal precursor solution It is introduced onto the support by means of co-impregnation or step-by-step impregnation, and the impregnation can be saturated impregnation or supersaturated impregnation. When the catalyst contains two or more active metals, the co-impregnation means that two or more metal elements can be dissolved together in deionized water, and then the impregnating solution is impregnated on the carrier, followed by drying and roasting. The step-by-step impregnation is to dissolve two or more active metal elements in deionized water respectively, and impregnate the metal impregnating solution on the carrier respectively, and the carrier obtained after each impregnation needs to be dried and roaste...
