    摘要： A process for treating a dehydrogenation catalyst includes heating the dehydrogenation catalyst to a first temperature in the presence of a gas including oxygen for a first time period; after heating the dehydrogenation catalyst to the first temperature in the presence of the gas including oxygen, heating the dehydrogenation catalyst to a second temperature in the presence of an inert gas for a second time period; and repeating heating the dehydrogenation catalyst to the first temperature in the presence of the gas including oxygen and thereafter heating the dehydrogenation catalyst to the second temperature in the presence of the inert gas for 1 to 50 hours, or 2 to 20 hours. An example of the catalyst comprises gallium, cerium, potassium, platinum and aluminium.
