摘要: The present invention relates to a dehydrogenation process starting from reagents selected from single butenes, or mixtures thereof, or mixtures of butenes with butanes, to give 1-3 butadiene using catalytic composition of microspheroidal alumina and an active component containing a mixture comprising Gallium and/or Gallium oxides, Tin and/or Tin oxides, a quantity ranging from 1 ppm to 500 ppm with respect to the total weight of the catalytic composition of platinum and/or platinum oxides, and oxides of alkaline and/or alkaline earth metals.
