Life of catalyst without regeneration in the catalytic dehydrogenation of isopentane

An investigation was made into the duration of the working life without regeneration for a catalyst for the dehydrogenation of isopentane at 500°, 527°, and 550°: the higher the reaction temperature, the more rapid the fall in catalyst activity.
At 550° it is most advantageous to carry out the reaction in short working cycles (not more than one hour) at high space velocities. At 527° the dehydrogenation of isopentane can be carried out in longer cycles of about three hours, and at 500° still longer working cycles of 6–8 hours can be used.
