Abstract: A PROCESS FOR THE LONG-TERM OPERATION OF A CONTINUOUSLY OPERATED HETEROGENEOUS CATALYZED PARTIAL DEHYDROGENATION OF A HYDROCARBON TO BE DEHYDROGENATED, IN WHICH A STREAM OF REACTION GAS MIXTURE CONTAINING THE HYDROCARBON TO BE DEHYDROGENATED IN A MOLAR STARTING AMOUNT HC IS PASSED THROUGH A TOTAL CATALYST BED CONTAINING THE TOTAL AMOUNT M OF DEHYDROGENATION CATALYST AND DEACTIVATION OF THE TOTAL CATALYST BED IS COUNTERACTED BY, AS THE PERIOD OF OPERATION INCREASES, THE CONVERSION CONTRIBUTION OF THE FIRST THIRD IN THE FLOW DIRECTION OF THE TOTAL AMOUNT M OF DEHYDROGENATION CATALYST DECREASING, THE CONVERSION CONTRIBUTION OF THE LAST THIRD IN THE FLOW DIRECTION OF THE TOTAL AMOUNT M OF DEHYDROGENATION CATALYST INCREASING AND THE CONVERSION CONTRIBUTION OF THE SECOND THIRD IN THE FLOW DIRECTION OF THE TOTAL AMOUNT M OF DEHYDROGENATION CATALYST GOING THROUGH A MAXIMUM.
