Abstract: AN INSTALLATION FOR MANUFACTURING GAS UNDER PRESSURE IN WHICH LIQUID OR GASEOUS PETROLEUM HYDROCARBONS ARE CRACKED UNDER PRESSURE ON A WEAK CATALYST IN THE PRESENCE OF STEAM IN A FIRST OF SERIES OF REACTORS, WHILE SIMULTANEOUSLY, IN ANOTHER SERIES OF REACTORS THE USED WEAK CATALYST IS REGENERATED BY MEANS OF A CERTAIN QUANTITY OF STEAM AND AIR AT THE SAME PRESSURE AS THE CRACKING PROCESS. THIS CRACKING AND REGENERATION BEING CARRIED OUT WHILE EXTERNAL HEAT IS CONTINUOUSLY APPLIES. THE GASES RESULTING FROM THE CRACKING AND REGENERATION PROCESS BEING MIXED TOGETHER TO FORM A BASIC GAS WHICH IS PURIFIED AT THE SAME PRESSURE AS THAT USED DURING THE CRACKING PROCESS AND THEN SUBJECTED TO AN AUTO-HYDROGENATION PROCESS IN THE PRESENCE OF A SECOND CATALYST INCLUDING A METAL OF THE PLATINUM FAMILY.
