Abstract: AN IMPROVED METHOD FOR THE DEHYDROGENATION OF PARAFFINS AND MONOOLEFINS, TO PRODUCE OLEFIN COMPONENTS CONTAINING A GREATER RATIO OF CARBON TO HYDROGEN, IN THE PRESENCE OF A CHROMIA-ALUMINA DHYDROGENATION CATALYST IS DISCLOSED. THE ACTIVITY AND SELECTIVITY OF THE CATALYST ARE MAINTAINED BY PERIODICALLY REGNERATING THE CATALYST AT A TEMPERATURE ABOVE ABOUT 1150* OR 1200* F., PREFERABLY FROM ABOUT 1300* TO 1500* F., AND AT LEAST ABOUT 75*F., PREFERABLY AT LEAST ABOUT 100*F., ABOVE THE AVERAGE TEMPERATURE OF DEHYDROGENATION. THE HIGHER TEMPERATURES ARE ACHIEVED BY BURNING OF CARBONACEOUS DESPOSITS ON THE CATALYST. COKE-FORMERS CAN BE ADDED TO THE REGENERATION GAS, TO INCREASE THE REGENERATION TEMPERATURE.

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.

Abstract: A method for reactivation of oxide catalysts which have been deactivated by carbonaceous materials deposited thereon in the course of hydrocracking crude oils, coal tars or shale tars and for simultaneously obtaining technical grade hydrogen of 90-95 vol. % purity containing a maximum of 5 percent of carbon monoxide. Catalyst reactivation is effected by a steam-oxygen mixture having a steam-to-oxygen ratio of 7:1 to 10:1, preferably of 9:1, at a temperature of from 600* to 750*C, and under 20-30 atm pressure. Catalyst reactivation yields a gas consisting essentially of carbon dioxide and hydrogen and containing insignificant proportions of H2S, CO and CH4, the removal of CO2 and H2S from the product gas being effected by absorption with water and an alkaline agent under a pressure of 20-30 atm. The method makes it possible to dispense with the CO conversion step.
