Claim 1
Independent Claim
80 words
A PROCESS FOR THE DEHYDROGENATION OF HYDROCARBONS HAVING AT LEAST FOUR CARBON ATOMS WHICH COMPRISES CONTACTING IN THE VAPOR PHASE AT A TEMPERATURE OF FROM GREATER THAN 250*C TO ABOUT 750*C. A MIXTURE OF THE SAID HYDROCARBON TO BE DEHYDROGENATED AND FROM 0.2 TO 2.5 MOLS OF OXYGEN PER MOL OF THE SAID HYDROCABON WITH A CATALYST FOR THE DEHYDROGENATION COMPRISING MAGNESIUM FERRITE TO PRODUCE A DEHYDROGENATED HYDROCARBON PRODUCT HAVING THE SAME NUBMER OF CARBON ATOMS AS THE SAID HYDROCARBON.
