A METHOD OF CRACKIG HIGHER BOILING HYDROCARBONS TO PRODUCE GASOLINE BY CONTACTING A HIGHER BOILING HYDROCARBON OIL AT A CRACKING TEMPERATUE BETWEEN ABOUT 850* F. AND 1100*F. FOR A SELECTED TIME WITH A SOLID STABLE CATALYST CONSISTING ESSENTIALLY OF ABOUT 35 TO 65% BY WEIGHT OF BORON OXIDE AND THE REMINDER MAGNESIA TO EFFECT THE DESIRED EXTENT OF CRACKING TO PRODUCE A GASOLINE WHICH IS MORE OLEFINIC AND LESS AROMATIC THAN GASOLINE PRODUCED BY CONVENTIONAL CATALYTIC CRACKING.
