TESTING FUEL ECONOMY of n e w automobiles is p a r t of Detroit's continuing research to get m o r e power out of gasoline. Burette at right measures fuel c o n s u m p t i o n . Cyanamid is helping refiners meet t h e t r e n d toward p r e m i u m gasoline with a n e w catalyst — AEROCAT T R I P L E A* High Alumina Catalyst. I t is the first catalyst with high alumina cont e n t ( 2 5 % ) to p r o v e successful in full-scale commercial use. Offering higher activity and i m p r o v e d selectivity, AEROCAT T R I P L E A Catalyst boosts t h e efficiency of cracking units. It makes possible greater output of gasoline per ton of catalyst used or better cracking performance at t h e same rate of catalyst usage. (Industrial Chemicals Division)
