Fixed bed catalytic cracking process
WebBy 1942, 14 Houdry fixed-bed catalytic units were producing high-octane aviation fuel for the armed forces. World War II ... Among others at the company who helped Houdry in the development of the catalytic cracking process was Alex Golden Oblad. The process was further developed by two MIT engineers, Warren ... WebOne of the effective catalyst for the catalytic cracking process are zeolites, such as HZSM-5, as the catalytic cracking over HZSM-5 gave high yield of gasoline fraction [2, 4, 6-1 0]. The main drawback in using HZSM-5 as a catalyst is the selectivity for gaseous product obtained from the catalytic cracking process which was also high, and it ...
