Olefins formation by oxidative dehydrogenation of propane over monoliths at short contact times
2000
A specially designed tubular microreactor allowing to rapidly quench reaction products was used to test performance of Pt supported onto corundum micromonoliths in the reaction of propane oxidative dehydrogenation at short contact times. Promoters known as dehydrogenation catalysts (tin, zinc aluminate spinel, transition metal pyrophosphates) were used and reaction mixture composition was tuned to increase propylene yield. FTIRS data on propane interaction with a model Pt/SiO 2 system helped to analyze the possible routes and limits of propylene yield improvement.
