Abstract
A novel honeycomb-shaped PtSnNa/γ-Al2O3/cordierite monolithic catalyst (Pt 0.5%, Sn 0.9%, Na 1.0%, relative to Al2O3 weight) was developed and its catalytic performances in propane dehydrogenation were tested and compared with the classical granule catalyst with same Pt, Sn and Na contents under the conditions of 0.1MPa, 590°C,C3H8/H2 at 3/1 (molar ratio) and gas hourly space velocity (GHSV) at 155h−1. Interestingly, despite the generated coke amount and exposed Pt fraction, the honey comb-shaped structure of monolithic catalyst exerted important influences on its catalytic activities and led to the advanced catalytic performances over the granule catalyst.
