Sorption and Reaction of Biomass Derived HC Blends and Their Constituents on a Commercial Pt–Pd/Al2O3 Oxidation Catalyst

Abstract Within the Research Cluster of Excellence “The Fuel Science Center” at RWTH Aachen University, production and application new fuels from bio-based carbon feedstocks CO 2 with hydrogen renewable electricity generation is being investigated. In this study, storage oxidation ethanol, 1-butanol, 2-butanone, cyclopentanone, cyclopentane as well two blends thereof on a series Pt–Pd/Al O 3 catalyst were Hydrocarbon (HC) temperature-programmed surface reaction (TPSR) experiments carried out to analyze their adsorption desorption behavior. addition, individual HCs both investigated using Diffuse Reflectance Infrared Fourier Transform Spectroscopy (TP-DRIFTS). general, all oxygenated are adsorbed more strongly than due higher polarity. Interestingly, it could be observed that different [blend 1: ethanol (50 mol %), 2-butanone (21 cyclopentanone (14 %) (15 %); blend 2: 1-butanol (45 (29 (27 %)] exhibit behavior compared single hydrocarbons. It was shown presence in inhibits ethanol. As result, light-off temperature increased by least 100 K. A difference also found cyclopentane. While no significant detected pure compound experiment, mixtures showed larger amount stored. The species hydrocarbons corresponding products has been demonstrated gives an insight into mechanism blends. Graphic
