Abstract:

An emerging option for the production of hydrogen from biomass is a two­step process that includes fast pyrolysis of biomass followed by gasification of pyrolysis vapors or liquids (bio­oil). Pyrolysis is used to convert biomass to a liquid that can be transported then converted to hydrogen and carbon dioxide in either centralized or distributed manner. In this work we successfully performed POX/SR of bio­oil using a fixed­bed reactor with Rh catalyst to which bio­oil was introduced as a fine mist generated by an ultrasonic nozzle. Partial oxidation tests of a 90% bio­oil, 10% methanol mixture produced syngas (CO + H2) with the yield of about 50% of the stoichiometric potential. POX/SR produced 7.2 g hydrogen from 100 g bio­oil/methanol mixture. This yield would increase to 9.3 g/100 g bio­oil with complete water­gas shift conversion.
