Catalytic reforming of model biomass-derived producer gas

This work includes a complete study of the reaction of reforming a simulated producer gas stream comparing a Ni-based catalyst with another one promoted with potassium to enhance the resistance to coke formation. Although coke deposition is unavoidable in the presence of tars in the stream, the anal...

Although coke deposition is unavoidable in the presence of tars in the stream, the analysis of different reaction parameters revealed that operating at 750 °C, weight hourly space velocity (WHSV) of 60 L−1 g−1 h−1 and 10–20 vol% of steam is possible to minimize the accumulation of carbon deposits. Moreover, it was demonstrated that the addition of potassium helps to mitigate carbon formation, but a high concentration of steam leads to nickel sintering and/or partial oxidation of metallic nickel. On this basis, it was successfully evidenced that the Ni-K catalyst is an excellent candidate for obtaining clean syngas from producer gas reforming.Financial support for this work has been obtained from the Spanish Ministerio de Economía y Competitividad – MINECO (RTI2018-096294-B-C33 and ENE2015-66975-C3-2-R projects) co-financed by FEDER funds from the European Union and the Universidad de Sevilla-Junta de Andalucía Program under contract US-1263288.
