Abstract

This study demonstrated that aqueous fraction of pyrolysis oil can be efficiently gasified into fuel gases methane and hydrogen via supercritical water gasification (SCWG) at moderate temperatures (500–700°C) over Ni20%Ru2%/γ-Al2O3 catalyst. All experiments were performed in a bench-scale continuous down-flow tubular reactor packed with the catalyst. Carbon gasification efficiency of 0.91 mol/mol-C (converted into CH4 and CO2) was achieved in SCWG of the aqueous fraction of pyrolysis oil (containing 2.98 wt % C) at 700°C in the presence of the catalyst. A similar carbon gasification efficiency (approx. 0.89 mol/mol-C) was obtained at a lower temperature (600°C) with a diluted feedstock (0.7 wt %C). Scanning Electron Microscopy coupled with Energy Dispersive x-ray and inductively coupled plasma analysis results confirmed that this catalyst was stable during SCWG of aqueous fraction of pyrolysis oil after 6 h on-stream. © 2016 American Institute of Chemical Engineers AIChE J, 62: 2786–2793, 2016. © 2016 American Institute of Chemical Engineers
