Tri-reforming: A new biogas process for synthesis gas and hydrogen production

► High methane and carbon dioxide conversions were reached in biogas DR process. ► For TR process at O2/CH4 = 0.25 and S/C = 1.0 the highest hydrogen yields were reached. ► The Rh-Ni/Ce-Al2O3 catalyst achieved the highest hydrogen production yield. ► Similar conversions were achieved at much higher WHSV in microreactors. ► Higher TOF and PROD values were obtained operating with microreactors.
