Obtaining hydrogen from renewable energy is a novel method. Instead of single support catalysts, mixed zeolite supports were used in this study to obtain hydrogen by steam catalytic reforming of wood vinegar. This technique improves the activity and extends the life of catalysts. The results show that, compared with a single support catalyst, mixed supports are beneficial for improving H₂ concentration and anticarbon ability. H₂ content and yield increased from 54.77% to 60.32% and 18.91 mg/g sample to 22.47 mg/g sample, respectively, when γ-Al₂O₃ mixed MCM-41 supports were used instead of single γ-Al₂O₃. Moreover, the amount of carbon deposition significantly decreased from 9.79% to 5.85%. The admixture of support γ-Al₂O₃ with MCM-41 optimized the diversity of acidic intensity, structure, pore characteristics, and heat and mass transfer ability of mixed catalysts, and improved the reactivity and resistance to carbon deposition of catalysts.
