摘要: Abstract Autothermal reforming (ATR) of isobutanol, a bio-based fuel, was investigated for hydrogen production on Ru- promoted Ni xerogel catalysts and under optimized operating conditions to attain lower carbon formation the catalysts. All were prepared by sol–gel technique. Catalysts characterized X-ray diffraction (XRD), pore size, BET surface area, temperature-programmed reduction (TPR), desorption H 2 (TPD ), scanning electron microscopy (SEM), transmission (TEM) oxidation (TPO) studies investigate physicochemical changes occurring due reaction. Catalytic autothermal reactions carried out in fixed-bed reactor at atmospheric pressure. The varied temperature range from 600 750 °C, space velocity 130,000–650,000 h −1 , O/C molar ratio feed between 0 4.0, 0–1. 0.3 wt% Ru/10 wt% Ni/Ce(3 wt%) O /ZrO /Al 3 catalyst showed high catalytic activity, low deposition, good resistance sintering prolonged stability. Ru promotion not only improved appreciably, but also reduced coke studied.
