Steam Reforming of Bio-Compounds with Auto-Reduced Nickel Catalyst

Steam Reforming of Bio-Compounds with Auto-Reduced Nickel Catalyst

As an extension of chemical looping combustion, chemical looping steam reforming (CLSR) has been developed for H2 production. During CLSR, a steam reforming (SR) process occurs following the reduction of catalysts by the reforming feedstock itself (termed “auto-reduction”), as opposed to a separate, dedicated reducing agent like H2. This paper studied SR performances of four common bio-compound...

Stable Hydrogen Production from Ethanol through Steam Reforming Reaction over Nickel-Containing Smectite-Derived Catalyst

Hydrogen production through steam reforming of ethanol was investigated with conventional supported nickel catalysts and a Ni-containing smectite-derived catalyst. The former is initially active, but significant catalyst deactivation occurs during the reaction due to carbon deposition. Side reactions of the decomposition of CO and CH4 are the main reason for the catalyst deactivation, and these...

ZnO Nanowire-supported Ag Catalyst for Methanol Steam Reforming

Alternative energy sources, such as various fuel cell technologies, have attracted intense attention due to their high efficiency and low emissions of pollutants. Methanol, with its high hydrogen/carbon ratio, low sulfur content and the absence of carbon–carbon bonds, has been identified as a highly suitable source for onboard production of hydrogen [1]. Among several reactions for converting m...

Optimization of the preparation procedure of Ni/Al2O3 catalyst for steam reforming of n-butane

Performance of Ni/Al2O3 catalysts (10 wt.% Ni) in steam reforming of n-butane was investigated in terms of n-butane conversion, selectivity to hydrogen and hydrogen yield. The process was carried out in a fixed-bed tubular reactor at 650 °C and atmospheric pressure. The volumetric flow rates of n-butane and steam were 0.1 mL/min and 0.6 mL/min, respectively. The catalysts were prepared by preci...
