Blends of bio-oil/biogas model compounds for high-purity H2 production by sorption enhanced steam reforming (SESR): Experimental study and energy analysis

Hydrogen production by sorption-enhanced steam reforming of glycerol.

Catalytic steam reforming of glycerol for H(2) production has been evaluated experimentally in a continuous flow fixed-bed reactor. The experiments were carried out under atmospheric pressure within a temperature range of 400-700 degrees C. A commercial Ni-based catalyst and a dolomite sorbent were used for the steam reforming reactions and in situ CO(2) removal. The product gases were measured...

Multifunctional Pd/Ni-Co Catalyst for Hydrogen Production by Chemical Looping Coupled Sorption Enhanced Steam Reforming of Acetic Acid

High yield of H2 of high purity from acetic acid, a model compound of bio-oil from the biomass fast pyrolysis, was produced by sorption enhanced steam reforming (SESR). An oxygen carrier was introduced into a chemical loop (CL) coupled to the cyclical SESR process to supply heat in situ for the endothermic sorbent regeneration, in order to increase the energy efficiency of the process. A new mu...

Sustainable Hydrogen Production by Catalytic Bio-Ethanol Steam Reforming

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...

Improved H2 Production by Ethanol Steam Reforming over Sc2O3-Doped Co-ZnO Catalysts

H2 production by catalytically ethanol steam reforming (ESR) is an effective and prospective method for the application of fuel cells. However, the catalysts’ desirable activity and stability remains an unprecedented challenge. Herein, a type of Sc2O3-doped Co-ZnO catalyst was developed by a co-precipitation method. The so-constructed Co2Zn1Sc0.3 catalyst exhibited a superb catalytic performanc...
