Hydrogen production from bio-oil: A thermodynamic analysis of sorption-enhanced chemical looping steam reforming

Thermodynamic analysis of hydrogen production via sorption-enhanced chemical-looping reforming

Abstract: Hydrogen production via Sorption-Enhanced Chemical-Looping reforming combines hydrocarbons reforming (in this case methane reforming), by chemical-looping auto-thermal reforming, with water-gas shift and carbonation reactions. Both H2 production rate and concentration depend on the chemical equilibrium that is established in the fuel reactor and that is influenced by several parameter...

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...

Waste lubricating oil as a source of hydrogen fuel using chemical looping steam reforming

Initial results are presented for the production of hydrogen from waste lubricating oil using a chemical looping reforming (CLR) process. The development of flexible and sustainable sources of hydrogen will be required to facilitate a ‘hydrogen economy’. The novel CLR process presented in this paper has an advantage over hydrogen production from conventional steam reforming because CLR can use ...
