SORPTION-ENHANCED STEAM REFORMING OF ETHANOL FOR HYDROGEN PRODUCTION

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...

Steam Reforming of Ethanol: Production of Renewable Hydrogen

Abnormal growth of population and development enormously increases energy demand. In present scenario utilization of fossils fuels to meet this demand is not enough and also leads to pollution, global warming, climate change as well as natural disaster. Therefore, hydrogen as energy carrier is a major option on these prospects as it is non-polluting and renewable. The renewable hydrogen energy ...

Sustainable Hydrogen Production by Catalytic Bio-Ethanol Steam Reforming

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...

Parametric Study of Hydrogen Production from Ethanol Steam Reforming in a Membrane Microreactor

Microreactors are miniaturized chemical reaction systems, which contain reaction channels with characteristic dimensions in the range of 10-500 μm. One possible application for microreactors is the conversion of ethanol to hydrogen used in fuel cells to generate electricity. In this paper a rigorous isothermal, steady-state two-dimensional model was developed to simulate the behavior of a membr...
