“…The authors reported the optimal conditions for hydrogen production by sorption enhanced SRB at 773 K with S/BtOH of 12 with CaO/BtOH of 4. But the thermal efficiency was lower than that reported by Wang and Cao [64]. Thermal efficiencies of 76.6 and 81.15 % were reported by the authors and Wang and Cao respectively.…”

Summary:This review paper examines the use of steam reforming to convert bio-liquids like ethanol, glycerol, butanol, vegetable oil, bio-oils and biodiesel into hydrogen gas. The focus of the research was to investigate the research being undertaken in terms of catalyst developments for the steam reforming of the above mentioned feedstock, and to determine the perspective opportunities in this area. Hydrogen production by steam reforming of biooil, ethanol, and pure glycerol has been widely investigated; several thermodynamic and catalytic investigations are available restricting new investigations. In contrast, hydrogen production from waste streams, vegetable oil, biodiesel and butanol is very recent and has room for further developments.

The reaction enthalpy (ΔH) of reforming processes like steam and dry (CO 2 ) reforming is of great importance for scale-up and process development. Generally, the reforming processes are considered endothermic in nature. However, a detailed study of the reaction enthalpy of reforming process, taking the example of dry reforming of ethanol considered in this study, reveals the existence of exothermic reaction enthalpy at low temperatures. A study of reaction enthalpy of ethanol dry reforming within pressure (1-10 bar), temperature range (300-900°C), and CO 2 to carbon in ethanol ratio (CCER 1-5) was initiated to determine the existence of thermoneutral temperatures for the overall reaction. The variation of thermoneutral conditions and product yields at the thermoneutral temperatures was studied. The utilization potential of the products generated at thermoneutral conditions was also evaluated. The low-pressure thermoneutral operation favored higher hydrogen production, lower methane and water formation, whereas the high-pressure thermoneutral operation favored product gas of lower syngas ratio with higher CO 2 conversion (utilization) in the process. The study can be extended to steam and dry reforming of other fuels to generate valuable products at thermoneutral conditions avoiding use of air in the process and subsequent N 2 dilution of the product gas.
