Abstract

Thermodynamic properties of ethanol-glycerol steam and dry reforming have been studied with the method of Gibbs free energy minimization for hydrogen production. Equilibrium compositions were determined as a function of H2O/ethanol-glycerol molar ratios (WEG)(1:6-6:1) and CO2/ethanol-glycerol molar ratios (CEG)(1:6-6:1) where ethanol-glycerol is 1:1; reforming temperatures (573-1273 K) at different pressures (1-20 bar). Optimum conditions for hydrogen production are different for both steam and dry glycerol reforming. The optimum hydrogen formation for glycerol dry reforming are temperatures 1073-1273 K and CEG of 6:1 at 1 bar pressure, whereas for glycerol steam reforming, the optimum temperature is above 1073 K and WEG ratio 6:1 and 1 bar. Higher pressure and higher WEG/CEG ratio do not encourage hydrogen formation. Under identified optimum conditions, carbon formation can be thermodynamically inhibited.

Thermodynamic Analysis of Hydrogen Production from Methanol-Ethanol-Glycerol Mixture Through Dry Reforming

Zaki Yamani Zakaria, Mazura Jusoh, Ramli Mat, Mohd Johari Kamarudin, Jega Jewaratnam

Abstract. Thermodynamic properties of methanol-ethanol-glycerol dry reforming have been studied with the method of Gibbs free energy minimization for hydrogen production from methanolethanol-glycerol mixture. Equilibrium compositions were determined as a function of CO2/methanol-ethanol-glycerol molar ratios (CMEG) (1:6-6:1) where methanol-ethanol-glycerol is 1:1:1; reforming temperatures (573-1273 K) at atmospheric pressure (unless stated otherwise).
Optimum conditions for hydrogen production are CMEG 1:6, temperature 1273, 1 bar pressure. This point is also optimum for the production of synthesis gas. Higher pressure and higher CMEG ratio does not encourage hydrogen formation. Under identified optimum conditions, carbon formation can be thermodynamically inhibited. Nevertheless, the carbon yield can be reduced through reforming at higher temperatures.
