Abstract
Thermodynamic equilibrium analysis of glycerol steam
reforming to ethylene has been investigated based on the
total Gibbs free energy minimization method. Equilibrium
product compositions for glycerol steam reforming were
determined for temperatures ranging from 573-1273 K and
GWR (glycerol/water ratio) 1:12 to 2:1 at 1 bar pressure.
The objectives of this study are to identify the
thermodynamic range of the process operation and study
the variation of product distribution. It was found that
the formation of ethylene was difficult to accomplish and
the amount of ethylene produced is very small. The
formation of coke, which will poison the catalyst, could
be suppressed at higher operating temperature. The
thermoneutral temperature of the process was found to
increase with GWR. Other means to encourage the formation
of more ethylene is required
