Methanol, a liquid fuel can be prepared from water gas and additional \( H _{2} \) at high temperature and pressure in the presence of suitable catalyst.
\( 2 H _{2}( g )+ CO ( g ) \rightleftharpoons CH _{3} OH ( g ), \Delta H =-92.2 KJ \)
Assuming at equilibrium:
(4)
\( v d \phi G>0 \quad \theta_{c}>k_{e} \)
