This work describes the unidimensional study of steam reforming of methanol at short pseudo-contact time. Steam reforming process (SRP) is important to hydrogen production as energetic vector. A compressible mathematical model 1-D is developed. Peppley kinetic mechanism (1999) is adopted. The numerical predictions show up the same trend as the experimental ones. A sensitivity analysis of the significant variables of the process is carried out (pressure, CH3OH/H2O ratio and temperature).
 Keywords: Methanol steam reforming; Hydrogen production; 1-D reactor model.
