A process of bio-methanol from biogas was studied by modifying kinetic model of reaction’s Richardson and Paripatyadar comparing with laboratory data. Bio-methanol process consists of 2 steps: reforming reaction (at atmospheric pressure, temperature 500 750 oC) and methanol synthesis (at constant pressure 40 bar, temperature 140 280 oC). The reaction model of each step was individual simulated. Next both steps were integrated, then they were simulated using ASPEN PLUS software. This work investigated the optimum operating condition and predicted result of both reactions. The developing model was obtained, then it was applied for ten thousand liters per day of methanol. The simulation result received from reforming reaction showed increasing temperature effect to rising in CH4 and CO2 conversion and relating with laboratory result. The optimum condition of methanol synthesis is temperature 200 oC under constant pressure 40 bar.
