This work presents the hydrogen production process from both fresh and used cooking oils. The integration of autothermal reforming and adsorption process was proposed to provide the purified hydrogen. Aspen Plus simulation based on thermodynamics calculation was performed to determine the optimal operating conditions for hydrogen production. When the Effects of oil types, steam to carbon molar ratio, reforming temperature and pressure and amount of calcium oxide on hydrogen production were examined. The results showed that the reformer should be operated at 900 K, atmospheric pressure and steam to carbon molar ratio of 5. The optimal operating conditions of adsorption process are 600 K, atmospheric pressure and amount of calcium oxide as 18 kmol/hr. For the effect of oil types, it was found that the used vegetable oil can produce the highest amount of hydrogen, followed by fresh vegetable oil, used animal fat and fresh animal fat, respectively.
