45. Activity of Yttrium Strontium Titanate-Based Catalyst over Steam Reforming of Dodecane

Hydrocarbon reforming to produce hydrogen (or syngas) on site or on board a transportation vehicle for fuel cell operation can solve the complicated problem of hydrogen storage and transportation. Using perovskite catalysts can be advantageous due to their high oxygen ion storage and lower cost. In this paper, the use of yttrium strontium titanate (YST)-based catalyst in autothermal reforming of dodecane is studied. The catalyst was prepared by the sol-gel technique and characterized by XRD. The B site was doped by noble metals such as Co, Ru, and Ni and their effect was studied. The operating temperature and pressure are 800 °C and 1 atm, respectively. Steam/carbon ratio was fixed at 3. Each test was conducted for at least 16 h. Hydrogen concentration varied between 65 and 72 % (free of water and nitrogen) with conversion rate as high as 80 to 90 %. The effect of doping at the B site on the catalyst activity is discussed.
