Özet
Indirect partial oxidation, or auto thermal reforming, tests of a bimetallic Pt-Ni catalyst supported on δ-alumina were performed for different propane-n-butane mixtures (LPG) used as feeds. The presence of n-butane in the feed enhanced hydrogen production activity and selectivity. Higher steam content in the reactant stream increased both the activity and the H2/CO selectivity of the process. Low residence times created a positive impact on catalyst activity not only for hydrogen production but also for CO production due to the increased amount of fresh hydrocarbon in the feed stream. A comparison of catalyst performance for LPG feeds with different compositions indicated that the Pt-Ni catalyst has slightly better activity and selectivity at higher n-butane contents at the expense of becoming more sensitive to coke deposition. Considering the well established distribution network of LPG and the superior performance of the bimetallic Pt-Ni catalyst in the IPOX of LPG, Pt-Ni system seems a very promising catalyst alternative to be used in commercial fuel processors. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
