Microreactors with Pt/zeolite catalytic films for the selective oxidation of CO in simulated reformer streams
The selective oxidation (SELOX) of CO in the presence of H 2, CO 2 and H 2O has been carried out on stainless steel microreactors with 500 μm diameter microchannels. To this end, catalytic films consisting of Pt supported on zeolite Y (Pt-FAU) or ETS-10 (Pt-ETS10), were prepared by seeded hydrotherm...

Summary: | The selective oxidation (SELOX) of CO in the presence of H
2, CO
2 and H
2O has been carried out on stainless steel microreactors with 500
μm diameter microchannels. To this end, catalytic films consisting of Pt supported on zeolite Y (Pt-FAU) or ETS-10 (Pt-ETS10), were prepared by seeded hydrothermal synthesis on the surface of the reactor microchannels to give a uniform, mechanically stable catalytic coating on the channel surface. Activity tests were performed with feeds consisting of CO and H
2, plus CO
2 and/or H
2O. The best performance was obtained on microreactors coated with Pt-FAU catalytic films. When feeds representative of real reformate streams (containing CO
2 and H
2O) were fed to Pt-FAU coated reactors, the microreactor clearly outperformed the fixed bed reactor giving light-off temperatures that were lower by almost 50
°C. |
