Resumen

Catalytic ceramic papers were developed by incorporating Pt-NaY zeolite to ceramic papers. The necessary mechanical strength was enhanced by the addition of natural borate compounds, which confer elasticity and resistance similar to those obtained using colloidal suspensions, which are the most commonly used binders. Pt-NaY zeolite was incorporated into ceramic papers either during the papermaking process or by spraying a zeolitic suspension on ceramic papers. The partial encapsulation of the faujasite by the sintering of the borate compound during the calcination step made catalytic ceramic papers less active toward the CO oxidation reaction than the corresponding traditional systems (Pt-NaY zeolite coated onto cordierite monoliths or the powder Pt-NaY faujasite). Light-off curves indicated that the activity of Pt-NaY zeolite was preserved when incorporating the zeolitic component by spray, in which case the CO oxidation reaction ran away at ca. 130 °C, and the total CO conversion was achieved at 150 °C, maintaining 100 % CO conversion for more than 90 h.
