Supported Polymetallic Catalysts by Self-Propagating Surface Synthesis

Supported polymetallic catalysts (5–15% wt% of active phase) for deep oxidation and hydrogenation were successfully prepared by Self-propagating Surface Synthesis (SSS) using metal nitrates as oxidants and urea as a fuel. Commercial granules of γ-Al 2 O 3 ; NaA, NaX, ZSM-5 zeolites; and silica gel w...

Description
Summary:Supported polymetallic catalysts (5–15% wt% of active phase) for deep oxidation and hydrogenation were successfully prepared by Self-propagating Surface Synthesis (SSS) using metal nitrates as oxidants and urea as a fuel. Commercial granules of γ-Al 2 O 3 ; NaA, NaX, ZSM-5 zeolites; and silica gel were used as supports. The synthesized catalysts were characterized by XRD, BET, and SEM/EDS. Catalytic behavior of the catalysts in a flow reactor was determined by gas–liquid chromatography, chemical analysis, and tested in deep oxidation of CO and propane as well as in hydrogenation of CO 2 to methane.
