Short Contact Time Partial Oxidation of Methane over 1.5% Pt/Al2O3 catalyst washcoated on ceramic monolith

Short contact time partial oxidation of SCPO CH4 to synthesis gas over 1.5%pt/Al2O3 catalyst was investigated. Cordierite honeycomb monlith was used as a substrate and have been coated with sol-gel catalyst made of Pt nano particles dispersed on alumina . the aluminum monohydroxyde bohemite sols were synthesized by hot hydrolysis / peptization of an aluminum alkixide yoldas process. techniques like X-ray diffraction XRD , BET,TPR,SEM,and TEM were used for characterizaiton. catalytic activity data were collected by feeding CH4/O2/N2 gas mixtures , at varying temperature 600 C to 900 C and residence time 4-12 milliseconds . results showed high selectivity toward synthesis gas and stable performance over the catalyst.
