NEW “Pd / ULTRA-THIN AMORPHOUS-OXIDE LAYER /ZSM-5” CATALYSTS FOR SELECTIVE FORMATION OF PROPANE FROM CO/H2

Abstract
Among new three types of “Pd / ultra-thin amorphous-oxide(La2O3, SiO2, or TiO2) layers / ZSM-5” catalysts, prepared by a two-stage attaching technique, the La2O3-coated ZSM-5 -supported Pd catalyst was found to be a selective catalyst for propane formation (68%) from CO and H2 at 543 K and 1.01 MPa.
