摘要

Abstract

Size-controlled Pd nanoparticles (PdNPs) were synthesized in aqueous solution

using sodium carboxymethyl cellulose as the stabilizer. Size-controlled PdNPs were supported on α-Al

by the incipient wetness impregnation method. The PdNPs on α-Al

support were in a narrow particle size distribution in the range of 1-6 nm. A series of PdNPs/α-Al

catalysts were used for the selective hydrogenation of acetylene in ethylene-rich stream. The results show that PdNPs/α-Al

catalyst with 0.03% (by mass) Pd loading is a very effective and stable catalyst. With promoter Ag added

ethylene selectivity is increased from 41.0% to 63.8% at 100℃. Comparing with conventional Pd-Ag/α-Al

catalyst

PdNPs-Ag/α-Al

catalyst has better catalytic performance in acetylene hydrogenation and shows good prospects for industrial application.
