Development of Supported Zn-Cu Bimetallic and Zn-Cu-Mo Trimetallic

Heterogeneous Catalysts for Dry Reforming of CO2 with Methane

Global warming caused by greenhouse gas emission has been becoming

more of an issue as the years progress. CO2 and methane are two major

greenhouse gas and methane is a major component of the aboundant natural

gas. Combinng CO2 and CH4 in a single process to produce value added

chemicals is very desirable. The primary objective of this study is to develope

novel Zn based catalysts to enhance the reaction of CO2 with CH4. The

heterogeneous Zn-based bimetallic and trimetallic catalysts were synthesized

via a wet incipient impregnation method to uniformly coat the metal

salts to the pre-treated support (Ce-ZrO2). The catalyst was dried in the oven

at 80 degrees C for two hours before subjected to the furnace to calcine at 450 degrees C

for five hours. The synthesized catalysts are to be tested for CO2 dry reforming

with methane through a flow bed reactor with controlled CO2 and CH4

flow rate and on-line GC analysis to determine the catalyst performance

such as selectivity, conversion and stability. Catalyst characterization such

as Brunauer Emmett Teller (BET) surface area, pore size and volume, Transmission

Electron Microscope (TEM), X-ray photoelectron spectroscopy (XPS),

X-ray diffraction (XRD), and CO Chemisorption and Temperature Programed

Reaction (TPR) will be carried out at Brookhaven National Laboratory with

an aim to establish relationships between activity and properties. The fundamental

study will serve as great guidance for us to understand the reaction

pathway of dry reforming of CO2 with CH4.
