Description
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.
