Description
Combining the abundant natural gas and CO2 in a single process to produce
value added chemicals is very desirable. The primary objective of
this project is to develop novel Cu-based catalysts to enhance the catalytic
conversion of CO2 and methane. The heterogeneous Cu-based bimetallic
and trimetallic catalysts were synthesized via a wet incipient impregnation
method to uniformly coat the metal salts to the pre-treated support (ZrO2,
SiO2). The catalyst was dried in the oven at 80∞ 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.
