Description
Greenhouse gas emission is a problem for the earth, and is causing warming
of the climate, and acidification of the oceans. The primary objective of
this project is to develop novel cobalt based catalysts, to enhance catalytic
conversion of CO2 by methane into, value added chemicals and fuels. The
heterogeneous Co-based bimetallic and tri metallic catalysts were synthesized
via a wet incipient impregnation method to uniformly coat the metal
salts to the pre-treated support (TiO2, SiO2, and La-ZrO2). 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 to determine selectivity,
conversion and stability of the catalysts. 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.
