CO2 catalytic conversion into fuels and fuel-precursors using biomass-derived H-donors - LEVERHULME


Project Description

This experimental project will deal with the global challenge of mitigating CO2 emissions to the atmosphere, by using CO2 as a raw-material to produce fuels and fuel-precursors. It will involve the synthesis of materials, their characterisation and catalytic test under reaction conditions.

The hydrogenation of CO2 into oxygenates and/or hydrocarbons (methane, methanol or dimethyl ether) has been the most investigated routes to obtain fuels or fuel-precursors from this waste. However, this technology still faces some drawbacks: finding a sustainable hydrogen source and reduce the energy requirements for the chemical conversion of carbon dioxide.

The main goals of this project will be, thus, to develop heterogeneous catalysts with exceptional performance for the hydrogenation of CO2 in the liquid phase using sustainable H-donors obtained from renewable biomass sources, understand the behaviour of the catalysts and study the reaction mechanisms and kinetics involved. Catalysts will be optimised in order to achieve enhanced CO2 adsorption, high conversion and selectivity for the desired products and to be active at relatively low temperature.

Beyond conventional thermal catalysis, the project will also include the development and use of innovative and future emerging energy technologies for the catalytic activation of molecules, such as microwave radiation, ultra-sound, etc. These techniques will be used with the target of promoting heat and mass transfer.

A list of references has been included as a reading guide on this topic.

Selection will be made on the basis of academic merit. The successful candidate should have, or expect to obtain, a UK Honours degree at 2.1 or above (or equivalent) in Chemical Engineering or any related discipline, such as Chemistry, Materials Science.

Essential Background: Chemical Engineering, Reaction Engineering, Renewable Energy Engineering, Chemistry, Materials Science.

Knowledge of: Materials synthesis, materials characterisation, namely N2 sorption to determine textural characterisation, TGA, FTIR, XRD, gas chromatography, etc., reactor design and kinetics, heterogeneous catalysis.
Microsoft Office package (especially Excel).
