Enhanced oil/gas recovery and CO2 storage |
Dr Xianfeng Fan

Materials and Processes |
Enhanced oil/gas recovery and CO2 storage are a displacement process at pore scale, in which oil and gas are displaced by water or CO2 in reservoir at pore scale, or water is displaced by CO2 in aquifers at pore scale. This displacement is controlled by pore structure, pore wettability, pore surface chemistry, fluid viscosity and interfacial interaction between pore fluids and pore surfaces. The displacement controls the pore connectivity, therefore oil/gas recovery and CO2 storage capacity. We investigate the displacement and the effect of various factors on the displacement at pore scale and core scale.

Materials and Processes |
Bubbling fluidization has been widely applied in process industries, such as power generation from coal, renewable energy production, gasification and pyrolysis. In this study, we attempted to predict solid flow patterns, solid and gas mixing, bubble behaviour in a bubbling fluidized bed based on operational conditions and bed design.

Development of UV and visible light active photocatalysts |
Dr Xianfeng Fan
|
Materials and Processes |
To address the need for effective vis response photocatalysts, we have synthesised WO3 and TiO2 nanowires to provide a fast transport channel for the photo-generated electrons which can retard the charge recombination. We are working on improving the visible activity of the catalysts through modifying the nanocomposites using metal (Ag, W, V, Fe, Ni) and non-metal (C, N, B, S) elements, and through the control over the microstructure or even over the crystal phase.

Development and Evaluation of Sustainable Technologies for Flexible Operation of Conventional Power Plants |
Dr Hannah Chalmers
|
Energy Systems |
The increasing amounts of renewable energy present on the national grid reduce C02 emissions caused by electrical power but they fit into an electrical grid designed for fossil fuels. Fossil fuels can be turned on and off at will and so are very good at matching variations in load. Renewable energy in the form of wind turbines is more variable (although that variability is much more predictable than most people think) and there is a need for existing power plants to operate much more flexibly to accommodate the changing power output from wind, tidal and solar power.

Measurement of pore wettability |
Dr Xianfeng Fan
|
Materials and Processes |
Pore wetting is a principal control of the multiphase flows through porous media. However, the contact angle measurement on other than flat surfaces still remains a challenge. In order to indicate the wetting in a small pore, we developed a new pore contact angle measurement technique to directly measure the contact angles of fluids and gas/liquid/supercritical CO2 in micron-sized pores under ambient and reservoir conditions in this study, as well as the effect of chemical functional groups on pore contact angle.

Modelling advanced adsorption processes for post-combustion capture |
Prof Stefano Brandani
|
Materials and Processes |
Carbon capture from power stations and industrial sources is an essential pillar in the effort of reducing greenhouse gas emissions in order to achieve the legally binding target set by the 2008 Climate Change Act of 80% reductions by 2050. The current state-of-the-art technologies for post-combustion capture (including retrofit options for existing plants) are based on amine scrubbers, but inherent energy requirements make this an expensive option and significant research is aimed at the development of next generation carbon capture processes that reduce the cost of capital equipment and the energy needed.
