Experience
Post-Doctoral Research Associate
Apr 2013 - Feb 2014 (10 months, 1 day)
Full-time. Writing a literature review on the topic of oxy-fired cement kiln plants. Writing scientific papers. Helping PhD students carry out laboratory work. Peer-reviewing scientific papers.
Post-Doctoral Research Assistant
Jul 2013 - Sep 2013 (2 months, 1 day)
Full-time. Writing a literature review on the topic of CO2-utilisation within industry. Liaising with other consortium members. Attending workshops and giving presentations. Peer-reviewing scientific papers.
PhD Student
Sep 2008 - Dec 2012 (4 years, 3 months)
Full-time. Working in the Energy Engineering Group within the Department of Chemical Engineering at Imperial College London, I worked with delegates from Cemex UK to complete my PhD in sustainable cement manufacture and clean power generation. This was split 50/50 between laboratory work and theoretical studies. The laboratory work involved looking at the trace element content of limestone and sorbent used to capture CO2, as well as the trace element content of fuels used to heat the laboratory apparatus

The Calcium Looping Cycle for CO2 Capture from Power Generation, Cement Manufacture and Hydrogen Production
Chemical Engineering Research and Design
Calcium looping is a CO2 capture scheme using solid CaO-based sorbents to remove CO2 from flue gases, e.g., from a power plant, producing a concentrated stream of CO2 (∼95%) suitable for storage. The scheme exploits the reversible gas–solid reaction between CO2 and CaO(s) to form CaCO3(s). Calcium looping has a number of advantages compared to closer-to-market capture schemes, including: the use of circulating fluidised bed reactors—a mature technology at large scale; sorbent derived from cheap, abundant an
Investigation into potential synergy between power generation, cement manufacture and CO2 abatement using the calcium looping cycle
Energy & Environmental Science
Here, we report the preliminary results of an investigation into the effects on cement chemistry of using as a feed calcium oxide (CaO) which is the spent sorbent from a promising CO2 capture process, the calcium looping cycle.
Improvement of Limestone-Based CO2 Sorbents for Ca Looping by HBr and Other Mineral Acids
Industrial & Engineering Chemistry Research
The effects of mineral-acid doping on the long-term reactivity of limestone-based sorbents for CO2 capture was investigated in this work. Havelock (Canada), Longcliffe (U.K.), and Purbeck (U.K.) limestones were doped with a range of mineral acids (HCl, HBr, HI, and HNO3), and the effects of concentration were also studied. Doped samples were subjected to repeated cycles of carbonation and calcination in a fluidized-bed reactor. The experimental results showed that HBr and HCl as dopants with a 0.167 mol % d
Integrating Calcium Looping CO2 Capture with the Manufacture of Cement
Energy Procedia
This paper investigates the trace element content of calcium oxide sorbent after repeated cycles of calcination and carbonation in the presence of fuel combustion during the calcination step. The trace element content of the sorbent was measured using ICP-OES after a wet acid digestion procedure. The weight % of alite, the cement phase responsible for short-term strength of the cement, has been measured using XRD for cement prepared in the laboratory from single cycled and repeatedly cycled sorbent.
