Biography

I am a Senior Research Fellow, I began my career at the University of Nottingham in 2008 and held a fellowship position at the British Geological Survey between 2014 and 2017. I obtained a PhD in 2008 and Master of Research (MRes) in 2004 both in Petroleum Geochemistry from the Department of Chemical & Environmental Engineering, University of Nottingham. I hold a NEEBOSH certificate in Environmental Management (2019) and a BSc in Chemistry (2001) from Delta State University, Abraka, Nigeria. My background is in Chemistry, Petroleum Geochemistry/Geochemistry, Environmental Science and Environmental Management. I am a member of the Low Carbon Energy and Resources Technologies Research Group

Expertise Summary

I am an expert in pyrolysis, in the past 15 years i have developed laboratory high water pressure pyrolysis for use in shale gas reserve estimation and artificial maturation of petroleum source rocks for oil and gas exploration in high pressured conventional petroleum reservoirs.

Current Research

My research focuses on the application of pyrolysis for low carbon energy production, biochar production, characterisation of biochar for its application to soil for CO2 sequestration from the atmosphere, and quantification/reconstruction of past natural global warming and, CO2 and methane emissions events.

We utilise hydrothermal carbonisation (HTC) for the conversion of biomass and organic waste to low energy carbon solid products (hydrochar) that can be used directly as solid fuels or pyrolysed further at higher temperature to produce biochar, and for biochar production we use direct carbonisation method (high temperature pyrolysis).

My work on biochar production and characterisation is part of a multidisciplinary greenhouse gas removal (GGR) research (Biochar Demonstrator), applying biochar on land for CO2 sequestration funded by BBSRC. Biochar comprises both labile carbon and stable carbon fractions, a key element of biochar regarding CO2 sequestration is based on the fraction of biochar that will be stable over a long timescale when applied on land. Our research uses hydropyrolysis to quantify the stable polycyclic aromatic carbon (SPAC) content of biochar (recalcitrant carbon) that is resistant to decomposition that can store carbon in the form of CO2 in soil.

I am currently applying our well established multi-step sequential high pressure pyrolysis method on North Atlantic Igneous Province (NAIP) rocks for the simulation of hydrocarbon and CO2 emitted during past magma intrusion into the NAIP to aid quantification and reconstruction of past natural global warming and, carbon dioxide and methane emissions events from North Atlantic gneous Province. This is multidisciplinary research on global warming reduction led by the University of Birmingham and funded by Natural Environment Research Council (NERC).

Past Research

I have investigated the mechanism of shale gas formation and how gas is stored within shale rocks in unconventional shale gas reservoirs and the effects of pressure on hydrocarbon (oil and gas) generation, source rock maturation and oil cracking to gas in conventional petroleum reservoirs using closed system high liquid water pressure pyrolysis technique, and also investigated biomass conversion to liquid hydrocarbon using liquefied solvent extraction method.
