Tier II Canada Research Chair in Hydrogen and Catalysis
Dr. Josephine Mary Hill currently serves as the Canada Research Chair in Hydrogen and Catalysis in the Department of Chemical and Petroleum Engineering. She holds BASc and MASc degrees from the University of Waterloo and a PhD from the University of Wisconsin–Madison.
In 2014, Dr. Hill was among the first group of 91 scholars to join the College of New Scholars, Artists and Scientists, an organization launched by the Royal Society of Canada. In addition to several technical awards, she has also received accolades for her mentoring work including the Engineers Canada Award for the Support of Women in the Engineering Profession.

Dr. Hill’s research group’s key areas of interest are:
Catalytic Hydrotreating of Heavy Oil
Alberta has considerable heavy oil reserves but heavy oil is much more difficult to process than conventional oil due to its high viscosity, metals content, and sulfur content. With industrial collaboration, we are working to develop sustainable catalysts from the by-product petroleum coke, as well to develop better methods to characterize these porous carbon materials.
Biochar and activated carbon can be economically produced from waste biomass. Research is on-going to understand the microstructure and surface properties of these materials to maximize the adsorption capacity for removal of organic and inorganic pollutants in tailings ponds and fracking water.
Gasification is a process to convert solid materials into gaseous products in the presence of steam and/or sub-stoichiometric oxygen. The gaseous product can be converted to hydrogen or liquid fuels. Naturally occurring sources of catalysts (e.g., switchgrass) improve the gasification of coal and petcoke and the overall sustainability of the process, but present certain challenges. Activation is a sub-set of gasification and so we are applying our gasification knowledge to the activation of petroleum coke and biomass.
