Robert Marriott

Dr. Robert Marriott is a Professor in the Department of Chemistry at the University of Calgary and holds the NSERC/ASRL Industrial Research Chair in Applied Sulfur Chemistry. He serves as the Director of Research at Alberta Sulphur Research Ltd. (ASRL), collaborating closely with their Core Research Program. His research focuses on high-pressure sour gas properties, applied sulfur chemistry, and industrial fluid systems. Key areas include optimizing gas conditioning in H2S-rich environments, ionic liquid applications, water-hydrocarbon solution chemistry (including hydrates), and elemental sulfur properties under industrial conditions. His experimental thermodynamic work addresses challenges in natural gas production and processing.

Research is conducted at the University Research Centre (URC) and supported by partnerships with industry leaders like ExxonMobil, Shell, and Husky Oil, alongside funding from NSERC. His group investigates acid gas adsorption on materials such as zeolites and silica gels, as well as the development of sustainable sulfur recovery methods. He leads the Marriott Research Group, emphasizing experimental physical chemistry and industrial relevance.

Dr. Marriott’s work spans collaborations with ASRL and academic grants, addressing issues like shale gas souring, hydrate dissociation conditions, and catalyst modification for sulfur conversion. His contributions include advancements in desiccant stability, ionic liquid applications for gas separation, and safety protocols for high-pressure hydrogen sulfide experiments.
