Hydrogen peroxide production in a pilot-scale microbial electrolysis cell
(Elsevier, 2018-09-01)A pilot-scale dual-chamber microbial electrolysis cell (MEC) equipped with a carbon gas-diffusion cathode was evaluated for H2O2 production using acetate medium as the electron donor. To assess the effect of cathodic pH ... -
Hydrogen Production and Utilization of Agricultural Residues by Thermotoga Species
(University of Waterloo, 2007-09-26)Abstract: Hydrogen can be a renewable energy source to replace conventional fossil fuels. Compared to current hydrogen production processes by consuming fossil fuels, biological hydrogen production has the advantage of ... -
Hydrogen Production by Desulfurococcus fermentans
(University of Waterloo, 2012-09-28)Desulfurococcus fermentans is a hyperthermophilic archaeon growing optimally at 82°C. This microorganism is an obligate anaerobe with optimal growth pH of 6.0. It is capable of producing H2 as an end metabolic product using ... -
Hydrogen Production From Catalytic Ethanol Reforming In Supercritical Water
(University of Waterloo, 2009-05-21)As a means to produce high pressure hydrogen in order to reduce compression penalty, we propose to reform liquid fuel (e.g., bio-ethanol) in supercritical water (pressure above 221 bar and temperature greater than 374°C). ... -
Hydrogen Production from Liquefied Petroleum Gas (LPG) by Oxidative Steam Reforming Over Bimetallic Catalysts
(University of Waterloo, 2011-06-30)Hydrogen is a promising renewable fuel for producing energy in transportation and domestic applications. This study investigates the production of H2 from reforming of liquefied petroleum gas (LPG). LPG is a mixture of ... -
Hydrogenation of crotonaldehyde in a trickle-bed reactor with forced on-off liquid flow

Hydrogenation of Nitrile and Olefinic Groups in Butadiene Rubbers
(University of Waterloo, 2014-07-15)Nowadays, traditional diene-based polymers cannot meet the demand for robust elastomers in many industries. Acrylonitrile butadiene rubber (NBR) is a widely used diene-based polymer as an oil-resistant elastomer and is ... -
Hydrogenation of unsaturated polymers in latex form
(University of Waterloo, 2005)Diimide generated from the hydrazine/hydrogen peroxide/catalyst system can be used to hydrogenate unsaturated polymers in latex form. As an economical and environmentally benign alternative to the commercial processes ... -
Hydrogenolysis of Carbon-Carbon Sigma Bonds
(University of Waterloo, 2015-05-22)The modification of benzylic quaternary, tertiary, and secondary carbon centers through Pd-catalyzed hydrogenolysis of Csp3-Csp3 σ bonds is presented. When benzyl Meldrum’s acid derivatives bearing quaternary benzylic ... -
Hydrogeochemical soil dynamics relative to topography for forested land units undergoing reclamation in a post-mined landscape in the Athabasca Oil Sands Region, Alberta
(University of Waterloo, 2017-01-25)Natural forest soils of the Western Boreal Forest rarely witness near-surface soil flushing events during the growing season due to the forest’s excessive evapotranspiration demands and large unsaturated zone storage ... -
Hydrogeochemical, Mineralogical and Microbial Processes Occurring in Old Sulfide-Rich Tailings
(University of Waterloo, 2015-09-30)The former Sherritt-Gordon Mine, located in Sherridon Manitoba, processed approximately 7.7 Mt of sulfide ore between 1931 and 1951. The Zn-Cu volcanic massive-sulfide ore body yielded Zn and Cu concentrates with minor ... -
Hydrogeochemistry and Trace Element Mobility in an Acidic High-Sulfide Tailings Impoundment After 40 Years of Oxidation
(University of Waterloo, 2024-01-25)Abandoned mine sites can create a legacy environmental contamination issue when the generation of acid mine drainage is allowed to continue with insufficient or absent remediation measures. The South Bay mine, a former ... -
The Hydrogeochemistry of a Constructed Fen Peatland in the Post-Mined Landscape in the Athabasca Oil Sands Region, Alberta, Canada
(University of Waterloo, 2016-09-28)Large areas of land within the Athabasca Oil Sands Region (AOSR) have been subjected to open pit mining to recover bitumenous oil sands. Following extraction, oil sands require the addition of solvents to optimize the ... -
Hydrogeologic Analysis of a Complex Aquifer System and Impacts of Changes in Agricultural Practices on Nitrate Concentrations in a Municipal Well Field: Woodstock, Ontario
(University of Waterloo, 2005)The Thornton Well Field, located in an area of dominantly (~80%) agricultural land-use, produces ~50% of the drinking water for the city of Woodstock. Since the mid 1990?s nitrate concentrations in some of the supply ... -
