Article
Bitumen upgrading involves the hydroconversion of larger molecules that require catalyst supports with meso- and/or macropores for access to the active sites. In this study, various activation processes were studied to activate delayed petroleum coke, which is a by-product of oil sands bitumen upgrading and an inexpensive source of carbon. The petr...

The effect of zinc addition on the catalytic performance of Pd/Al2O3 catalysts for n-butane dehydrogenation at 500°C was studied. The catalysts were prepared by incipient wetness impregnation with 0.33 wt.% Pd and Zn/Pd ratios from 0 to 0.39, using aqueous solutions of PdCl2, ZnCl2 and Zn(NO3)2. The catalysts were characterized by X-ray fluorescenc...

The effect of zinc addition on the properties and characteristics of Pd/Al2O3 catalyst was studied. The catalysts were prepared with 0.33 wt. % Pd and atomic Zn/Pd ratios from 0 to 0.39 by incipient wetness impregnation of the support with PdCl2-HCl, ZnCl2 and Zn(NO3)2 aqueous solutions. Both fresh and calcined catalysts were characterized by X-ray...

Meaningful incorporation of Indigenous and local knowledge (ILK) in climate change mitigation and adaptation efforts is key to accelerating effective action plans. This study argues that community-based environmental monitoring (CBEM), if done properly, can be more effective in incorporating ILK than environmental impact and monitoring based only o...
Article
Hazards and Operability Analysis (HAZOP) is one of a dozen‐structured process hazards analysis (PHA) methodologies that assess risks associated with operating processes to mitigate their consequences. HAZOP applies to all six stages of process design from discovery to decommissioning. Industry massively adopted PHA methodologies as a consequence of...
Article
Tri-reforming of methane (TRM) emerged as an attractive approach for syngas production that combines the methane steam reforming (SMR), dry reforming (DRM) and partial oxidation (POX) reactions in a single process. The key merits of the TRM process are the ability to use flue gas directly in the process feedstock, the great flexibility to control t...
Article
Local perspectives can conflict with national and international climate targets. This study explores three stakeholder (community, provincial, and federal) perspectives on the Alberta oil sands as risks for a sustainability transition in Canada. In an ex-post analysis, we compared outputs from stakeholder consultations and energy-economy models. Ou...

Technological innovation is considered to be one of the key strategies to maintain the global temperature below 2 °C. Since emerging and low-income countries are now responsible for reducing greenhouse gases (GHGs) under the Paris agreement, there is an implied need to balance their development mandate and climate change policies. This chapter high...

The conventional one‐at‐a‐time strategy to evaluate catalysts is inefficient and resource intensive. Even a fractional factorial design takes weeks to control for temperature, pressure, composition, and stability. Furthermore, quantifying day‐to‐day variability and data quality exacerbates the time sink. High‐throughput catalyst testing (HTCT) with...

Transitions toward a low-carbon future are not only technical and economical, but also deeply social and gendered. The gendered nature of energy transitions is often implicit and unexplored. As a corrective, this paper explores energy pathways by applying concepts from innovations and gender studies. We examine gender perspectives and niche energy...
Article
This study evaluated for the first time the performance of CSP in a cocurrent down-flow packed column operating at pulsing flow regime. Packing performance was evaluated on a bench-scale absorber equipped with high-speed imaging and pressure gauges. Absorption experiments were conducted at 101.3 kPa using an 8 vol% CO2/Air mixture and a 22 mol% MEA...

Canada is one of the top ten greenhouse gas (GHG) emitters in the world, and of the nation’s total, the province of Alberta was the biggest emitter primarily due to the fossil fuel industry and power generation. Alberta is currently facing a challenge to reduce GHG emissions in line with Canada’s obligations to meet Paris Agreement goals. Additiona...
Article
There are millions of tonnes of petroleum coke stockpiled worldwide, but to take advantage of this potential resource, a better understanding of how to activate this feedstock with less waste is required. The impact of steam addition during chemical activation of petroleum coke with a high sulfur content (~6.5 wt%) was evaluated with two chemical a...
Thesis
The effect of non-oxidative treatments in the behavior of a Pd-Ag/α-Al2O3 catalyst used for the selective acetylene hydrogenation was studied. For the experiments, a sample prepared by excess wetness impregnation along with a reference Pd-Ag sample, were selected. The catalysts were characterized by X-ray fluorescence (XRF) elemental analysis, N2 a...

TIPPING+ will provide an empirical in-depth social science understanding of fundamental changes in sociodemographic, geographical, psychological, cultural, political, and economic patterns which give rise to Social-Ecological Tipping Points (SETPs), both positive and negative in relation to socio-energy regional systems. Such empirical and theoretical insights will shed new light on the interdependencies between changes in regional socio-cultural structures and the technological, regulatory and investment-related requirements for embracing (or failing to embrace) low-carbon, clean-energy and competitive development pathways in selected coal and carbon intensive case study regions (CCIRs). The overall goal is to understand why and under which conditions a given social-ecological regional system heavily dependent on coal and carbon-intensive activities may flip into a low-carbon, clean energy development trajectory – or on the contrary may fall into an opposite trajectory with all its negative implications. Towards this goal, main focus of TIPPING+ is the participatory co-production of knowledge on the driving forces and deliberate tipping interventions leading to the emergence of positive tipping points toward clean energy transitions in European CCIRs.
Project
This project aims to understand the principles of dual spinning disc reactor (DSDR). DSDR pyrolysis the solid biomass to bio-oil at an elevated temperature and short particle residence time. Particle residence time, particle temperature uniformity, particle diameter distribution inside the reactors will be investigated. Then the fast pyrolysis kinetics will be implemented into the multiphase flow model in ANSYS FLUENT. Once a full understanding of the DSDR is known, lab-scale DSDR will be fabricated and tested. The CFD model will be updated based on the experimental measurement of lab-scale DSDR to develop a pilot-scale reactor.
