Cold heavy-oil production with sand (CHOPS) is a primary recovery process in unconsolidated heavy-oil reservoirs. The recovery factor typically ranges from 5% to 15% of the initial oil in place (OOIP). Approximately 90% of crude oil is left underground with considerable exploitation potential...

The ruthenium carbamate complex derived from 3-trimethoxysilyl-1- propyl amine and carbon dioxide was found to be a novel catalyst for the oxidative cyanation of aromatic and cyclic tertiary amines to corresponding a-amino nitriles in high to excellent yields by using hydrogen peroxide and...

Membrane-based processes have the potential to overcome the limitations of conventional hydrogen separation techniques such as high energy consumption and environmental concerns. Natural zeolite membranes have recently been shown to demonstrate apparent molecular sieving of H2 from H2/CO2...

Ecosystem models are important tools for diagnosing the carbon cycle and projecting its behavior across space and time. Despite the fact that ecosystems respond to drivers at multiple time scales, most assessments of model performance do not discriminate different time scales. Spectral methods,...

In any geological sequestration projects, monitoring and verification are essential components in ensuring storage integrity. Seismic methods are regarded as a feasible way to monitor the subsurface CO2 because of their sensitivity to a rock’s pore space content. Therefore understanding the...

Ecosystem models are useful tools for evaluating environmental controls on carbon and water cycles under past or future conditions. In this paper we compare annual carbon and water fluxes from nine boreal spruce forest ecosystem models in a series of sensitivity simulations. For each comparison,...

Challenges in the processing of minerals have been on the rise due to increasing low-grade ores which require to be finely ground to liberate valuable minerals. Low-grade ores like the ultramafic ores contain large amounts of gangue minerals which impacts recovery of the valuable pentlandite...

In this work, the phase behavior of Athabasca bitumen + CO2 and Maya crude oil + CO2 is briefed. A literature review is presented on the previous research works (mostly experimental studies) done on CO2 + heavy oil and similar mixtures. Important aspects of phase behavior such as type of phase...

Agricultural soils under long-term no till management have been well known to sequester atmospheric carbon in soil organic matter and to reduce emissions of greenhouse gases. Our study aimed at quantifying CO2 and N2O emissions from Black Chernozems and Gray Luvisols managed under long-term (~ 30...

The world energy demand is constantly increasing and fossil fuels are still by far the main energy resource that supplies the world energy consumption market, therefore increasing oil recovery from all types of reservoirs is an important matter. The burning of fossil fuels for energy purposes, on...
