Pelletized silica and amine composites for CO2 capture via adsorption

Knowles G.P., Vogt C., Chaffee A.L., Cooperative Research Center for Greenhouse Gas Technologies, AU

Solid amine sorbent powders are of broad interest to facilitate CO2 capture towards reducing atmospheric greenhouse gas. It is recognized, however, that pelletized rather powdered adsorbents are required for industrial adsorption separation processes. “Molecular basket” [...]

Theoretical Synthesis of Mixed Materials for CO2 Capture Applications

Duan Y., DOE-National Energy Technology Laboratory, US

Since the current technologies for capturing CO2 are still too energy intensive, to develop new materials that can capture CO2 reversibly with acceptable energy costs are needed. By combining thermodynamic database mining with first principles [...]

The Scale-up of Fluidized-bed Gasifier

Liu Z., Suda T., Narukawa M., Takafuji M., IHI Corporation, JP

Gasification is a good method to upgrade solid fuel. The fluidized-bed gasifier is widely used for the gasification of low-rank coal and biomass. IHI develops a fluidized-bed gasifier TIGAR(Twin IHI GAsifieR). It is important to [...]

Technical and Economical Feasibility of Pyrolysis of Kraft Lignin

Farag S., Chaouki J., École Polytechnique de Montréal, CA

This research project discusses the technical and economical feasibility of converting kraft lignin to value-added chemicals. Two pyrolysis techniques were implemented: conventional pyrolysis using classical heating and microwave pyrolysis using electromagnetic irradiation. The product distribution [...]

In situ transesterification of wet microalgae under acid catalysts

Lee J.W., Kim B., Im H., Korea Advanced Institute of Science and Technology, KR

Microalgae can be categorized to be the third generation of promising biofuel resources and can utilize carbon dioxide from flue gas as a nutrient source and accumulate lipids inside cells. They grow faster than any [...]

Fabrication and Design of Carbon Nanomaterials Based Scale Monitoring Smart Sensor Systems

Younes H., Jelbuldina M., Sofela S.O., Tizan L., Al Ghaferi A., Saadat I., Masdar, AE

Scale is the creation of inorganic soluble salts from aqueous brines during oil and gas production. The scale deposits at the internal surface of the pipelines under the supersaturation conditions. The deposition of the scale [...]

Inert, Corrosion Resistant CVD Coating for Oil and Gas Service

Mattzela J.B., Smith D., Yuan M., Higgins M., Barone G., SilcoTek Corporation, US

Estimates of the cost of corrosion within US industries often exceed $150 billion. Challenges within the often complicated production techniques of the oil and gas industry have led to increased efforts to control these costs. [...]

Development of New Surfactants for CO2 Foam Enhanced Oil Recovery

Nguyen Q.P., Ren G., The University of Texas at Austin, US

Sweep efficiency in CO2 enhanced oil recovery processes are major problem owing to the unfavorable mobility of CO2. One method of controlling CO2 mobility is through the use of foam. CO2 foam in the past [...]

Field Application of Nanoparticle-Based Invert Emulsion Drilling Fluids

Borisov A., Husein M., Hareland G., nFluids, CA

Abstract. Application of nanotechnology in drilling fluids for the oil and gas industry has been a focus of several recent studies (Zakaria et al. 2012; Contreras et al., 2014). Zakaria et al. (2012) developed a [...]

Multifunctional Nanocomposites for Oil and Gas

Sherman A., Powdermet Inc/Terves Inc, US

The ability to design and manufacture highly engineered multiphase materials enables the independent (actually interdependent) control over physical and mechanical properties, and kinetic response of structural materials. The production of "materials that do more" offer [...]
