Nanoclay-modified asphalt materials: Preparation and characterization

The objective of this study is to review existing literature in the area of nano-modification of asphalt and proceed to apply nano-materials to asphalt to improve the performance. This study integrates literature review, preparation, and characterization of nano-modified asphalt materials. In the experimental testing montmorillonite, nanoclay at 2% and 4% by weight of asphalt was blended in asp...

Removal of Organic Pollutant from Water by Modified Bentonite

Adsorption of the Quaternanry Ammonium Salts on Bentonite

Sodium bentonite was subjected to the effect of two new homologue series of chlorides (alcoxymethyl) dimethyloctyloamonium chlorides and 3-alcoxymethyl-1-octylimidazole chlorides with the hydrophobic substituents of the same length. Morphology of the obtained modified bentonite was studied under scanning electron microscope [SEM] and the degree of adsorption of the ammonium salts was determined...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
