Application of Salts Free of Chlorine as Inhibitors of Clays in Aqueous Drilling Fluids

Lucena D.V., Borges P.R., Amorim L.V., Lira H.L., UniversidadeFederal de Campina Grande, BR

At present, concern with the environment damage and the costs involved in the disposing of contaminated cuttings have led to find drilling fluids water based, but during the well drilling it is common the presence [...]

Modified Nanoclays: An Approach to Stabilizing Drilling Fluids Rheology at High Temperature

Abdo J., Haneef M.D., Sultan Qaboos University, OM

There is a lot heard about growing dearth of conventional oil reservoirs in recent times. The depletion of ‘easy oil’ is a major concern for the drilling industry that is urging the technologists to push [...]

Clean Coal by Oxyacidification

Gokturk H., Ecoken, US

US, China and many other industrialized economies rely heavily on coal for electricity generation. Unfortunately coal has become a controversial fuel due to various pollutants and carbon dioxide (CO2) generated during combustion. Regulated pollutants include [...]

Novel CNT-polymer Nanocomposites used in Oilfield for High Temperature, High Pressure Sealing

Ito M., Schlumberger, JP

A novel sealing system base on MWNT (multiwalletd carbon nanotubes) and polymer nanocomposites was developed for the use in the exploration and development of hotter, deeper reservoirs. Fully dispersed and better bonding are two critical [...]

Metal-doped Photocatalysts to Reduce Carbon Dioxide in Ethanolamine Solution for Methane Production

Wu H-Y, Wu J.C.S., Bai H., Wu H-Y, Wu J.C.S., National Chiao Tung University, TW

Photocatalytic reduction of carbon dioxide (CO2) to form valuable energy source of methane in the ethanolamine (MEA) solution is investigated in this study. The TiO2 photocatalysts were prepared by doping with nano-sized metals (Fe, Zn, [...]

Reducing Material Waste in Biodiesel Production through Multi-Energy Optimized Processing

Kropf M.M., The Pennsylvania State University, US

Multi-Energy Optimized Processing is a patented green chemical processing technique which substitutes focused energy for hazardous chemicals to achieve efficient fuel conversions. Applied to bio diesel production, this technology reduces material waste in the form [...]

Ageing of elastomeric composites with natural antioxidants

Masek A., Zaborski M., Institute of Polymer and Dye Technology, PL

The natural antioxidants which were added to ethylene-octene elastomer (polyolefin elastomer-Engage). Vulcanizates were then subjected to numerous ageing: weathering (climat of Floryda), UV (0,7 W/m2), thermo-oxidation ageing (1000C/10days) and thermal-shock (-600C/+1000C) as a function of [...]

Computational Studies on Mechanisms for the Organocatalytic Depolymerization of Poly(ethylene) Terephthalate

Jones G.O., Horn H.W., Wei D.S., Fukushima K., Lecuyer J.M., Coady D.J., Hedrick J.L., Rice J.E., IBM, US

Poly(ethylene) terephthalate (PET) is a widely used thermoplastic commonly found in packaging products and that constitutes a large percentage of total plastic refuse. We have examined the depolymerization of PET with alcohols and amines, a [...]

Novel Green Polymer Composites: Major Enhancements in the Crystallization Kinetics of Poly(lactic acid) and Mechanical Properties of Polypropylene Created via Solid-State Shear Pulverization

Brunner P.J., Torkelson J.M., Kane N., Northwestern University, US

Hybrids of polylactide (PLA) or polypropylene (PP) with microcrystalline cellulose (MCC) were created using a continuous, industrially scalable, and environmentally benign process called solid-state shear pulverization (SSSP). The PLA composite was subsequently melt-processed (MP) with [...]
