Specification
High-quality monodisperse Cu2S nanocrystals (sizes from 2 nm to 20 nm) have been successfully synthesized by the reaction of copper stearate (CuSt(2)) and dodecanethiol (DDT) in 1-octadecene (ODE).
Preparation procedure of spherical Cu2S nanocrystals
· The mixture of 0.1576 g (0.25 mmol) of CuSt(2) and 5 mL of ODE in a 25 mL three-neck flask was heated to 200 ◦C under nitrogen flow.
· Then 0.0506 g (0.25 mmol) of DDT was injected into the reaction system, and the temperature was set at 190 ◦C.
· The color of the solution changed rapidly from clear to light yellow then deep burgundy after the initial addition of DDT, and dark brown colloid was obtained as final product.
· The resulting product was diluted with hexane and particles of Cu2S were precipitated by methanol subsequently.
A superhydrophobic coating composed of copper stearate (CuSA2) and porous ZnO nanoparticles was prepared by a simple spraying method. The water contact angle of the ZnO/CuSA2 superhydrophobic coating can be as high as about 161°, and it exhibits excellent superbuoyancy properties.
Spray coating of ZnO/copper stearate films
· CuSA2 (0.32 g) was dispersed in ethanol (25 mL) using ultrasonication process for 10 minutes.
· Then, different weight percentage of ZnO nanoparticles were added to the CuSA2 solution and allowed to ultrasound irradiation for 30 minutes using a probe type sonicator.
· The resulting green colored suspension was taken in a nebulizer bowl and sprayed on a pre-cleaned glass substrate (over a hot plate maintained at 60 °C) at a pressure of 4 psi. The coating process was performed at different time duration ranging from 30 seconds to 30 minutes.
· The spray coated films containing porous ZnO, submicron sized ZnO, and ZnO nanoparticles impregnated CuSA2 were mentioned as ZnO/CuSA2 coatings, submicron sized ZnO/CuSA2 coatings, and ZnO nanoparticle/CuSA2 coatings, respectively.
In-situ combustion (ISC) is an effective thermal enhanced oil recovery (EOR) process. Using copper stearate as a catalyst can significantly improve the performance of the heavy oil catalytic ISC process. The promotion effect of copper stearate on heavy oil ISC can be verified through porous media thermal effect cell (PMTEC) and combustion tube experiments.
· PMTEC experiments
PMTEC can be used to determine the catalytic activity and optimal concentration of copper stearate. Heavy oil PMTEC experiments were conducted using crushed core samples as porous media. With the addition of copper stearate, the temperatures of both LTO and HTO decreased, meaning fuels formed more easily.
· Combustion tube experiments
The combustion tube experiments were conducted in thin-walled stainless steel tubes with two welded flanges at the ends. In the combustion tube experiment, the improvement of ISC performance by copper stearate is mainly reflected in lowering the ignition temperature, lowering the H/C ratio, increasing the air-fuel ratio, increasing the recovery rate, and improving the in-situ oil upgrading.
