The conductivity of a nanosilver emulsion of diesel fuel

Student Ali Ghafran from the Department of Chemical Engineering at the University of Technology delivered a lecture on
(Preparation and study of the properties and conductivity behavior of nanotubes of diesel fuel and nanoparticles for emission control applications)
The student explained that the fuel emulsion nanotubes (water in diesel), a stable dispersion system consists of diesel fuel, surface materials for surface tension, and Turmah. Because of its small droplet size (20-200 nm), a nanoparticle is a stable stable solution that is useful in reducing the composition of both nitrogen oxides and solid particles attached to the diesel engine. However, the fuel's ability depends heavily on the method of preparation and physical properties Chemical and stability of the emulsifier.
In this study, the nanotube emulsion was prepared by rotor-stator mixing using surface tensioning materials mixed with Span80, Tween20, Tween60, and Tween80. The response surface method was used to obtain nested variables to maximize the stability of the emulsion. The optimum conditions were found to be 12.5% of the water content in the HLB 5.7 and 3.25% of the surface tension. 3.15% of the mixing time was 15,000 cycles per minute and the mixing time was 35 minutes with pH 9.8. The emulsion had droplets less than 50 nanometers.
The characteristics of the performance, emission and combustion of a diesel engine using nano-emulsified petroleum gas were studied by adding different types of nano-solid minutes (such as cerium oxide, zirconium and titanium dioxide) with nano-emulsion in the weight ratios of 50 and 100 ppm.
