Dr Ahmed Askalany, Ph.D. is one of the recognized experises in the field of adsorption applications in cooling and water desalinations. Even he has been classified as one of the best 15 scintiests allover the world according to the SciVal (Scopus) in the last 6 years. He has more than 50 published peer reviewed papers either in international journals or conferences. He has a Ph.D. in Mechanical Engineering under a joint superviison beteen Kyushu Universiy, Japan and Assiut Universiy, Egypt at 2014. Since that time he worled at different contries such as Egypt, Germany and UK. He is working as an assistant prof at the faculty of industerial educations, sohag university since 2014 until today. He finshed supervising four master thesises and one Ph.D. besides the ongoings. His interests are in the fields of adsorption cooling, heating and water desalination that can be worked with renewable energy applications.

Supported ionic liquid water sorbent for high throughput desalination and drying

2018-12-28 17:18:33 | Keywords Renewable Energy,

The composite material 1-ethyl-3-methylimidazolium methanesulfonate ionic liquid in Syloid AL-1FP silica shows unprecedented water vapor sorption equilibrium properties. Equilibrium data were recorded at different loads of ionic liquid in the silica support (from 1.8%w to 60%w). At loadings>1.8%w, all the composites show type 3 isotherm, therefore conserving the vapor-liquid equilibrium of the bulk ionic liquid/water binary system but with increased ... Read more

Mohamed Refaat Diab, Ahmed S. Alsaman, Adsorption desalination-cooling system employing copper sulfate driven by low grade heat sources

2018-12-28 17:15:52 | Keywords desalination,

In this study benefits of employing copper sulfate salt hydrate with water vapor as a new adsorption pair in thermally driven adsorption desalination-cooling systems (ADCSs) have been investigated. Adsorption characteristics (isotherm and kinetic) of copper sulfate/water vapor pair have been presented in this study within temperature range of 25-55°C. Sun-Chakraborty (S-C) and Dubinin- Astakhov (D-A) models have been used for ... Read more

A state of the art of required techniques for employing activated carbon in renewable energy powered adsorption applications

2018-12-28 17:51:48 | Keywords Adsorption,

This paper reviews, for the first time, the measurement adsorption characteristics techniques to facilitate optimal testing of the validity of adsorbent materials in adsorption applications. Thermo-physical properties, adsorption characteristics and modelling techniques are presented. The characterisation of material thermophysical properties includes true and bulk densities, specific heat capacity, surface area, pore volume distribution and thermal conductivity. The adsorption characteristics were ... Read more

Recycling brine water of reverse osmosis desalination employing adsorption desalination: A theoretical simulation

2018-12-28 17:41:25 | Keywords desalination,

Intake, pretreatment and brine disposal cost of reverse osmosis sea water desalination systems represent about 25% of total cost of the desalinatedwater. The present study investigates effect of reverse osmosis brine recycling employing adsorption desalination on overall system desalinated water recovery. The adsorption desalination produces dual useful effects which are high quality potable water and cooling effect. Reverse osmosis desalination ... Read more

Weather effect on a solar powered hybrid adsorption desalinationcooling system: A case study of Egypt’s climate

2018-12-28 17:49:45 | Keywords Water treatment, Renewable Energy,

Effect of employing solar hybrid adsorption desalination-cooling system (ADCS) at the Egyptian weather has been investigated using TRNSYS software employing meteorological data of Assiut city at Egypt. A theoretical model of a semi continues hybrid ADCS employing silica gel-water has been used. Maximum specific daily water production (SDWP) is found to be about 10 m3/ton of silica gel. Moreover, maximum ... Read more
