Since the advent of the computer tools, and the increasing performance of the apparatuses of diffraction of x-rays, the determination of the crystalline structure of the monocrystals, starting from the data of x-rays, ...
The objective of this study is to develop a complete mathematical model for simulation and optimization of catalytic reforming process. The model is developed from a base of fundamentalchemistry.
Catalytic reforming is ...
The primary goal of our works is the calculation method of simulating a gas separation (rectification).
tray by tray method allows us to control all parameters affecting influencing the process such as temperature, pressure ...
A part of the Algerian natural gas is destinated to the exportation, where it should be liquefied is a necessity; this last operation is possible except if we eliminate the CO2 which the natural gas contains.
The reduction ...
The ceramic products are extremely interesting in the field of the membrane supports because of their mechanical resistance, chemical inertia, long working life and thermal stability. Research is currently directed towards ...
Methanol is synthesized starting from the synthesis gas (CO + H2 +CO2), this last is obtained starting from methane CH4 and from the water vapor. Rough methanol product contains some undesirable compounds; this is why the ...
In recent years, the regulation of water quality has become increasingly strict. This is due to a growing social concern on the preservation of the environment. For this purpose, the environmental research has undergone ...
Many industries, such as plastics, and textile use dyes to color their products and also
consome substantial volumes of water .Due to their good solubility, synthetic dyes are common water pollutants and they ...
A determining of some properties of zeolites 3A, 5A, 10X, Y and 4A DG-TRISIV and the moisture content in natural gas of GL2/Z have been studied. After describing the dehydration process, the different zeolites were chosen ...
The present work is devoted to the study by diffraction of x-rays of the structure détermination in the organic compound with nonlinear optical properties, 5-(p-nitrobenzylidène)-2-thioxo-3-N(o.OEthylphénylthiazoline-4-one ...
