The behaviour of ultrasonic wave propagation through liquid solution has become an important tool for studying physical and chemical properties of liquid solutions. The density, viscosity and ultrasonic velocity of of cholesteryl oleyl carbonate have been studied. From the experimental data various thermo acoustical parameters such as free volume, internal pressure and Rao’s constant and Wada’s...

low grade diasporic bauxite in the jajarm mine with an a/s (al2o3/sio2) ratio of 2.3 is not usable in the bayer process at jajarm alumina complex. due to the severe interlocking effect between the diaspore and aluminosilicate minerals (chamosite and kaolinite) and iron-containing minerals in a microcrystal matrix, the thermo-chemical treatment, which is independent from micro-mineralogy, was ch...

In consideration of physical and chemical properties of pure substances, speed of sound is one of important quantity which can used to calculate many of other thermo-physical properties such as isothermal compressibility, Joule-Thomson coefficient, isobaric heat capacity and etc. These thermo-physical properties are the main parameters in industrial and chemical processes. Development of accura...

The effects of ultrasonic and thermo-chemical pre-treatments on the methane production potential of anaerobic co-digestion with synthetic kitchen waste (KW) or fat, oil and grease (FOG) were investigated. Non-linear regressions were fitted to accurately assess and compare the methane production from co-digestion under the various pre-treatment conditions and to achieve representative simulation...
