A general review is presented concerning jointly the crystallographic structures and the solid-solid and solid-liquid transition temperatures and enthalpies in the pure normal alkanes, as well as the structural and thermodynamic behavior of their synthetic binary, ternary, and multinary model mixtures and of real petroleum waxes. A major part of the structural and thermodynamic data of the l…
The equilibrium solubility of aspirin in supercritical CO2 has been determined using a dynamic method. Measurements were performed at pressures ranging from (10 to 25) MPa and temperatures from (308.15 to 328.15) K. The effect of a polar cosolvent, acetone, on the solubility of aspirin in supercritical carbon dioxide was also studied. The results show that the addition of acetone produces up…
2-methoxyethyl acetate (MEA) can be used to decrease exhaust smoke as a new oxygenated additive of diesel. Several fuel blends which containing 10%, 15% and 20% MEA were prepared. The effects of MEA on engine’s power, fuel economy, emissions and combustion characteristics were studied on a single cylinder DI diesel engine. Under the same speed and load conditions, the maximum cylinder pres…

The specific cooling power (SCP) of adsorption chillers could be increased by employing zeolite coated, extended heat transfer surfaces in the generator. An experiment featured 50 annular aluminium fins, 76 mm diameter, each coated with 2 g of zeolite CBV901, and pressed onto a 10 mm bore aluminium tube. A large (4 kg), structurally stiff and easily fabricated casing enclosed the finned tube…
