Nanocrystalline Sample

Magnesium-aluminum spinel MgAl2O4 was synthesized by mechanical treatment of a mixture of hydroxides followed by treatment of the solution at 80 ° C and sintering at 850° C. The obtained nanocrystalline sample with a specific surface area of 100 m2/g were used for the preparation of composite solid electrolytes (1-x) LiClO4-xMgAl2O4. It was shown that conductivity increases with the spinel concentration and goes through a maximum of 1.35·10-2 S/cm at 150 °C for composite 0.3LiClO4-0.7MgAl2O4.

Atmospheric Distillation

Desulfurisation of atmospheric distillation gasoline and gas oil was performed by adsorption process on Fe/ bentonite. The adsorbent was characterized by determining the adsorption isotherms, specific surface area, pore volume and average pore diameter. Adsorption experiments of atmospheric distillation gasoline and gas oil were performed in continuous system at 280�320oC, 5 atm and volume hourly space velocities of 1�2 h-1. The efficiency of adsorption on Fe / bentonite was better at desulphurisation of gasoline versus gas oil.
