ABSTRACT:
The catalytic system MgO-?-Al2O3/TiO2-SO42- was synthesized, and then characterized by XRD, IR, NH3 - TPD, CO2-TPD, BET, EDX methods. As can be seen from the results of physical characterization, the synthesized MgO-?-Al2O3/TiO2-SO42- material owns a large surface area of 261.85 m2/g, a mean capillary diameter of 95.5 Å. The presence of TiO2 and SO42- creates strong acid sites on the catalyst surface, as indicated by the NH3 desorption temperature peak at 509.5°C and 546.6°C. The presence MgO phase creates strong basic sites, as specified by the CO2 desorption temperature peak at 502.1°C. A transesterification between methanol and waste cooking oil (the volume ratio of methanol to oil of 1:1) using MgO-?-Al2O3/TiO2-SO42- as a catalyst was carried out at 120°C for 4 hours. The reaction efficiency was about 98.1%.
