چکیده
Sulfur compound content in fuels is one of the most undesirable pollutions regarding standard environmental regulations that demand to reduce sulfur concentration limit 5-10% fuels. Hence, kerosene’s oxidative desulfurization (ODS) as a model fuel (sulfur 1158ppm) with air an oxidant studied. The goal study use two different synthesized nanosilica-supported catalysts, CuO/SiO2 (CAT-1) and CuO/TiO2-SiO2 (CAT-2), for ODS kerosene. Thirty-two experimental runs were designed via Central Composite Design (CCD) select experiments will be utilized efficiently. analysis variance (ANOVA) was used statistical determine models’ significance. Response surface methodology (RSM) optimum conditions parameters significantly affecting response. Temperature time are variables studied due their impact on desulfurization. actual results conversion kerosene from lab 87% 153.3ppm 99.22% 8.9ppm by CAT-1 CAT-2, respectively, at 140°C 100min. predicted design 86.66% 99.8% CAT-2 100min, showing errors less than 3.1% 1.2% ANOVA. optimal determined through maximization numerical optimization showed maximum 99.5% 140 min 180°C, 99.7% 100.1 140.1°C. Also, rate data fitted empirical kinetic model. activation energies Ea= 28.2 kJ/mol 38.7 kJ/mol, respectively.
