Gram-scale Ru-containing catalysts templated on structured mesoporous silica were synthesized using wetness impregnation under microwave irradiation. The catalytic properties for the hydrogenation of aromatic-rich feed were studied, and it was found that each material had its own advantage under specific operating conditions. The Ru/HNT and Ru/MCM-41/HNT catalysts showed the best performance for the removal of aromatics at temperatures of 60-100 degrees C and 60-80 degrees C, respectively, while maintaining the octane numbers.
Gram-scale Ru-containing catalysts templated on structured mesoporous silica of MCM-41 type reinforced with natural aluminosilicate halloysite nanotubes (HNT), as well as their analogues based on pristine halloysite, were synthesized by wetness impregnation under microwave irradiation. The structural properties and elemental composition of the catalysts were studied by TEM, XRD, TPR-H-2, and XRF. Textural characteristics were determined by low-temperature nitrogen adsorption/desorption. The catalytic properties in hydrogenation of aromatic-rich model feed and gasoline fraction were studied in batch reactors in the temperature range of 60-150 degrees C, under hydrogen pressure of 3 MPa, and a substrate/Ru molar ratio of 2000 for 3 h. Comparing the results of the catalytic tests, we can conclude that each material has its own advantage for the treatment of aromatic-rich feed under specific operating conditions. The Ru/HNT and Ru/MCM-41/HNT catalysts performed best in the 60-100 degrees C and 60-80 degrees C temperature regions, respectively, for the removal of aromatics, e.g. benzene, to meet ecological restrictions while retaining the octane numbers.
