Synthesis and hydrodesulfurization properties of NiW catalyst supported on high-aluminum-content, highly ordered, and hydrothermally stable Al-SBA-15

Al-SBA-15 was prepared by adjusting the pH value during high-temperature hydrothermal treatment. Appropriate metal–support interaction combined with suitable acidity endowed the NiW/Al-SBA-15 catalyst with excellent hydrodesulfurization activity. Highly ordered mesoporous Al-SBA-15 with high aluminu...
