Influences of various supports, γ-[Al.sub.2][O.sub.3], Ce[O.sub.2], and SBA-15 on HDO performance of NiMo catalyst

Hydrodeoxygenation (HDO) of guaiacol (GUA), has been carried out over γ-[Al.sub.2][O.sub.3], Ce[O.sub.2], SBA-15 supported NiMo catalysts in an autoclave at 250°C and a hydrogen pressure of 5 MPa. In comparison with NiMo/α-[Al.sub.2][O.sub.3], both NiMo/Ce[O.sub.2] and NiMo/SBA-15 catalysts showed t...

Description
Summary:Hydrodeoxygenation (HDO) of guaiacol (GUA), has been carried out over γ-[Al.sub.2][O.sub.3], Ce[O.sub.2], SBA-15 supported NiMo catalysts in an autoclave at 250°C and a hydrogen pressure of 5 MPa. In comparison with NiMo/α-[Al.sub.2][O.sub.3], both NiMo/Ce[O.sub.2] and NiMo/SBA-15 catalysts showed their higher activities. NiMo/SBA-15 has been found to be the most potential one for HDO of GUA with GUA conversion and HDO degree of 90 and 67.5 %, respectively. The main product was cyclohexane with its yield of 56 mol%. The outstanding activity of this catalyst results from a high dispersion of its active sites on SBA-15 as catalyst support. For Ce[O.sub.2] supported catalyst, some interactions of Ce-Mo can be occurred, leading to an enhancement of its HDO performance.
