Impact of oxygen vacancies in Ni supported mixed oxide catalysts on anisole hydrodeoxygenation

نویسندگان

چکیده

The hydrodeoxygenation (HDO) activity of anisole has been investigated over Ni catalysts on mixed metal oxide supports containing NbZr and TiZr in 1:1 1:4 ratios. XRD patterns indicate the incorporation Ti (or Nb) into ZrO2 framework. XPS oxygen pulse chemisorption analyses reveal that Ni/Ti1Zr4 Ni/Nb1Zr4 possessed more vacancy sites than Ni/Ti1Zr1 Ni/Nb1Zr1, respectively. Correspondingly, HDO was higher with an conversion up to 30.7 34.4%, high selectivity towards benzene (up 64.7 63.3%), compared corresponding Ni/Nb1Zr1 catalysts.

Hydrodeoxygenation of Acetic Acid Using Monometallic and Bimetallic Catalysts Supported on Carbon

Heterogeneous catalytic hydrodeoxygenation (HDO) of biomass-derived feeds is a deoxygenation process that is of highly interest. Carboxylic acids are one of the main components of bio-oils and acetic acid (AA) is one of the most abundant of these carboxylic acids. This acid is rich in oxygen, therefore there is a lot of research for to produce fuel and other valuable chemicals such as ethanol. ...

Hydrogenation and Hydrodeoxygenation of 2-methyl-2-pentenal on supported metal catalysts

Platinum, palladium, and copper catalysts supported on precipitated silica have been studied for the hydrodeoxygenation and hydrogenation of 2-methyl-2-pentenal in the 200–400 C temperature range. The activity follows the order Pt > Pd > Cu. It has been found that at low temperatures, Pt and Pd are primarily active for the hydrogenation of the C@C bond to make 2-methyl-pentanal, with some decar...
