Abstract

Pd-Re/SBA-15 catalysts with different Pd precursors were prepared by the impregnation method. N 2 adsorption-desorption, XRD, H 2 -TPR, TEM and NH 3 -TPD were used to characterize the physical and chemical properties of the catalysts. Pd-Re catalysts with different precursors showed different activities in the reaction of glycerol hydrogenolysis. 5Pd-5Re/SBA-15 with PdCl 2 as Pd precursor had higher activity than those with Pd(NO 3 ) 2 and Pd(OAc) 2 as precursors. The existence of Cl could affect the particle sizes, reduction behaviors and the acid properties of Pd-Re catalysts. [ABSTRACT FROM AUTHOR]

Abstract

Highlights: [•] ·Ru catalysts with HZSM5(X) were used during glycerol hydrogenolysis. [•] ·As the acid amount increased, the glycerol conversion and CH4 selectivity increased. [•] ·The acid amount and acid strength of HZSM5(X) affected the C C bond cleavage. [•] ·Loading Ru on HZSM5(X) could modulate the acidity and decrease CH4 selectivity. [ABSTRACT FROM AUTHOR]
