摘要

Abstract

The dispersibility of active components in hydrodesulfurization (HDS) catalysts significantly influences the corresponding catalytic performance. In this study

sugar-based materials (glucose

chitosan

soluble starch

and corn starch) were utilized to prepare CoMo bulk HDS catalysts through a sugar foaming process. The foaming intermediates were analyzed using TG

FTIR

and Raman techniques to investigate the pyrolysis and carbonization process

revealing the presence of graphitic carbon in the 3DPG

3DPSS

and 3DPCS catalysts even after calcination in an air atmosphere. The catalysts were further characterized using SEM

XRD

TEM

low-temperature N

physical adsorption

and XPS. The 3DPSS catalyst exhibited a thiophene conversion of 94.8% at 360 ℃ and 1 MPa

which could be ascribed to its unique three-dimensional pore structure

high dispersion of MoS

(0.21)

and high fraction of Mo

(83.14%). This study demonstrates the potential of using the sugar foaming technique to develop highly efficient HDS catalysts and provides new insights into the relationship between the physicochemical properties of the obtained catalysts and their catalytic performance.
