摘要

Abstract

Excess crude glycerol derived as a by-product from biodiesel industry prompts the need to valorise glycerol to value-added chemicals. In this context

catalytic steam reforming of glycerol (SRG) was proposed as a promising and sustainable alternative for producing renewable hydrogen (H

). Herein

the development of nickel (Ni) supported on ceria-modified mesoporous γ-alumina (γ-Al

) catalysts and their applications in catalytic SRG (at 550-750 °C

(STP)) is presented. Properties of the developed catalysts were characterised using many techniques. The findings show that ceria modification improved Ni dispersion on γ-Al

catalyst support with highly active small Ni particles

which led to a remarkable catalytic performance with the total glycerol conversion (ca. 99%)

glycerol conversion into gaseous products (

) was significantly improved with the Ni@12Ce-Al

catalyst

representing nearly a 2-fold increase compared with that of the conventional Ni@Al

catalyst. In addition

the developed catalyst also exhibited comparatively high stability (for 12 h) and coke resistance ability.
