Abstract
The correlation between the physico-chemical properties of bare and Mo-doped nickel aluminate derived catalysts and product distribution during hydrogenolysis of glycerol with in situ produced hydrogen in continuous was investigated. Stoichiometric nickel aluminate spinel was synthesized via citrate sol-gel in a one-pot synthesis and subsequently doped it with 1 wt% Mo, using both sol-gel one-pot and impregnation methods. Catalytic runs were performed at 235 ºC/ 45 bar for 4 h TOS. The results indicate that Mo-doping increased the number of both metal and acid sites, leading to more selectivity towards deoxygenated products. 1,2-propylene glycol was the major liquid product, Mo/NiAl catalyst exhibited the highest yield (27%) and selectivity (39%). Post-reaction characterization revealed that leaching and oxidation of metals could potentially cause catalyst deactivation. 1 wt% Mo-doped nickel aluminate-derived catalysts possess potential for the selective production of 1,2-PG in a eco-friendly process through one-pot coupling H2 generation and hydrogenolysis reactions.
期刊介绍:
Applied Catalysis B: Environment and Energy (formerly Applied Catalysis B: Environmental) is a journal that focuses on the transition towards cleaner and more sustainable energy sources. The journal's publications cover a wide range of topics, including:
1.Catalytic elimination of environmental pollutants such as nitrogen oxides, carbon monoxide, sulfur compounds, chlorinated and other organic compounds, and soot emitted from stationary or mobile sources.
2.Basic understanding of catalysts used in environmental pollution abatement, particularly in industrial processes.
3.All aspects of preparation, characterization, activation, deactivation, and regeneration of novel and commercially applicable environmental catalysts.
4.New catalytic routes and processes for the production of clean energy, such as hydrogen generation via catalytic fuel processing, and new catalysts and electrocatalysts for fuel cells.
5.Catalytic reactions that convert wastes into useful products.
6.Clean manufacturing techniques that replace toxic chemicals with environmentally friendly catalysts.
7.Scientific aspects of photocatalytic processes and a basic understanding of photocatalysts as applied to environmental problems.
8.New catalytic combustion technologies and catalysts.
9.New catalytic non-enzymatic transformations of biomass components.
The journal is abstracted and indexed in API Abstracts, Research Alert, Chemical Abstracts, Web of Science, Theoretical Chemical Engineering Abstracts, Engineering, Technology & Applied Sciences, and others.
