Vapour phase hydrodeoxygenation of Guaiacol using Ni/SBA-15 for bio-oil upgrading
The primary aim of this study is to break down the methoxy (-OCH3) and hydroxyl(-OH) oxygenates present in lignin, a component of biomass. This degradation was performed on a lignin-derived model compound, guaiacol, using a highly effective Ni-loaded SBA-15 catalyst. SBA-15 was synthesized via a hydrothermal method, and varying amounts of NiO (5, 10, 15, 20, 25 wt%) were incorporated into SBA-15 through wet impregnation. The catalysts were characterized by using techniques such as XRD, DRS-UV, FT-IR, TPR, BET, SEM, and HR-TEM. Their catalytic performance was evaluated through the hydrodeoxygenation of guaiacol in a vapor phase reactor under controlled atmospheric pressure conditions. Notably, at 200 °C with a hydrogen flow rate of 50 ml/h, the 10 wt% NiO/SBA-15 catalyst demonstrated superior catalytic activity, achieving high guaiacol conversion and aimed product selectivity.
期刊介绍：
The Journal of Porous Materials is an interdisciplinary and international periodical devoted to all types of porous materials. Its aim is the rapid publication
of high quality, peer-reviewed papers focused on the synthesis, processing, characterization and property evaluation of all porous materials. The objective is to
establish a unique journal that will serve as a principal means of communication for the growing interdisciplinary field of porous materials.
Porous materials include microporous materials with 50 nm pores.
Examples of microporous materials are natural and synthetic molecular sieves, cationic and anionic clays, pillared clays, tobermorites, pillared Zr and Ti
phosphates, spherosilicates, carbons, porous polymers, xerogels, etc. Mesoporous materials include synthetic molecular sieves, xerogels, aerogels, glasses, glass
ceramics, porous polymers, etc.; while macroporous materials include ceramics, glass ceramics, porous polymers, aerogels, cement, etc. The porous materials
can be crystalline, semicrystalline or noncrystalline, or combinations thereof. They can also be either organic, inorganic, or their composites. The overall
objective of the journal is the establishment of one main forum covering the basic and applied aspects of all porous materials.
