Title: Recent advances in hydrotreating of pyrolysis bio-oil and its oxygen-containing model compounds

Abstract

There is considerable world-wide interest in discovering renewable sources of energy that can substitute for fossil fuels. Lignocellulosic biomass, which is the most abundant and inexpensive renewable feedstock on the planet, has a great potential for sustainable production of fuels, chemicals, and carbon-based materials. Fast pyrolysis integrated with hydrotreating is one of the simplest, most cost-effective and most efficient processes to convert lignocellulosic biomass to liquid hydrocarbon fuels for transportation, which has attracted significant attention in recent decades. However, effective hydrotreating of pyrolysis bio-oil presents a daunting challenge to the commercialization of biomass conversion via pyrolysis-hydrotreating. Specifically, development of active, selective, and stable hydrotreating catalysts is the bottleneck due to the poor quality of pyrolysis bio-oil feedstock (high oxygen content, molecular complexity, coking propensity, and corrosiveness). Significant research has been conducted to address the practical issues and provide the fundamental understanding of the hydrotreating/hydrodeoxygenation (HDO) of bio-oils and their oxygen-containing model compounds, including phenolics, furans, and carboxylic acids. A wide range of catalysts have been studied, including conventional Mo-based sulfide catalysts and noble metal catalysts, with the latter being the primary focus of the recent research because of their excellent catalytic performances and no requirement of environmentally unfriendly sulfur. Themore » reaction mechanisms of HDO of model compounds on noble metal catalysts as well as their efficacy for hydrotreating or stabilization of bio-oil have been recently reported. This review provides a survey of the relevant literatures of recent 10 years about the advances in the understanding of the HDO chemistry of bio-oils and their model compounds mainly on noble metal catalysts.« less
