Aromatic monomers obtained by selective depolymerization of the lignin β‐O‐4 motif are typically phenolic and contain (oxygenated) alkyl substitutions. This work reveals the potential of a one‐pot catalytic lignin β‐O‐4 depolymerization cascade strategy that yields a uniform set of methoxylated aromatics without alkyl side‐chains. This cascade cons...

Direct nonoxidative coupling is a promising route for methane upgrading, yet its commercialization is hindered by the lack of efficient catalysts. Pt/CeO2 catalysts with isolated Pt species have attracted an increasing amount of interest in recent years. Herein, we studied the catalytic role and evolution of isolated Pt centers on CeO2 prepared by...

Lignin‐derived monomers with methoxy substituents are abundantly present in bioliquids derived from lignocellulosic biomass. Examples are the products obtained from the reductive catalytic fractionation of lignin (RCF) and pyrolysis of lignocellulosic biomass and hydrotreated products thereof. An attractive valorization step for these liquids invol...

Fast pyrolysis is an efficient technology to convert lignocellulosic biomass to a liquid product. However, the high contents of oxygenated compounds and water hinder the direct utilization of pyrolysis oils. Here, we report an upgrading concept to obtain liquid products with improved product properties and enriched in valuable low molecular weight...

Rice husk is a kind of biomass feedstock with high ash content. The effect of acid washing (HCl, HF and H3PO4) on the inorganic contents in rice husk was analyzed in this study. The optimal pretreatment conditions for pyrolysis product distribution, including acid concentration, washing temperature and washing time, were investigated via pyrolysis–...

This study reports the stabilization of toxic heavy metals in fly ashes from incineration of municipal solid waste (MSW) in a grate furnace incinerator (GFI) and a fluidized bed incinerator (FBI) using wet milling without water-extraction pretreatment. After wet milling for 24 h, the relative leaching rates (RLRs) were decreased for all the studied...

Odorous sulfur-containing gases released during sewage sludge processing cause significant environmental pollution. This study investigates the effect of alkali addition on sulfur transformation as well as the release of the sulfur-containing gases during sewage sludge pyrolysis at 150-450 C. The presence of alkali can promote the transformation of...
