Torrefaction is an efficient method to recover energy from biomass. Herein, the characteristics (mass yield, energy yield, physical, and chemical characteristics) of torrefied bamboo at diverse temperatures (200–300°C) were firstly evaluated by elemental analysis, XRD, and CP–MAS 13C NMR...

Current wet chemical methods for biomass composition analysis using two-step sulfuric acid hydrolysis are time-consuming, labor-intensive, and unable to provide structural information about biomass. Infrared techniques provide fast, low-cost analysis, are non-destructive, and have shown...

Dehydrated Xilinhaote lignite (XL) and Huolinguole lignite (HL) were depolymerized in supercritical methanol at 310°C and the resulting soluble reaction mixtures were analyzed with GC/MS. The results show that the GC/MS-detectable species can be classified into hydroxybenzenes (HBs), esters,...
