Explosion reactivity characterisation of pulverised torrefied spruce wood

Liquefaction of Torrefied Wood using Microwave Irradiation

Torrefaction is an effective pretreatment method to improve the uniformity and quality of lignocellolosic biomass before further thermal processing (e.g., gasification, combustion). The objective of this study was to determine the impacts of torrefaction as a pretreatment before liquefaction. Wood chips were torrefied for 2 h at three different temperatures (230, 260, 290 °C) and then subjected...

Characterisation of Pulverised Palm Kernel Shell for Sustainable Waste Diversification

The paper presents a report on the physico-thermal properties and elemental composition of pulverized palm kernel shell to enhance its use in engineering applications. Clean palm kernel shell were dried, milled and screened to obtain particles 0.23 mm mean diameter. Experiments were conducted to evaluate the physical and thermal properties of the pulverized palm kernel shell and its differentia...

Characterisation of water-soluble galactoglucomannans from Norway spruce wood and thermomechanical pulp

Different fractions of water-soluble polysaccharides, all composed mainly of acetyl-galactoglucomannans, from native Norway spruce wood and thermomechanical pulp were isolated and characterised. About 65% of the mannose units in the glucomannan backbone were acetylated at either the C-2 or C-3 positions in a ratio of 2.2:1.0. Mainly the mannose units, but also some glucose units, were also part...

Nanostructure of cellulose microfibrils in spruce wood.

The structure of cellulose microfibrils in wood is not known in detail, despite the abundance of cellulose in woody biomass and its importance for biology, energy, and engineering. The structure of the microfibrils of spruce wood cellulose was investigated using a range of spectroscopic methods coupled to small-angle neutron and wide-angle X-ray scattering. The scattering data were consistent w...
