Thermal behavior of biomass in torrefaction plays an important role in the operation of pretreatment. To understand the endothermic and/or exothermic characteristics of biomass in the course of torrefaction, an experimental system is conducted and two kinds of biomass (oil palm fiber and...

The performances of thermal-concentrated solar thermoelectric generators (TEGs) at three different geometric types are investigated numerically to aid in designing practical devices. The temperature-dependent properties of the commercial thermoelectric material are taken into account, and an...

Biomass based oxygenated fuels have been identified as possible replacement of fossil fuel due to pollutant emission reduction and decrease in over-reliance on fossil fuel energy. In this study, 4v% water-containing ethanol was mixed with (65–90%) diesel using (5–30%) biodiesel (BD) and 1v%...

In recent years, torrefaction, a mild pyrolysis process carried out at the temperature range of 200–300 °C, has been considered as an effective route for improving the properties of biomass. Hemicellulose, cellulose, lignin and xylan are the basic constituents in biomass and their thermal...

The improvement on physical and chemical properties of pulverized biomass from torrefaction is investigated to evaluate the potential of biomass as solid fuel used in boilers and blast furnaces. Three biomasses of bamboo, banyan and willow are considered. The results indicate that when the...

The properties of biomass can be improved via torrefaction, and torrefied wood is a fuel with the potential to partially replace coal. In this study, raw Cryptomeria japonica (WRaw) is torrefied at 250 (TW250) and 300°C (TW300) for 1h, and then mixed with an anthracite coal to undergo...

Oxidative torrefaction is a method to reduce the operating cost of upgrading biomass. To understand the potential of oxidative torrefaction and its impact on the internal structure of biomass, non-oxidative and oxidative torrefaction of two fibrous biomass materials (oil palm fiber and coconut...

A method of producing hydrogen and syngas from the interaction of activated carbon, steam and carbon dioxide is conducted in the present study, where the interaction combines the solution loss reaction and steam gasification reaction. Two important parameters of reaction temperature and...

Sprays are an important tool for carbon dioxide capture through absorption. To figure out CO2 capture processes in sprays, the gas absorbed by a single droplet under droplet mutual interaction is investigated. In the study, the number density of droplet is in the range of 103–106cm−3. By...

Three agricultural wastes, consisting of coffee residue, sawdust and rice husk, undergoing torrefaction are investigated to evaluate the potential of biomass as solid fuel. Two different torrefaction temperatures (240 and 270°C) and durations (0.5 and 1h) are considered in the study, and the...
