Abstract 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 fiber) and two ligneous ones (eucalyptus and ...

Abstract Oxidative torrefaction is a noticeable technique for industrial-scale biochar production for fuel, soil amendment, and carbon storage due to its low technological and economic requirement. In this study, two microalgal biomass (Nannochloropsis Oceanica and Chlorella sp.) under the influences of different torrefaction parameters (i.e ...

Renewable Energy, 2022 Torrefaction in partially oxidative atmospheres is a non-traditional approach to the thermal pre-treatment of biomass. Despite the potential benefits arising from this compared to traditional torrefaction undertaken under costly inert atmospheres, the literature lacks data on the combustion and kinetic analyses of densified biomass torrefied under ...

Effect of oxidative torrefaction on high temperature combustion process of wood sphere
Fuel, 2021Abstract The present work studies the effects of oxidative torrefaction (OT) (200–290 °C, 0–8 vol% O2) on the combustion process of wood sphere in a single particle combustor (SPC, 1226 °C, 3.0 vol% O2, wet basis), together with such effects on the yield, reactivity and morphology of the high temperature produced char.

The reaction characteristics of four biomass materials (i.e. oil palm fiber, coconut fiber, eucalyptus, and Cryptomeria japonica) with non-oxidative and oxidative torrefaction at various superficial velocities are investigated where nitrogen and air are used as carrier gases. Three torrefaction temperatures of 250, 300, and 350 °C are considered.

Influence of air oxidative and non-oxidative torrefaction on the chemical properties of corn stalk
Bioresource Technology, 2021The non-structural components (extractives and ash) in biomass can affect the torrefaction characteristics. The objective of this study was to investigate the applicability of air oxidative and non-oxidative torrefaction for corn stalk, which has higher organic extractives and lower ash contents.
