RISEvaluation of fast and slow pyrolysis methods for bio-oil and activated carbon production from eucalyptus wastes using a life cycle assessment approach
reported on the environmental impacts of eucalyptus wood valorization via slow or fast pyrolysis to produce bio-oil/AC, but the comparison between their environmental burdens using Life Cycle Assessment (LCA) is yet to be made and examined. Hence...
Hydrogen sensing properties of indium doped tin oxide thin films deposited by spray pyrolysis
In this article the effect of indium impurity on tin oxide layers sensitivity have been studied. Tin oxide thin films without
impurity and with different impurities are deposited by spray pyrolysis method and their structural layers have been...
INVESTIGATING THE EFFECT OF COPPER IMPURITY AND HEATING ON THE SURFACE MORPHOLOGY, NANOSTRUCTURAL AND OPTICAL PROPERTIES OF CU DOPED COBALT OXIDE THIN FILMS
Cobalt oxide thin films with different percentages of copper as doping material were deposited on glass substrates kept at 450°C by using spray pyrolysis method. Cu/Co mole ratios were selected as 0.0, 0.05, 0.1, and 0.15. For investigating...
Kinetic modeling of biomass pyrolysis in a bubbling fluidized bed reactor
A simple kinetic model is developed for biomass gasification in a bubbling fluidized bed (BFB) with steam as the fluidizing gas. The biomass pyrolysis is described by a two-step kinetic model in which the primary pyrolysis is modeled by three...
Transparent microstrip patch antenna based on fluorine-doped tin oxide deposited by spray pyrolysis technique
Transparent microstrip antenna with fluorine-doped tin oxide (FTO or SnO2:F) patch is studied here. The authors make use of spray pyrolysis technique to deposit FTO transparent patch on a Pyrex glass substrate. The deposited FTO patches show high...
Effect of process conditions on product yield and composition of fast pyrolysis of Eucalyptus grandis in fluidized bed reactor
The fast pyrolysis of eucalyptus wood was conducted in a continuous-feed fluidized bed reactor. The effect of pyrolysis temperature, nitrogen flow rate, biomass feed rate and biomass feed size was investigated. The results showed...
Adsorptive removal of CO2 on highly microporous activated carbons prepared from Eucalyptus camaldulensis wood: Effect of chemical activation
A series of activated carbons (ACs) were prepared from Eucalyptus camaldulensis wood by chemical activation with H3PO4, ZnCl2 at different impregnation ratios as well as by pyrolysis, followed by activation with KOH. The porosity characteristics...
