Comparison of high temperature chars of wheat straw and rice husk with respect to chemistry, morphology and reactivity
(Elsevier, 2016-03-02)
Fast pyrolysis of wheat straw and rice husk was carried out in an entrained flow reactor at high-temperatures (1000–1500) °C. The collected char was analyzed using X-ray diffractometry, N2-adsorption, scanning electron ...
Characterization and reactivity of soot from fast pyrolysis of lignocellulosic compounds and monolignols
(Elsevier, 2018-02-06)
This study presents the effect of lignocellulosic compounds and monolignols on the yield, nanostructure and reactivity of soot generated at 1250 C in a drop tube furnace. The structure of soot was characterized by electron ...
Potassium and soot interaction in fast biomass pyrolysis at high temperatures
(Elsevier, 2018-04-02)
This study aims to investigate the interaction between potassium and carbonaceous matrix of soot produced from wood and herbaceous biomass pyrolysis at high heating rates at 1250°C in a drop tube reactor. The influence of ...
Modeling the influence of potassium content and heating rate on biomass pyrolysis
(Elsevier, 2017-03-14)
This study presents a combined kinetic and particle model that describes the effect of potassium and heating rate during the fast pyrolysis of woody and herbaceous biomass. The model calculates the mass loss rate, over a ...
Removal of phenol and chlorine from wastewater using steam activated biomass soot and tire carbon black
(Elsevier, 2018-10-30)
This study aims to demonstrate a novel method for removing toxic chemicals using soot produced from wood and herbaceous biomass pyrolyzed in a drop tube reactor and tire pyrolytic carbon black. The influence of ash content, ...
Characterization and reactivity of charcoal from high temperature pyrolysis (800–1600 °C)
(Elsevier, 2018-09-22)
This study presents the effect of wood origin and heat treatment temperature on the CO2 reactivity, nanostructure and carbon chemistry of chars prepared at 800, 1200, and 1600 °C in slow pyrolysis reactors. The ...
Characterization of woodstove briquettes from torrefied biomass and coal
(Elsevier, 2019-01-18)
Using waste biomass materials offers the potential to reduce the greenhouse gas emissions from fossil fuels. Torrefaction is very useful for improving the fuel properties of biomass in order to better match those of coal. ...
Categorization of tars from fast pyrolysis of pure lignocellulosic compounds at high temperature
(Elsevier, 2019-04-11)
This study presents how the yields of different tar compounds from pure lignocellulosic compounds respond to the change in temperature and residence time. Experiments were carried out with a drop tube furnace in the ...
Prediction of fast pyrolysis products yields using lignocellulosic compounds and ash contents
(Elsevier, 2019-10-26)
The effects of lignocellulosic biomass composition on product yields and distributions were studied under high-temperature pyrolysis conditions (800–1250 C) in a drop tube reactor. Several types of biomass were studied ...
A review of Lean adoption in the Irish MedTech industry
(MDPI, 2022-02-17)
There have been many literature reviews carried out on Lean implementation in larger organisations with specific focus on the automobile industry. Lean implementation in the medical device industry has not been extensively ...
