In-depth study on the synergistic conversion mechanism of iron ore with waste biochar for co-producing directly reduced iron (DRI) and syngas
Waste biochar and waste iron ore sintering dust were synergistically resourced to produce directly reduced iron (DRI) and combustible syngas in this study. A solid product with 92.45 % metallization ratio and a combustible syngas (65.69 % CO, 8.03 % CH4) with a yield of 1170.9 ml/g were obtained at 1000 C for 60 min […]

Eulerian CFD simulation of biomass thermal conversion in an indirect slow pyrolysis rotary kiln unit to produce biochar from recycled waste wood
Producing energy and higher value bio-products from waste wood recycled from construction and demolition (C&D) debris has been proposed as an economically viable opportunity in the biomass and bioenergy sectors. However, several challenges associated with the thermal conversion processes remain to be solved. This study introduces a 3D numerical simulation to study thermal conversion of […]

Effect of carbon dioxide on pyrolytic products characteristics and DOM binding heavy metals copper in sewage sludge biochar
In this study, a new method of calculation and comparison on pyrolysis products is introduced in a sealed tube furnace under different pyrolysis conditions, to explore the effects of carbon dioxide (CO2) as carrier gas on biochar characteristics. In general, the pyrolysis temperature exhibited a more significant impact on biochar characteristics than residence time. The […]

Evaluation of biochar and hydrocar energy potential derived from olive mills waste: The case of Montenegro
Three different waste streams from olive oil production from Montenegro are utilized energetically by hydrothermal carbonization (HTC – hydrochar) and pyrolysis (biochar). Pyrolysis experiments of three-phase olive mill solid waste (3POMSW) were conducted for different pyrolysis temperatures of 450, 550, and 700 degrees C and a residence of 60 min for each experiment. HTC experiments […]

Co-gasification of woody biomass and chicken manure: Syngas production, biochar reutilization, and cost-benefit analysis
Abstract The management and disposal of livestock manure has become one of the top environmental issues at a global scale in line with the tremendous growth of poultry industry over the past decades. In this work, a potential alternative method for the disposal of chicken manure from Singapore local hen layer farms was studied. Gasification […]
