Torrefaction is a thermochemical pretreatment that enhances biomass properties, improving energy density, decomposition resistance, and hydrophobicity, making it viable alternative as biofuel. This study performed thermodynamic assessment of the torrefaction process for urban forest waste, integrating experimental data with two-step reaction kinetic modeling to evaluate product yields properties using Aspen Plus software. The was modeled yield reactor, employing Peng–Robinson equation...
This paper evaluated steam and CO2-enhanced gasification of spent coffee ground (SCG) biomass, including energy exergy aspects focusing on hydrogen production. The waste-to-hydrogen (WTH) conversion was performed via (1000 °C) with a drop-tube-reactor investigating six different to biomass (SBR 0.5, 0.8 1.2) CO2 (CO2BR 0.09, 0.18 0.27) ratios. syngas production indicated clear improvement against O2/N2 an H2 yield increase up 69.21% 18.32% for mediums. analysis points out the SBR as optimum...
This study applied Life Cycle and Risk Assessment (LCRA) to characterize a sugar-energy refinery's operation, considering greenhouse gas emissions. The introduction of disturbances in mass or energy flows within LCRA enabled the simulation accidental hypotheses, with estimation their environmental impacts from an approach oriented final damage. A risk value was assigned each transient scenario (10, 30, 100% leakage), criteria defined for accepting losses, calculating probabilities...
The bottleneck of urban forest waste (UFW) as biofuel relies on surpassing its logistical management, feedstock supply, heterogeneity, and property drawbacks. This article proposes a hybrid approach based multicriteria decision methods (MCDM) response surface methodology (RSM) to optimize the definition UFW blends their torrefaction (temperature process time). First, physicochemical characteristics (proximate, ultimate, calorific) six wood wastes (Mangifera indica, Ficus benjamina,...
Waste-to-energy has gained momentum as a valorization pathway for resource-efficient strategies. Previous studies assessed the improvement of single biomass sources by torrefaction, evoking its potential in optimizing solid renewable fuel. However, commercial torrefaction expands, common feedstock will likely be biomasses blend. Therefore, property and their blends is required to elevate product value. This article proposes hybrid approach based on multicriteria decision methods (MCDM)...
