This study investigates the formic acid-mediated hydrothermal carbonisation (HTC) of microalgae biomass to enhance green hydrogen production. The effects combined severity factor (CSF) and feedstock-to-suspension ratio (FSR) are examined on HTC gas formation, hydrochar yield quality, composition liquid phase. conversion Chlorella vulgaris was investigated in a CSF FSR range -2.529 2.943; 5.0 wt.% - 25.0 wt.%. Artificial neural networks (ANNs) were developed based experimental data model analyse process. results show that formation can be increased up 3.04 mol kg-1 by applying 2.433 12.5 reaction conditions. ANN (BR-2-11-9-11) describes process with high testing training performance (MSEz = 1.71E-06 & 1.40E-06) accuracy (R2 0.9974 R2 0.9781). enhanced H2 indicates an effective alternative production scenario at low temperatures using high-moisture-containing feedstocks.

Biomass Waste and Bioenergy Production: Challenges and Alternatives

Published: Jan. 1, 2024

Biomass waste utilization for bioenergy production has gained significant attention in recent years due to the increasing demand renewable and sustainable energy sources. wastes, including agricultural residues, forest food waste, municipal solid are considered a promising feedstock their abundance potential reduce greenhouse gas emissions. However, there various challenges alternatives associated with biomass use that need be addressed ensure its efficient utilization. This chapter provides an overview of related production. The include availability accessibility variability composition quality, logistical issues, technological limitations conversion processes. Additionally, environmental social concerns, such as land use, water socioeconomic impacts, economic viability policy frameworks also discussed challenges. Considering these challenges, several proposed. These advanced technologies, thermochemical biochemical processes, which can overcome traditional methods. Furthermore, using mixed feedstocks co-processing other streams enhance feasibility Integrated approaches, biorefineries circular economy concepts, use. highlights importance addressing exploring approaches consider technical, environmental, economic, aspects essential achieving from waste.
