Maximizing the potential of low-grade biomass. Using biomass torrefaction to produce high-quality biofuel with enhanced properties, including increased energy density, improved grindability, and hydrophobicity. This environmentally friendly method can help lower greenhouse gas emissions, lower logistics costs, and increase energy independence. Biomass torrefaction is a promising route if you're seeking for a sustainable solution to generate heat, power, or biofuels.
MICROSTRUCTURAL DEGRADATION DURING THE STORAGE OF
This study emphasizes how the quality and characteristics of biomass pellets are affected by prolonged storage while being transported. Our findings revealed considerable degradation as seen by increased porosity, weight gain, and the development of an interior crack network. These results have consequences for further thermochemical conversion and show that the supply chain's storage conditions are crucial for preserving the quality of biomass pellets as a source of bioenergy. To prevent the premature deterioration of biomass pellets, we urge the creation of stricter regulations.
THE EFFECT OF ENVIRONMENTAL CONDITIONS ON THE DEGRADATION BEHAVIOR OF BIOMASS PELLETS
Our study looked at how storage circumstances affected the physicochemical characteristics of biomass pellets, which are being used more and more as a renewable energy source. According to our findings, the pellets' quality can be seriously compromised by varying storage conditions, particularly abrupt variations in temperature and humidity. This shows that in order to realize the full potential of biomass pellets as a bioenergy source, stricter laws and measures are required to maintain the quality of biomass pellets during transit and storage.
BIOCHAR FOR HORTICULTURAL AND AGRICULTURAL APPLICATIONS
In order to produce biochar for horticultural uses, this study focuses on the torrefaction of agricultural and forestry leftovers. The project aims to determine the most appropriate biomass materials based on their characteristics and intended uses, and to assess the effectiveness of different torrefied biomass feedstocks for applications based on soil remediation and sequestration. According to physical and chemical characterization tests, our study finds around 50 different biomass feedstocks, rates the top 10 best-performing feedstocks for biochar applications based on soil remediation and sequestration, and analyzes each one.
THE VALORIZATION OF VOLATILES RELEASED DURING TORREFACTION OF VARIOUS KINDS
OF AGRICULTURAL BIOMASS
This work examines the importance of pretreatment and densification procedures, such as torrefaction and pelletization, in transforming biomass into solid biofuels. Our study explores different techniques besides combustion for reusing the waste streams created by the torrefaction of corn stalk and sugarcane bagasse. A total of four distinct valorization configurations were created and their efficiency and economics were examined; chemical looping combustion was found to be the most desirable choice. For torrefied maize stalk and sugarcane bagasse pellets, the results show great gross LHV efficiency and relatively low production costs.
TECHNO-ECONOMIC EVALUATION OF REFUSE DERIVED FUEL TORREFACTION
The need for energy has increased over the past ten years, yet the majority of it is still being fulfilled by non-renewable resources like coal, oil, and natural gas. The importance of increasing the proportion of renewable energy in the overall mix has increased awareness of refuse-derived fuel (RDF) as a substitute. Torrefaction is a promising way to raise the calorific value of RDF, but optimising its features is important to encourage its implementation. The torrefaction of RDF was evaluated techno-economically in this study, with the process parameters optimized and its economic viability assessed. Our findings indicated that torrefaction at 250°C for 30 min increased calorific value, and that employing torrefied RDF in a cement factory can greatly lower carbon dioxide emissions and the use of fossil fuels.
