65 Citations | • Durability of torrefied pellets is problematic compared to wood pellets. |
288 Citations | At such cost levels, torrefied pellets would become competitive with traditional pellets. |
110 Citations | There are promising technical possibilities for greater torrefied biomass use in a number of other areas such as the steel, non-metallic minerals, as well as the pulp and paper industries. |
138 Citations | The results showed that the density and the hardness of torrefied pellets mainly depended on the densification die temperature and the weight loss of torrefied samples. |
| Cofiring torrefied pellets in large-scale coal plants can be cost-competitive to industrial wood pellets, when no additional retrofit and operation and maintenance costs incur. | |
104 Citations | However, densification processes such as pelletisation is necessary to improve the tradability of “low-dense” torrefied biomass. |
01 Feb 2018 | With the improvement in the properties, torrefied biomass mainly has three potential applications: combustion or co-firing, pelletization and gasification. |
110 Citations | Torrefied biomass has considerable potential as a biomass fuel to replace coal in energy and process heat production. |
| In order to produce wood pellets with desired physical and thermal characteristics, a suitable additive with the right biomass material should be used. | |
104 Citations | Torrefied biomass represents a high quality renewable energy commodity that can be used to substitute fossil fuels such as coal. |
| However, several limitations to its utilization for pellets production may arise since they are already put to other uses, such as biomass power plants. | |
| Among the various options, the use of mixed biomass pellets is becoming remark-able due to the wide variety of species, although more research is needed in order to enhance the mechanical properties of these pellets. | |
864 Citations | When torrefied sawdust is compressed into torrefied pellets, more mechanical energy is consumed and higher die temperature is required to make torrefied pellets of similar density and hardness as regular pellets. |
89 Citations | Results showed that torrefied sawdust particles prepared under typical torrefaction conditions (280–300°C for 10–30min) could be made into strong pellets by compression at a die temperature higher than 220°C or by introducing biomass binders such as untreated sawdust, starch or lignin at a lower die temperature. |
65 Citations | From the results the following statements can be made regarding produced pellet samples: • Feedstock choice has a strongly influence on properties of torrefied pellets. |
| In view of the lower density, lower hardness, lower volumetric energy density, and energy yield of torrefied pellets, it is recommended that biomass should be torrefied and then compressed to make strong pellets of high hydrophobicity and volumetric energy density. | |
| The compression force was lower in the pellets torrefied at 250 °C with approximate loads of 700 N. Based on the above results, it was concluded that pellets made with biomass torrefied at 200 °C have better energy properties and evaluated properties. | |
| Elemental analysis of torrefied biomass material showed increased carbon content, indicating higher heating values of torrefied pellets over non-torrefied biomass. | |
65 Citations | • Logging residues do not seem to be an optimal feedstock choice for torrefied pellets. |
| Furthermore, the study illustrates that factorial experiments using single-pellet devices provide new insights that are of importance for the next generation of pelletizing of torrefied biomass. | |
| Torrefied biomass is a more desirable feedstock for co-firing applications, especially in existing coal-fired power plants. | |
| The results revealed substantial differences among the samples, mainly regarding their moisture content, higher heating value, and energy density in torrefied pellets. | |
89 Citations | Torrefied pellets are expected to have distinct applications in power generation and help coal-based utilities to reduce their emission levels and comply with increasingly stringent regulations. |
104 Citations | The results showed that it was difficult to bind the torrefied biomass particles and a binding agent was necessary to enable their effective pelletisation with reasonable energy consumption. |

What are the most common types of non-enzyme proteins found in crop residues?5 answersNon-enzyme proteins found in crop residues include swollenins, expansins, and loosenins, which lack hydrolytic activity but aid in the decomposition of lignocellulosic biomass by disrupting cellulose chains' hydrogen bonds, facilitating enzymatic hydrolysis. Additionally, microbial proteins derived from agricultural lignocellulosic residues, such as wheat straw, offer a sustainable alternative to traditional plant- and animal-sourced proteins, with Fusarium venenatum efficiently converting these residues into microbial protein. These proteins play a crucial role in addressing the challenge of providing sustainable protein sources, especially in the face of increasing protein demands and environmental concerns associated with conventional protein sources.
What is volatile matter in biomass during torrefaction significant?4 answersVolatile matter in biomass during torrefaction is significant due to its role in energy recovery and fuel properties enhancement. Torrefaction, a mild pyrolysis process, reduces the hemicellulose content of biomass, leading to the generation of volatile products. These volatiles, which include condensable gases, can be utilized as an auxiliary energy source for feedstock drying and torrefaction processes, contributing to energy recovery and supplementing the energy required for torrefaction. Moreover, torrefaction increases the calorific value of biomass by devolatilizing water and oxygenated compounds, enhancing its energy content on both mass and volumetric bases. The decrease in volatile matter content during torrefaction enriches the lignin content of the biomass, making it a more suitable feedstock for energy production.
What is seed pelleting?5 answersSeed pelleting is a technique used to enhance seed quality and performance by coating seeds with various materials. This process involves applying coatings such as clay, cellulose, gum, and microorganisms to seeds, providing benefits like improved germination, seedling growth, and protection against pests. Pelleting can increase seed size, shape, and uniformity, facilitating precision seeding and allowing for the incorporation of fertilizers and protective agents within the seed coat. Additionally, seed pelleting coatings can include layers for moisture absorption, water retention, and disintegration, controlling germination time, increasing germination rates, and extending seed storage life. Specialized equipment like seed pelleting machines are utilized to carry out this process effectively.
What is the potential market of organic feeds pellet?4 answersThe potential market for organic feeds pellets is significant, particularly in the context of renewable energy sources and clean energy production. In Mexico, biomass pellets produced from agricultural and forest residues have the potential to become a sizable low-carbon, renewable energy source that can compete with and substitute fossil fuels in specific economic sectors. The estimated market energy potential for pellets from currently available residues in Mexico is between 131 and 233 PJ/yr, with competitive costs compared to fossil fuels. Additionally, organic aquaculture products, including organic feeds, are gaining importance in the market as the demand for healthy and eco-friendly food products increases. The development of organic farming and the increasing number of organic product farms contribute to the growing market for organic feeds pellets.
What are some of the most common pelletized agricultural residues?5 answersThe most common pelletized agricultural residues include olive and vineyard pruning residues, canola meal and oat hull, and corn residues such as corncobs and corn husks. These residues are densified into pellets to enhance their handling and use. Other agricultural residues that can be pelletized include corn residueand various grain crops such as corn, rice, and wheat. These residues have different compositions and properties, such as cellulose, hemicelluloses, lignin, caloric value, and ash content, which make them suitable for energy utilization. The pelletization process improves the bulk approach, storage, and transport properties of these residues, making them more suitable for various applications in the industry.
