SUSTAINABLE IMPROVEMENTS IN THE WOOD Fuel Pellet CHAIN
2014Co-Authors: Magnus Ståhl, Jonas Berghel, Helén WilliamsAbstract:A path towards sustainability should include growth with sustainable means such as the concept of Bioeconomy. The use of renewable resources for bioenergy should be performed to support sustainable development; however, biomass is made of limited resources and must be used efficiently and with a low environmental impact. The wood Fuel Pellet industry has the possibility to meet these criteria, but also has the potential for improvements. Earlier work on wood Fuel Pellet production has concluded that using oxidised cornstarch as an additive during Pellet production decreases the energy used and also produces Pellets with high durability. This work presents how additives such as cornstarch and molasses, affect the electricity use of the Pellet press and also affect the emission of CO 2 eq. from wood Fuel Pellet production. The results are presented for two different locations of the Pellet plant, since the results will depend on how the electricity used is produced, e.g. using more or less renewable or fossil Fuels in the electricity mix.

the effects of kraft lignin additives on wood Fuel Pellet quality energy use and shelf life
Fuel Processing Technology, 2013Co-Authors: Jonas Berghel, Magnus Ståhl, Stefan Frodeson, Karin Granstrom, Roger Renstrom, Daniel Nordgren, Per TomaniAbstract:Abstract In 2011, the total consumption of Pellets in Sweden amounted to 1.9 million tons, which represents an energy value of 9 TWh. The Pellets are used in large-scale as well as in small-scale applications, and increased demands on Pellet quality are likely to force Pellet producers to improve on the Pellet properties. One way of increasing Pellet quality is by using additives. The purpose of this article, therefore, is to examine kraft lignin as an additive. Pellets were produced in a small industrial Pellet press located at Karlstad University, Karlstad, Sweden, and 1–4% of kraft lignin was added to the Pellets. The results indicate that the addition of an increased amount of kraft lignin to the Pellets increases their mechanical durability and their lengths. The results also indicate that dry kraft lignin yields Pellets with higher durability as compared to wet kraft lignin. The energy demand was unaffected by the increased use of kraft lignin. The general results presented in this paper are useful for producers of lignin, Pellet producers and end-users of Pellets, who are interested in developing their products and/or improving the production processes.

High temperature X-ray diffraction study of the kinetics of phase separation in hypostoichiometric uranium–plutonium mixed oxides
Journal of the European Ceramic Society, 2014Co-Authors: Romain Vauchy, Renaud C. Belin, Anne-charlotte Robisson, Fiqiri HodajAbstract:Uranium–plutonium mixed oxides incorporating high amounts of plutonium are considered for future nuclear reactors. For plutonium content above 20%, a phase separation occurs, depending on the temperature and on the oxygen stoichiometry. Here, using an in situ fast X-ray diffraction device dedicated to radioactive materials, we evidenced a phase separation occurring during rapid cooling from 1773 K to room temperature at the rates of 0.05 and 2 K s−1 for two (U1−yPuy)O2−x compounds, with y = 0.28 and 0.45, under a reducing atmosphere. Optical microscopy reveals that the cooling rate impacts the microstructure of the Fuel Pellet by inducing severe macroscopic cracks. These results are important for using uranium–plutonium mixed oxides with high plutonium content as nuclear Fuels. Considering the associated issues, they dictate a cautious attitude when defining their conditions of fabrication.
