The sulfuric acid-catalyzed conversion of paper wastes in gamma-valerolactone (GVL) or dioxane leads to the formation levulinic acid (LA) and formic (FA), which can be converted GVL by transfer-hydrogenation using Shvo catalyst situ separately. isolation LA FA was assisted neutralization with ammonia form a biphasic system. While ammonium sulfate most some were aqueous phase, organic solvent-rich phase contained FA. used as an illuminating liquid glass lamps for hours without noticeable...
Possible utilization of SRF (solid recovered fuel) in the energy industry is a widely investigated topic, because even though it economically feasible, its complex reactions make steady operation hard to maintain. prepared as mixture well-combustible (but not recyclable) parts municipal and industrial waste, which consists mainly various papers, plastics textiles with very different combustion characteristics. To describe kinetics sample like this, more advanced methods recommended. In this...
Abstract The utilization of challenging solid fuels in the energy industry is urged by environmental requirements. combustion kinetics these fuel particles differs markedly from that pulverized coal, mainly because their larger sizes, irregular (nonspherical) shapes, and versatile internal pore structures. Although intrinsic reaction kinetic measurements on very small amounts finely ground samples are mostly available, a bridge toward apparent modeling not evident. In this study, method...
Abstract The utilization of challenging solid fuels in the energy industry (especially ones derived from wastes) has a big priority nowadays, as it is valid option to keep recent EU directive related decrease landfills. However, there are serious technical challenges, connecting lack knowledge about behavior these combustion chamber. This paper discusses specific aspects developing particle models concerning non-conventional fuels. A new modeling approach presented, using which possible...
Binary fuels of a fluidized bed combustor or gasifier are solids composed two groups particles. Their optimal handling in the same becomes rather difficult if their hydrodynamic properties differ by orders magnitude more. Both these fuel classes directly fed into reactor most cases but homogeneous originally switches binary character inside some others. A typical example latter case is thermal utilization rubber wastes. novel design proposed present paper setting up non-mixing,...
