Life-cycle assessment of flash pyrolysis of wood waste
This work analyzes a process known as flash pyrolysis, which produces bio fuels using biomass for power generation. A life-cycle assessment of flash pyrolysis of wood waste was conducted to study whether a flash pyrolysis plant set up locally would be environmentally friendly. The results obtained show that the process of flash pyrolysis of wood waste is in fact environmentally friendly, and th...
متن کاملPyrolysis Kinetics of Physical Components of Wood and Wood-Polymers Using Isoconversion Method
Two hardwood species, namely red oak and yellow-poplar, were separated into their bark, sapwood and heartwood components. The samples were tested for calorific value, specific gravity, proximate analysis, mineral composition, chemical composition, ultimate analysis, and thermo-chemical decomposition behavior. In addition, the thermo-chemical decomposition behaviors of cellulose, xylan, and lign...
متن کاملKinetics of biomass catalytic pyrolysis.
The Coats-Redfern method was used to analyze the kinetic characteristics of biomass catalytic pyrolysis, indicating that it can be described by multi-step reactions, rather than as a simple first-order reaction. Friedman model-free calculations were used to describe the starting reaction types and the corresponding initial kinetic parameters. Finally, nonlinear regression of biomass catalytic p...
متن کاملThe effects of pine wood vinegar on the germination, growth and photosynthetic characteristics of cucumber
Wood vinegar is a substance, derived from cooling black carbon fire, which could be used instead of chemical materials in the agriculture industry as an organic compound. In order to study the effectiveness of pine wood vinegar on physiological and photosynthesis traits of cucumber, two experiments were conducted based on a completely randomized design with six treatments including 0, 1250, 200...
متن کاملScreening Corewood of Pine for Wood Properties
Conventional breeding requires long breeding cycles which limits selection intensity due to large tree sizes and high costs associated with assessing properties. In contrast very early selection offers a short cycle and assesses corewood which is the poorest wood in the tree. Young Pinus radiata trees were deliberately leant to produce separately opposite wood (OW) and compression wood (CW). Th...
