2. Although felled wood releases carbon to the atmosphere in various steps, the fact that growing trees absorb carbon has led to different carbon-accounting approaches for wood use, producing widely varying estimates of carbon costs. Many approaches give the ...
18,19] was used. While the model simulates the full terrestrial carbon cycle, only the carbon pools and fluxes relevant to the purpose here are discussed. The simulation did not include agricultural land, thus the estimates will be potential rates. The model...

To prevent the brittleness of charcoal made from direct carbonization of natural wood, a simple treatment for delignification and hemicellulose removal is used, followed by carbonization. The resulting wood carbon sponge (WCS) presented compressive resilience. [102]. The carbonization step not only ...
Wood-decay (WD) fungi are of main importance for recycling wood components in particular carbon in biogeochemical cycles and can be used as biological tools to valorize wood biomass in energy or paper industry. Conversely, they cause considerable losses in silviculture, arboriculture, or viticulture ...
This study aims to synthesis meranti wood-based activated carbon (MWAC) for methylene blue (MB) dye removal from aqueous solution. The MWAC was produced via physiochemical activation method which involves potassium hydroxide (KOH) treatment, carbon dioxide (CO2) gasification and microwave heating. ...
This study shows that activated carbon products obtained from Sapelli and Ayous wood chips, which are wastes released into the environment, can be used as low-cost biosorbents for the removal of organic micropollutants in drinking water. 展开 关键词: Chips of wood Activated carbon Paraquat ...
Figure1ashows a schematic of the fabrication process of our flexible and durable wood-based TENG. The natural wood was firstly converted into flexible wood using a top-down two-step approach involving partially removal of lignin/hemicellulose from natural wood followed by hot-pressing. Then, the ...
To confirm the organic pollutant removal rate, we characterized the organic mineralization rate in the 70% overlap metamaterial catalyst water purification system by measuring the total organic carbon (TOC). The unmineralized organic pollutants decreased to 24.1% at 15 min and decreased to 18.8% ...
The carbonization of coal is essentially a process for the production of a coke (the carbonaceous residue) by thermal decomposition (with simultaneous removal of distillate) of organic substances (Speight, 2013): Corganic→Ccoke/char/carbon+liquids+gases ...
