TL;DR: A new multi-stage kinetic model has been developed for TGA pyrolysis of arundo, corn stover, sawdust and switch grass that accounts for the initial biomass weight and the pre-exponential factor, activation energy, and reaction order.

TL;DR: A pilot-scale composting reactor was developed, manufactured, and tested to enhance the biologically heated drying of high-moisture ingredients while minimizing bulking amendment requirements as discussed by the authors, and three tests were run using poultry manure as a feedstock, once without and twice with sawdust amendment.
Abstract: A pilot-scale composting reactor was developed, manufactured, and tested to enhance the biologically heated drying of high-moisture ingredients while minimizing bulking amendment requirements. This biodryer consists of two horizontal cylindrical chambers with internal augers for mixing, materials transport, and aeration. Three tests were run using poultry manure as a feedstock, once without and twice with sawdust amendment. Manure was added to the biodryer sequentially, every other day during each 6-day experimental period. Moisture content, temperature, NH3 and H2S emissions, nitrogen, phosphorus, potassium, calcium, and seedling germination rate were analyzed throughout the experimental period. Results indicated that while sawdust was required to maintain aerobic conditions, sequential feeding was effective in reducing the amendment requirements by recycling the amendment through multiple batches of manure. Cumulative sawdust:manure volume ratios were reduced from 2.5:1 in the initial mixtures to 1:1 or...

TL;DR: In this article, a series of activated carbons were prepared from sawdust by zinc chloride activation in different operation conditions and the effects of operation parameters such as impregnation ratio, activation temperature and time on the adsorption properties of activated carbon were measured and analyzed in order to optimize these operation conditions.
Abstract: A series of activated carbons were prepared from sawdust by zinc chloride activation in different operation conditions. The effects of operation parameters such as impregnation ratio, activation temperature and time on the adsorption properties of activated carbons were measured and analyzed in order to optimize these operation conditions. The experimental results show that under the experimental circumstances studied, both the yield and the adsorption for iodine and methylene blue of activated carbon can reach a relatively higher value in the chemical activation process with the impregnation ratio of 100% ZnCl2/sawdust in the activation temperature of 500 °C carbonized for 60–90 minutes which are the optimum activation conditions in making wood activated carbon. The most important operation parameter in chemical activation with zinc chloride was found to be the impregnation ratio.

TL;DR: The ash content evolution of the torrefied product showed that its properties approached a steady state within 20min and the reduction in Sauter mean particles size was up to 20.3% and 28.2% for 0.25-0.5mm and 0.5-1.0mm sawdust, respectively.
