Pyrolysing agricultural crop residues and other biomass constitutes a newer method of transforming often difficult, waste materials into novel type soil amendment/additive. Simultaneously, this process also makes it possible to exploit part the energy released in production. Biochar, viewed as solid product pyrolysis, is remarkable, porous material, rich carbon. Two residues, such wheat barley straw, were selected for experimental studies. The results indicate that practical temperature...
Nonindustrial straw pellets should comply with limitations on the content of ash, chlorine, nitrogen, sulfur, and heavy metals, have a high melting temperature ash. To produce such pellets, properties can be improved by leaching. In known papers, completion chlorine washing-out was not controlled. Aims paper were to study ash solubility at leaching until removal make conclusion studied suitability for production nonindustrial pellets. achieved soaking heating 100 °C subsequent plug flow...
Alkanes are widely used as phase change materials (PCMs), especially for thermal energy storage (TES), due to their high capacity, stability, availability, and non-corrosiveness. However, the drawbacks of alkanes low heat conductivity cost. Our aim was explore alternative organic PCMs TES compare such compounds based on relationship between performance For this purpose, we analysed several commercially available products, including long chain alkanes, alcohols, monocarboxylic acid, amines,...
Two cost-effective packing materials were used for n-butyl acetate removal in lab-scale biofilters, namely waste spruce root wood chips and biochar obtained as a byproduct from gasifier. Three biofilters packed with chips: without (SRWC), similar one 10% of (SRWC-B) that impregnated nitrogen fertilizer (SRWC-IB) showed yet differing maximum elimination capacities 206 ± 27, 275 21 294 20 g m−3 h−1, respectively, enabling high pollutant efficiency (>95% at moderate loads) stable performance....
Huge amounts of agricultural residues or wastes represent an interesting lignocellulosic material which can be used for energy recovery by pyrolysis as alternative to incineration. Together with the production, biochar (solid residue), advantage a soil conditioner other applications such adsorbents, supporting principles circular economy. Here we studied effect torrefaction and temperature from 250 700 °C on composition properties gas four types agrowaste-derived materials: sunflower harvest...
