Abstract In search for greener building materials, geopolymer wood composites (GWC) were produced through alkali activation of fly ash, using pine and eucalypt particles. The study examined the influence grinding species hot water treatment particles on physical properties specific compressive strength GWC before after 200 cycles soaking drying. Ash-grinding affected particle size distribution,...

Through its industrial applications potential (i.e. drying, stress relief, structural modification for impregnation, bending and surface treatments to enhance coating), microwave processing could offer a powerful materialprocessing tool to wood industry. In order to scale up a microwave process, the development of the exploratory process to production scale has to be performed. This research ba...

• Quantitatively studied K-Capture by kaolin/coal fly ash at dust-firing conditions. K-capture reaction biomass combustion and K-salt feeding conditions was compared. Deposit probe inserted into reactor lively monitored deposit formation. Deposition propensity quantitatively with without additive addition. The deposition behavior when firing different (pulverized wheat straw, wood, bark, leaves...

This paper examines the formation of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/F) during oxidative pyrolysis of wood. Model lignocellulosic compounds and fractions isolated from wood serve to generate volatiles which then interact with copper-loaded surrogate ash to produce PCDD/F. The measurements indicate a preference for the formation of PCDF over PCDD in all ...

Garlic (Allium sativum L.) is a widespread crop in vegetable production. The popularity of garlic due to its bactericidal and antioxidant properties. Digestate wood ash are the by-products cogeneration plants. digestate rich nutrients, can provide large part nutrients needed by plant during growing season, as well improves soil structure. Wood contains small amounts phosphorus potassium strongl...
