Brewer’s spent grain (BSG) is a large-scale agroindustrial waste that could be more efficiently utilized. this waste is composed of lignocellulosic material and so may serve as a good source of biomass for thermochemical conversion. the present study investigated the fluid dynamics behavior of mixtures of sand and BSG in a spouted bed to assess the viability of the thermochemical conversion of this biomass via fast pyrolysis. Fluid dynamics analyses were performed while varying the mass fraction of BSG (6–80%) and the static bed height (6.6–13.4 cm). Empirical equations for predicting the minimum spouting conditions and the mixing index were obtained using a regression technique, and the selected fluid dynamics parameters were employed in the spouted bed pyrolysis. the bio-oil resulting from this process was rich in phenolic compounds, various nitrogenated compounds (representing precursors for pharmaceuticals) and long-chain hydrocarbons. the products obtained from the analytical and spouted bed pyrolysis processes were also compared.

饮用水安全与人类的健康息息相关,水消毒是避免和减少水生病原菌威胁人类的关键手段。利用传统饮用水消毒技术灭菌时,存在产生具有“三致”作用的消毒副产物(Disinfection by-products,DBPs)的隐患,对于更安全饮用水的需求和科学技术的发展使得新的水消毒技术逐渐兴起。文章首先回顾了重要的传统消毒技术原理,并指出了其存在问题和局限。另外,从消毒的原理、应用、灭菌效果以及对生成DBPs潜能的影响等角度,重点探讨了光催化消毒、电化学消毒以及水力空化消毒等3种新兴的水消毒技术,并对未来饮用水消毒技术的发展和趋势给予展望。
