In order to develop a suitable reactor for the biomethanation of high-strength salty cheese whey, the performance of anaerobic
upflow fixed-film reactors packed with different support materials, such as charcoal, gravel, brick pieces, pumicestones,
and PVC pieces, has been studied. The charcoal-bedded reactor gave the best performance, with the maximum gas production (3.3
L/L digester/d) and an enriched methane content (69% CH4). Temperature and hydraulic retention time were optimized, with the ultimate aim of improving biomethanation. Maximum gas
production (3.3 L/L digester/d) was achieved at a hydraulic retention time of 2 d at 40°C. 相似文献

A rapid and highly efficient methodology for the synthesis of 3-methyl-4-(hetero)arylmethylene isoxazole-5(4H)-ones has been developed using sulfated polyborate as a catalyst. The multicomponent reaction of an aromatic/heterocyclic aldehyde, hydroxylamine hydrochloride, and ethyl acetoacetate under a solvent free condition at 80 °C is described. This protocol has promising features for the reaction response such as shorter reaction time, easy work-up, ease of separation of pure product with high yields and simplicity in the experimental procedure. The products have been obtained in high yields (80–90%) and convenient reaction time (15–30 min). The method is operationally simple and eco-friendly. 相似文献
