Production of biohydrogen from brewery wastewater using Klebsiella pneumoniae isolated from the environment

The use of wastewater for the biological production of H₂ (biohydrogen) by dark fermentation has been studied for a variety of waste substrates and mixed or isolated inocula. However, for brewery wastewater (BW), which is generated in large volumes and has characteristics that are highly suitable for acidogenic fermentation, the available studies describe the use of mixed cultures, especially pretreated methanogenic inocula. The aim of this work was to isolate an enterobacterium from aviary litter that was capable of fermenting BW and generating biogas rich in H₂. The biochemical characterization and species confirmation confirmation revealed the isolation of Klebsiella peneumoniae, which provided efficient production of biogas rich in H₂ (30–40%) in batch assays performed for up to 72 h, with the inoculum in suspension, at a small scale (in serum bottles) and using a mechanically-stirred anaerobic reactor (AnBBR), employing crude BW without any supplementation. The hydrogen yield and molar hydrogen flow rate were 0.80–1.67 mol H₂ mol^?1 glucose and 0.2–2.2 mmol H₂ h^?1, respectively, indicating good performance of the inoculum in metabolizing this substrate and the possibility of optimizing the process by varying the duration of the batch.

建筑艺术形式应以本地文化为基石

建筑艺术既是物质的财富,又是精神的产品;它既是技术产物,又是艺术的创作。我们的先辈在当时营造了独具特色的生存空间,其建筑的亲和感、舒适性,留给后人多少赞叹!人类社会的发展已进入了现代工业社会,选择怎么样的建筑形式,采取怎么样的文化模式是应该摆在我们面前的问题。     

海派文化视域下的纤维壁挂设计实践

为给纤维壁挂设计实践提供参考,通过分析海派文化特质,从海派建筑、海派图样、海派旗袍、海派京剧中分别提取石库门、文字、旗袍盘扣、脸谱等设计元素进行纤维壁挂花型图案设计,运用不完全提花、空气层提花及芝麻点翻针衬纬提花等组织设计壁挂组织结构,制作纤维壁挂编织花型小样图与花型制版工艺,并用电脑横机编织纤维壁挂实样以展示和分析设计效果。设计实践结果表明,将海派文化融入纤维壁挂设计,丰富了纤维壁挂的设计元素与肌理效应,是一种纤维壁挂创新设计方法,在传承海派文化的同时也为纤维壁挂设计带来新思路。     

Oxidative steam reforming of ethanol over Ru–Al2O3 catalyst in a dense Pd–Ag membrane reactor to produce hydrogen for PEM fuel cells

This study focuses on the influence of oxygen addition on ethanol steam reforming (ESR) reaction performed in a dense Pd–Ag membrane reactor (MR) for producing hydrogen directly available for feeding a polymer electrolyte membrane fuel cell (PEMFC). In particular, oxygen addition can prevent ethylene and ethane formation caused by dehydration of ethanol as well as carbon deposition. The MR is operated at 400 °C, H₂O:C₂H₅OH = 11:1 as feed molar ratio and space velocity (GHSV) ∼2000 h⁻¹. A commercial Ru-based catalyst was packed into the MR and a nitrogen stream of 8.4 × 10⁻² mol/h as sweep gas was flowed into the permeate side of the reactor. Both oxidative ethanol steam reforming (OESR) and ESR performances of the Pd–Ag MR were analyzed in terms of ethanol conversion to gas, hydrogen yield, gas selectivity and CO-free hydrogen recovery by varying O₂:C₂H₅OH feed molar ratio and reaction pressure. Moreover, the experimental results of the OESR and ESR reactions carried out in the same Pd–Ag MR are compared in order to point out the benefits due to the oxygen addition. Experimentally, this work points out that, overcoming O₂:C₂H₅OH = 1.3:1, ethanol conversion is lowered with a consequent drops of both hydrogen yield and hydrogen recovery. Vice versa, a complete ethanol conversion is achieved at 2.5 bar and O₂:C₂H₅OH = 1.3:1, whereas the maximum CO-free hydrogen recovery (∼30%) is obtained at O₂:C₂H₅OH = 0.6:1.
