氢氧化钡、氯化锌等产品的生产工艺改进

针对生产氯化钡、硫氢化钠等产品的化工厂的困境，在不做大量投资、不做大的改动、不改变原厂的基础上，提出了改善产品结构、革新生产工艺的方法。原有生产状况是：利用原料硫化钡、盐酸、硫化钠生产氯化钡和硫氢化钠，但氯化钡亏损，整体效益差。改进新工艺为：在原有原料中增加氧化锌，即以粗质氧化锌、硫化钡、盐酸、硫化钠为原料生产氢氧化钡、氯化锌、硫氢化钠，以效益好的氢氧化钡、氯化锌取代了氯化钡，并保存了原来效益好的硫氢化钠，整体效益大大提高。

Properties of rubbery polymers for the recovery of hydrogen sulfide from gasification gases

Polydimethyl siloxane (PDMS) and two polyether‐polyamide copolymers (trade name Pebax) were evaluated for their ability to transport and separate gasification gases. Specifically, the permeabilities of hydrogen, carbon monoxide, carbon dioxide, and hydrogen sulfide were evaluated at temperatures up to 200°C. The permeabilities of all gases were approximately ten times faster through the PDMS than the Pebax materials. The permeabilities through all materials at all temperatures evaluated were H₂S > CO₂ > H₂ > CO. As the temperature increased, the permeabilities of all gases increased through the Pebax. Conversely, for PDMS, hydrogen and carbon monoxide permeabilites increased with temperature while those of H₂S and CO₂ decreased. The H₂S/H₂ selectivities ranges from 1.2 (PDMS at 200°C) to 10.3 (Pebax 2533 at 35°C). The activation energies for permeation of these polymer/penetrant pairs are reported. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 85: 2436–2444, 2002     

H2S低电耗电解制H2新方法

A new technique of lower electricity consumption electrolysis producing H2 has been developed, and the factors affecting producing H2 production were investigated. The results found that under the same electrolysis conditions, H2 production on the cathode increased with increasing electrolyte solution alkalinity; but decreased with increasing zinc ion concentration in the electrolyte solution. The results also revealed that H2 production on the cathode fluctuated with increasing electrolysis voltage, and reached a maximum when the voltage was at 0. 6 V. In a certainty range, it would be favorable to reduce the electricity consumption in H2 production with increasing electrolyte solution alkalinity; but the electricity consumption would be increase when electrolysis voltage was higher. Compared with producing H2 from H2O, the electrolysis voltage was lower by about IV, and the electricity consumption of H2 also decreased by 50% .     

生物滤池去除污水处理厂臭气的应用研究

研制了一套生物过滤系统,用于处理污水处理厂生化水解池所排放的臭气。以某污水处理厂的生物滤池为研究对象,经过调试使用后,在进口段气体中H2S、NH3的质量浓度分别小于7.0、90.0 mg/m3时,其去除率分别达到90%和99%左右。并通过试验分析了运行时间、进气浓度、填料含水率、温度对除臭效率的影响。     

兴安落叶松硫化钠预处理的研究

以１００％和８０％两种硫化度的药液在相同硫化钠浓度、１５５℃下预处理兴安落叶松木片，研究了疏化度及预处理时间对预处理液硫化钠浓度、落叶松主要化学组成及木片中硫含量的影响．结果表明，在较高温度下处理落叶松，药液硫化钠浓度、木材化学组成及木片中硫含量的变化主要发生在预处理的前１小时；８０％硫化度的预处理液中由于存在一定量的氢氧化钠，对得率、木素脱除、抽提物溶出及碳水化合物的降解作用较为强烈；预处理液中硫化钠的消牦仅与初始硫化钠浓度有关，而与硫化度无关，较高的硫化度有利于木片中木素的硫化．
