Estimating hydrogen production potential in biorefineries using microbial electrolysis cell technology

Future biofuel and bioproducts industries are expected to generate significant volumes of waste streams containing easily degradable organic matter. The emerging MEC technology has potential to derive added-value from these waste streams via production of hydrogen. A methodology to determine hydrogen production potential from wastewaters is reported. Biorefinery process streams, particularly the stillage or distillation bottoms contain underutilized sugars as well as fermentation and pretreatment byproducts, in the case of lignocellulosic biorefineries. Estimates of hydrogen production from existing starch-based biorefineries indicate potential to generate 750-8900 m³/hr of hydrogen. In a lignocellulosic biorefinery designed to produce 265,000 m³ of ethanol per year, it is estimated that 1260-7200 m³/hr of hydrogen can be generated. Removal of fermentation and pretreatment byproducts from stillage streams has the added potential to enable water recycle.     

浮法玻璃生产中富氧燃烧技术在煤气发生炉上的应用

浮法玻璃生产行业是高耗能行业，且当前多数浮法玻璃生产企业制氮均使用小型空分机组，存在着大量富氧气体放空现象，在当前提倡低碳经济环境下，实现富氧气体的回收利用将是浮法玻璃生产节能降耗的一条有效途径。     

The Inhibition of Ozone Generation at Ni/Sb-SnO2 Electrodes in High Concentrations of Dissolved O3

The work reported in this paper investigated the observation that high concentrations of ozone in the electrolyte inhibits the electrochemical ozone evolution process at Ni/Sb-SnO₂ anodes in aqueous sulfuric acid. We show that inhibition does indeed take place and that this inhibition does not affect the current density and hence appears to reflect an increase in the ratio of O₂ to O₃ evolved. A possible mechanism for the inhibition is proposed. It was found that Celgard 2400 membrane was an acceptable alternative to Nafion in the divided electrolysis cell employed.     

Design and preparation of a novel degradable low-temperature co-fired ceramic (LTCC) composites

New degradable low-temperature co-fired ceramic (LTCC) composites consisting of AlN ceramic and low-melting composition B₂O₃-2SiO₂ have been fabricated at sintering temperature of 850?°C. Boron exists in low-melting composition B₂O₃-2SiO₂ in the form of [BO₃] triangle, which can not form a uniform network structure with [SiO₄] tetrahedron, this cause relatively lower chemical stability, further leading to the reaction of amorphous phase with water, therefor, the material can disintegrate when exposed to water, while Ag as electrode can be easily separated and recycled with gentle agitation and centrifugation. This has a certain significance in reducing soil pollution and water pollution caused by the landfill of LTCC products. and also in reducing the recycling costs. When AlN content is 40?wt%, samples sintered at 850?°C have thermal conductivity of 1.632?W/(m?K), dielectric constant of 4.93, dielectric loss of 0.0064, and flexural strength of 60.26?MPa, results indicate that samples are potential for LTCC application.     

生物柴油在柴油机中的应用研究

本文简要介绍了生物柴油在国内外发展现状,并以正和生物柴油为燃料,以4102QBZ增压柴油机为研究对象,进行了纯生物柴油和生物柴油与柴油的混合燃料在柴油机中应用的试验研究。试验结果表明：在柴油机不进行任何调整的情况下,燃用生物柴油能保证柴油机的动力性不变,并明显降低柴油机微粒、烟度、HC和CO排放,是一种理想的替代燃料。
