Enhancement by SO2 of initial activity for selective catalytic reduction of NO with CH3OH over \gamma-alumina

The effect of SO₂ on catalytic activity for NO reduction to N₂ by methanol in excess oxygen over $\gamma$ -alumina has been investigated. SCR activity increased initially upon exposure of a fresh $\gamma$ -alumina catalyst to SO₂ which is attributed to formation of Brønsted acid sites. Longer exposure to SO₂ leads to a decline in catalytic activity to a lower steady-state NO_x reduction activity which is independent of the SO₂ content in the feed gas.     

Analysis of the Thermal Explosion in Systems Porous Reagent–Active Gas–Solid Product

The specific features of dynamics of the thermal explosion in systems porous reagent–active gas–solid product under conditions where the heattransfer and masstransfer regions are separated from the ambient medium are considered. In addition to the competition of heat release and heat removal, the process of initiation of exothermal chemical interaction in these systems under normal pressures depends significantly on conditions of filtration transport of the gaseous reagent. The induction and postinduction periods of the thermal explosion are studied. The theoretical analysis of thermalexplosion issues is supplemented by an experimental study of the process for the porous titanium–nitrogen–titanium nitride system.

Adhesion Mechanisms of Polyurethanes to Glass Surfaces I. Structure-Property Relationships in Polyurethanes and Their Effects on Adhesion to Glass

Polyurethanes were prepared from toluene diisocyanate (TDI), 1-4-butane diol (BDO) and polycaprolactone-based triols with varying molecular weights. Among each molecular weight triol-based urethane, hard segment content was varied from 20% to 70%. Differential scanning calorimetry, tensile testing, and Iosipescu shear testing were done on all the various urethanes prepared. Thermal characterization data revealed the dependence of phase separation on hard segment content as well as on the triol molecular weight. Tensile data and Iosipescu shear data further confirmed the observations made from the DSC data. The data further indicated that phase separation can greatly improve the modulus of cross-linked segmented urethanes. Adhesion of these urethanes to glass surface was evaluated using soda-lime float glass plate. Urethane samples were cast on the air side of the glass plates and adhesion was measured in shear mode. Adhesion data indicated that in addition to hard segment content, modulus, cross-link density, and molecular weight of the triols, phase separation seems to be a major factor in controlling adhesion. Surfaces of the failed adhesion samples were also analyzed and the failure mode was found to be cohesive, in varying degree, with the different urethane systems.

TGA－MS对煤燃烧时氯的析出特征的研究

ＴＧＡ－ＭＳ是研究煤在燃烧过程中氯及其它气体组分析出特征的有效方法。ＭＳ的结果表明，煤在燃烧时氯基本上是以ＨＣｌ的形式从煤中析出，其析出特征与煤中水分的析出有着密切关系，与ＣＯ２及ＳＯ２的析出也有一定的关系。英国煤和美国煤在燃烧时氯的析出特征基本相似，这也说明两国煤中氯的存在方式是相似的。ＭＳ谱图上的三个ＨＣｌ析出峰则说明至少有三种形式的氯存在于煤中。
