Many commercial processes are available for the removal of H2S from gaseous streams. The desulfurization of gas streams using aqueous ferric sulfate solution as washing liquor is studied. Apart from sulfur, only H2O is generated in the process, and consequently, no waste treatment facilities are required. A distinct advantage of the process is that the reaction of H2S with is so rapid and compl...

Conventional kinetic analysis of the reactions of nitromethane (NM), nitroethane (NE) and 2-nitropropane (2-NP) with hydroxide ion in water revealed that the reactions are complex and involve kinetically significant intermediates. Kinetic experiments at the isosbestic points where changes in reactant and product absorbance cancel indicate the evolution and decay of absorbance characteristic of ...

Abstract The high use of aluminium foil in food and beverage packaging has caused solid waste to increase rapidly, so treatment is required. This study investigates the best concentration reactant recovery from as potash alum coagulant. Potassium hydroxide used for dissolved aluminium, sulphuric acid added form crystals. experimental result got a maximum point synthesis foil: potassium 3 M dan ...

Several test compounds were introduced into a unidirectional flow Ion mobillty spectrometer by both gas chromatography (GC) and supercritical fluld chromatography (SFC). The test samples were drugs from three general classes, opiates, benrodiazoplnones, and steroids. Drm spectra were collected for each compound by Fourier transform ion moblllty spectrometry. The drlft veioclty data for each com...

The dynamic behavior for a high-purity/high-conversion reactive distillation is investigated. The impact of disturbance magnitudes and directions on both open loop and closed loop stability of the system is studied. Excess of less volatile reactant in two-reactant-two-product generic reactive distillation is found to enhance open loop stability, but decreases the products purity. However, exces...

Individuals nonconsciously and unintentionally pursue goals they associate with relationship partners (Fitzsimons & Bargh, 2003; Shah, 2003). Here, we demonstrate conditions under which individuals nonconsciously and unintentionally reject goals they associate with relationship partners and instead pursue opposing goals. In Experiment 1, participants were subliminally primed with the name of a ...

We consider catalytic branching populations. They consist of a catalyst population evolving according to a critical binary branching process in continuous time with a constant branching rate and a reactant population with a branching rate proportional to the number of catalyst individuals alive. The reactant forms a process in random medium. We describe asymptotically the genealogy of catalytic...

The KEGG RPAIR database is a collection of biochemical structure transformation patterns, called RDM patterns, and chemical structure alignments of substrate-product pairs (reactant pairs) in all known enzyme-catalyzed reactions taken from the Enzyme Nomenclature and the KEGG PATHWAY database. Here, we present PathPred (http://www.genome.jp/tools/pathpred/), a web-based server to predict plausi...
