Synthesis and Characterization of Ru/Al2O3 Nanocatalyst for Ammonia Synthesis
Ru/Al2O3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of RuCl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. The samples were characterized by TEM, XRD and TPR techniques. The catalytic performance tests were carried out in a fixed-bed micro-reactor under diffe...
متن کاملThe relation of ammonia concentration to urea synthesis.
We suggest in Fig. 5 that arginase is common to the two cycles. Although the remaining steps of the two cycles are shown separately in this figure, there seems to be no objection to the assumption that the enzymes catalysing the remaining steps are common to the two cycles, provided that in physiological conditions these enzymes, as is the case with arginase, are likely to be far from the point...
متن کاملGeneration of ammonia from non-urea sources in a faecal incubation system.
1. A 25% faecal suspension in sodium chloride solution, incubated anaerobically at 37 degrees C for 48 h, showed excellent survival of all the main groups of faecal bacteria. 2. All faecal incubation systems studied generated large amounts of ammonia, particularly those in which bacterial counts fell during incubation. As normal faeces contain negligible amounts of urea this ammonia must have b...

متن کاملModified reagents for determination of urea and ammonia.
This reduces the number of reagents required for color development to two, each of which is stable for 60 days or more if kept cool and in amber bottles protected from light. These reagents are added in equal volumes to the ammonia sample. For example, to 1-5 g. of ammonia in a volume of 1 ml. or less, 5 ml. each of diluted solutions 1 and 2 are added successively. Maximum blue color is produce...
