SYNERGIC PROMOTION OF CATALYST BY GROUP VIII B ELEMENTS
Group VIII B metal oxides supported on gamma-alumina were investigated as catalysts and promoters of MoO3 hydrodesulfurization catalysis. Superior promotion was observed in PbO promoted catalyst compared to that of CoO, the typically accepted promoter. Other metal oxides, SnO and Ho2O3 exhibited reasonable hydrodesulfurization catalysis promotion but lower than for CoO promoted catalyst.
متن کاملIntersection cohomology of B ×B-orbit closures in group compactifications
An adjoint semi-simple group G has a “wonderful” compactification X, which is a smooth projective variety, containing G as an open subvariety. X is acted upon by G×G and, B denoting a Borel subgroup of G, the group B × B has finitely many orbits in X. The main results of this paper concern the intersection cohomology of the closures of the B × B-orbits. Examples of such closures are the “large ...
متن کاملOn the origin of the unusual orbit of Comet 2P/Encke
The orbit of Comet 2P/Encke is difficult to understand because it is decoupled from Jupiter—its aphelion distance is only 4.1 AU. We present a series of orbital integrations designed to determine whether the orbit of Comet 2P/Encke can simply be the result of gravitational interactions between Jupiter-family comets and the terrestrial planets. To accomplish this, we integrated the orbits of a l...
متن کاملA polarization study of comet Hyakutake ( C / 1996 B 2 )
Observations for the linear polarization of comet Hyakutake (C/1996B2) are carriedout at three continuumwavebands: 3650Å, 4845Å and 6840Å. These observations were taken on March 13 and March 18, 1996 when the phase angles were 38.1 and 36.9, respectively. These results indicate an increase in the degree of polarizationwith phase angle andwavelength, in general. Present results show that comet H...
