摘要:
This invention relates to the field of heterogeneous catalysis, and more particularly to catalysts including carbon supports having formed thereon compositions which comprise a transition metal in combination with nitrogen and/or carbon. The invention further relates to the fields of catalytic oxidation, including the preparation of secondary amines by the catalytic oxidation of tertiary amines.

This invention relates to the field of heterogeneous catalysis, and more particularly to catalysts including carbon supports having formed thereon compositions which comprise a transition metal in combination with nitrogen and/or carbon. The invention further relates to the fields of catalytic oxidation and dehydrogenation reactions, including the preparation of secondary amines by the catalytic oxidation of tertiary amines and the preparation of carboxylic acids by the catalytic dehydrogenation of alcohols.
摘要:
An oxidation catalyst is prepared by pyrolyzing a source of iron and a source of nitrogen on a carbon support. Preferably, a noble metal is deposited over the modified support which comprises iron and nitrogen bound to the carbon support. The catalyst is effective for oxidation reactions such as the oxidative cleavage of tertiary amines to produce secondary amines, especially the oxidation of N-(phosphonomethyl)iminodiacetic acid to N-(phosphonomethyl)-glycine.
摘要:
A short message gateway comprises a gateway function (SMGF) and programs in an HLR or a home network (IMT-2000). It does not have any physical impact on a foreign (PDC) network, and it converts short messages communicated between the home and foreign networks. The gateway function (SMGF) primarily inter-operates with an HLR and an SMSC of the home network, the GMSC providing the link to the foreign network. The gateway allows communication in a wide variety of scenarios for communication with subscribers in the home and foreign networks and roaming subscribers from one to the other.
