Abstract
An inexpensive, highly catalytic material preferably formed by a leaching process. The catalyst comprises a finely divided metal particulate and a support. The active material may be a nickel and/or nickel nickel alloy particulate having a particle size less than about 100 Angstroms. The support may be one or more metal oxides.
Claims66
A catalyst powder, comprising:
- a nickel or nickel alloy particulate having an average particle size of between about 10 and about 70 Angstroms, said particulate dispersed in a support matrix, said powder formed predominately of its nickel or nickel alloy particulate and support matrix.
A catalyst particle, comprising:
- a nickel and/or nickel alloy particulate having an average particle size of between about 10 and about 70 Angstroms, said particulate disposed in a support, said particulate and said support forming at least 25% by volume of said catalyst particle, said nickel alloy lacking platinum and palladium.
A catalyst, comprising:
- a metal particulate having an average particle size of between about 10 and about 70 Angstroms, said metal particulate comprising a nickel alloy, said nickel alloy lacking platinum and palladium, said nickel alloy comprising at least one element selected from the group consisting of Al, Co, Sn, Mn, Ti, and Fe;
- and
- a support.
