Abstract
A method of hydrogenation using a catalyst in the form of a plurality of porous particles wherein each particle is a support having nickel metal catalytic phase or reduced nickel deposited thereon in a first dispersed phase and an additional ruthenium metal deposited onto the support in a second dispersed phase. The additional ruthenium metal is effective in retarding or reducing agglomeration or sintering of the nickel metal catalytic phase thereby increasing the life time of the catalyst during hydrogenation reactions.
Claims26
A method for hydrogenation of an organic material in an aqueous phase into a product, comprising the steps of:
- providing a liquid reactant mixture containing liquid water and said organic material within a pressure reactor;
- adding a catalyst in the form of a plurality of particles, each particle formed of a porous support with an amount of a reduced nickel metal catalyst phase deposited upon the porous support in a first dispersed phase providing a catalyst activity, further having an added ruthenium metal upon the porous support as a second dispersed phase in an amount that is effective in resisting agglomeration or sintering of the nickel metal catalyst phase, wherein said second dispersed phase is separate and distinct from said first dispersed phase, and
- maintaining said liquid reactant mixture at temperature and pressure conditions from about 150.degree. C. to about 350.degree. C. and a hydrogen overpressure.
A catalyst for reacting an organic material in an aqueous phase, comprising:
- a particle formed of a porous support with an amount of a reduced nickel metal catalyst phase deposited upon the porous support in a first dispersed phase providing a catalyst activity, further having an added ruthenium metal upon the porous support as a second dispersed phase in an amount that is effective in resisting agglomeration or sintering of the nickel metal catalyst phase, wherein said second dispersed phase is separate and distinct from said first dispersed phase.
