Abstract

Catalysts and composite materials comprised of catalytically active materials intercalated with alkali metals and/or optionally coated on alkali metals or combinations of alkali and alkali earth metals are disclosed. Also disclosed are methods for enhancing reactions between hydrogen and organic materials by reacting said catalysts with solvents where such reactions generate a portion of the hydrogen and heat necessary to cause the desired reaction between an organic material and hydrogen and also act to fracture said catalytically active material into higher surface area particles with enhanced catalytic ability. Said catalysts may be dispersed in immiscible aprotic solvents to enhance transportation and safety considerations prior to use.

Claims

1. A catalyst of the form MX. Where;

M is an intercalation host, and

X is an intercalate alkali metal.

2. The catalyst of claim 1 where M is a chalcogenide.

3. The catalyst of claim 1 where M is a transition metal dichalcogenide.

4. The catalyst of claim 1 where M is MoS₂ or WS₂.

5. The catalyst of claim 1 where X is lithium.

6. A dispersion of the catalyst of claim 1 in a liquid hydrocarbon.

15. A process for hydrogenating an organic material. Said process being comprised of the following steps;

a) mixing a slurry or liquid form of the said organic material with the catalyst of claim 1, and water, for sufficient time and in a manner such that the water reacts with the X component of the catalyst, to produce both heat and hydrogen while simultaneously fracturing the M component of the said catalyst and thereby exposing catalytically active sites on said M component to enhance the hydrogenation of said organic material.

7. A composite of the form MXY. Where;

M is an intercalation host

X is an intercalate alkali metal

Y is an material selected from the Group IA-alkali metals, alkali metal hydrides, Group IIA-alkali earth metals, alkali earth metal hydrides, Group IIIA-metals, metal hydrides, and alloys, combinations, or mixtures of said materials.

8. The composite of claim 7 where M is a chalcogenide.

9. The composite of claim 7 where M is a transition metal dichalcogenide.

10. The composite of claim 7 where M is MoS₂ or WS₂.

11. The composite of claim 7 where X is lithium.

12. The composite of claim 7 where Y is sodium

13. The composite of claim 7 where the size of particles of Y are in the range of 1 to 100 microns.

14. A dispersion of the composite of claim 7 in a liquid hydrocarbon.

16. A process for hydrogenating an organic material. Said process being comprised of the following steps;

a) mixing a slurry or liquid form of the said organic material with the composite of claim 7, and water, for sufficient time and in a manner such that the water reacts with the XY components of the composite, to produce both heat and hydrogen while simultaneously fracturing the M component of the said composite and thereby exposing catalytically active sites on said M component to enhance the hydrogenation of said organic material.
