Abstract

A slurry suspension is provided, which comprises (a) carbonaceous material particles having an average diameter D 50 comprised between 0.1 μm and 200 μm; (b) an organic compound comprising at least one amine group; and (c) an organic phase.

First claim

The invention claimed is:

1. A slurry suspension comprising:
(a) carbonaceous material particles having an average diameter D 50 from 0.1 μm to 200 μm;
(b) an organic compound comprising at least one amine group, wherein the organic compound comprising at least one amine group is an amine of formula (V):
H 2 N—R1—NH 2   (V)

 wherein R1 represents a saturated or unsaturated, linear, branched or cyclic, aliphatic or aromatic hydrocarbon chain of C 2 -C 22 ; and
(c) an organic phase.

2. The suspension according to claim 1 wherein said suspension further comprises (d) a viscosity controlling agent.

3. The suspension according to claim 1 wherein said carbonaceous material particles are selected from a group consisting of a vegetal biomass, a coal, a coke, a graphite, a char, a biocoal and a mix thereof.

4. The suspension according to claim 3 wherein the vegetal biomass is a torrefied vegetal biomass.

5. The suspension according to claim 1 wherein the carbonaceous material particles provide the size distribution as follows:
D 10 from 1 to 50 μm, and
D 90 from 50 to 500 μm.

6. The suspension according to claim 1 wherein the carbonaceous material particles represent from 25% to 50% by weight of the total weight of the suspension.

7. The suspension according to claim 1 wherein the organic compound comprising at least one amine group is ethylene diamine.

8. The suspension according to claim 1 wherein the organic compound comprising at least one amine group represents from 0.1% to 5% by weight of the total weight of the suspension.

9. The suspension according to claim 1 wherein the organic phase is selected from a group consisting of a fossil-based liquid and a derivative thereof, a biomass-based liquid and a derivative thereof, and a mix thereof.

10. The suspension according to claim 9 wherein the fossil-based liquid is a petroleum-based liquid or a derivative thereof.

11. The suspension according to claim 1 wherein the organic phase represents from 50% to 75% by weight of the total weight of the suspension.

12. The suspension according to claim 2 wherein the viscosity controlling agent is selected from a group consisting of clay powder, clay gel, a hydrogenated castor oil, carbon black and a mix thereof.

13. A method for the preparation of a slurry suspension according to claim 1 , the method comprising at least the mixing of:
(a) carbonaceous material particles having an average diameter D 50 from 0.1 μm to 200 μm;
(b) an organic compound comprising at least one amine group, wherein the organic compound comprising at least one amine group is an amine of formula (V):
H 2 N—R1—NH 2   (V)

 wherein R1 represents a saturated or unsaturated, linear, branched or cyclic, aliphatic or aromatic hydrocarbon chain of C 2 -C 22 ; and
(c) an organic phase, and optionally
(d) a viscosity controlling agent.

14. A method for generating power, the method comprising combustion of the slurry suspension according to claim 1 .

15. A method for providing a stable and redispersible slurry suspension comprising carbonaceous material particles having an average diameter D 50 from 0.1 μm to 200 μm, the method comprising using an organic compound comprising at least one amine group and optionally a viscosity controlling agent.

16. The suspension according to claim 4 wherein the vegetal biomass is torrefied wood particles.

17. The suspension according to claim 3 , wherein said carbonaceous material particles are biocoal.

18. The suspension according to claim 3 , wherein said carbonaceous material particles are coal.

19. The suspension according to claim 18 , wherein the coal is selected from a group consisting of anthracite, semi-anthracite, charcoal, solvent refined coal, medium and high-volatile bituminous, sub-bituminous and lignite coals.
