Abstract

Liquid suspensions are disclosed comprising a suspending medium, small particles of biomass, and small particles of an inorganic material. The inorganic material stabilizes the suspension, so that it may be transported by pipeline or tank car without developing a sediment.

The suspension may be used in manufacturing a bio-fuel.

Claims

1. A process for converting biomass to reaction products, the process comprising:

(a) contacting biomass particles with an inorganic material having catalytic properties, the inorganic material including;

     1) a zeolite, and

     2) at least one of a sepiolite or saponite; and

(b) converting the biomass particles to reaction products in the presence of the inorganic material,

wherein said biomass particles comprises cellulose or lignocellulose.

2. The process of claim 1, wherein the inorganic material includes a sepiolite.

3. The process of claim 1, wherein the inorganic material includes saponite.

4. The process of claim 1, wherein the inorganic material includes a sepiolite and a zeolite.

5. The process of claim 1, wherein the inorganic material includes saponite and a zeolite.

6. The process of claim 1, wherein step (a) further includes mixing the biomass particles and the inorganic material in a liquid suspension medium.

7. The process of claim 6, wherein the liquid suspension medium includes water.

8. The process of claim 1, wherein step (b) further includes converting the biomass particles to reaction products via at least one process chosen from gasification, steam reforming, thermal cracking, coking, catalytic cracking, hydro-cracking, and hydro-processing.

9. The process of claim 1, wherein step (b) further includes converting the biomass particles to reaction products via a fluid catalytic cracking (FCC) process.

10. The process of claim 1, wherein the biomass particles includes cellulose and lignocellulose.

11. The process of claim 1, wherein the biomass particles includes cellulose.

12. The process of claim 1, wherein the biomass particles includes lignocellulose.

13. The process of claim 1, wherein the reaction products include liquid reaction products or gaseous reaction products.

14. The process of claim 1, wherein the reaction products comprise liquid reaction products and gaseous reaction products.

15. A process for converting biomass to reaction products, said process comprising the steps of:

(a) contacting biomass particles with an inorganic material having catalytic properties, the inorganic material comprising;

     1) a zeolite, and

     2) a sepiolite; and

(b) converting said biomass particles to reaction products in the presence of said inorganic material.

16. The process according to claim 15, wherein said biomass particles comprises cellulose or lignocellulose, or a combination thereof.

17. The process according to claim 15, wherein said biomass particles comprises lignocellulose.

18. The process according to claim 15, wherein the converting of step (b) comprises converting said biomass particles to reaction products via a fluid catalytic cracking (FCC) process.

19. A process for converting biomass to reaction products, said process comprising the steps of:

(a) providing a stable liquid composition, said stable liquid composition comprising a liquid suspension medium having suspended therein;

     1) biomass particles, said biomass particles comprising cellulose or lignocellulose, or a combination thereof; and

     2) an inorganic material having catalytic properties, said inorganic material comprising;

i) a zeolite, and ii) at least one of a sepiolite or saponite; and

(b) converting said biomass particles to reaction products in the presence of said inorganic material,

wherein at least a portion of said inorganic material prevents hydrogen bond formation between at least a portion of said biomass particles to thereby prevent at least a portion of said biomass particles from solidifying in said stable liquid composition.

20. The process according to claim 19, wherein at least a portion of said inorganic material is coated onto at least a portion of said biomass particles.

21. The process according to claim 19, wherein the converting in step (b) comprises converting said biomass particles into reaction products via a fluid catalytic cracking (FCC) process.

22. The process according to claim 21, further comprising feeding said liquid composition into a low cracking activity zone of an FCC unit, wherein said low cracking activity zone comprises a stripper or a regenerator.

23. The process according to claim 19, wherein said liquid suspension medium comprises water.

24. The process according to claim 19, wherein said inorganic material comprises saponite.

25. The process according to claim 19, wherein said inorganic material comprises a sepiolite.
