Abstract

Lignocellulosic syrup is produced as a co-product in a lignocellulosic biomass fermentation process, such as one producing ethanol from lignocellulosic biomass. The lignocellulosic syrup may be used as a binder of particulate materials. In addition, the syrup may be used as an adhesive.

Claims

1. A method for binding a particulate material comprising:

a) providing a lignocellulosic syrup;

b) providing at least one particulate material contacting the particulate material of (b) with the syrup of (a);

wherein the syrup binds the particulate material.

2. The method of claim 1 wherein the contacting of (c) is mixing the syrup of (a) with the particulate material of (b).

3. The method of claim 2 wherein the particulate material is selected from the group consisting of animal feed ingredients, carbon black, and fly ash.

4. The method of claim 1 wherein the contacting of (c) is applying the syrup of (a) to the particulate material of (b).

5. The method of claim 4 wherein the particulate material of (b) covers a path, road, nursery, orchard, or construction area.

8. The method of claim 1 or 6 wherein the lignocellulosic syrup is a co-product of a process for the production of alcohol from a lignocellulosic biomass.

9. The method of claim 8 wherein the lignocellulosic biomass is selected from the group consisting of corn cobs, corn stover, grasses, wheat straw, barley straw, hay, rice straw, switchgrass, waste paper, sugar cane bagasse, sorghum plant material, soybean plant material, woody plants, vegetables, fruits, and flowers.

10. The method of claim 1 or 6 wherein the lignocellulosic syrup is a co-product of a process that employs ammonia for the pretreatment of a lignocellulosic biomass.

11. The method of claim 10 wherein the lignocellulosic syrup comprises:

a) from about 40% to about 70% solids;

b) from about 10 g/l to about 30 g/l of acetamide; and

c) at least about 40 g/l of sugars;

wherein the cellulosic syrup has a density of about 1 to about 2 g/cm³ and a viscosity of less than 500 SSU at 100°

F. (38°

C.).

6. A method for adhering two surfaces comprising:

a) applying to at least one surface a composition comprising a lignocellulosic syrup; and

b) bringing the two surfaces into contact with each other such that the lignocellulosic syrup is interposed between the two surfaces.

7. The method of claim 6 wherein the composition is selected from cement, and rewettable gum tape.

12. A composition comprising lignocellulosic syrup and at least one additional particulate material.

13. The composition of claim 12 wherein the lignocellulosic syrup is a co-product of a process for the production of alcohol from a lignocellulosic biomass.

14. The composition of claim 13 wherein the lignocellulosic biomass is selected from the group consisting of corn cobs, corn stover, grasses, wheat straw, barley straw, hay, rice straw, switchgrass, waste paper, sugar cane bagasse, sorghum plant material, soybean plant material, woody plants, vegetables, fruits, flowers, empty palm fruit bunch, and energy cane.

15. The composition of claim 12 wherein the lignocellulosic syrup is a co-product of a process that employs ammonia for the pretreatment of a lignocellulosic biomass.

16. The composition of claim 15 wherein the syrup comprises:

a) from about 40% to about 70% solids;

b) from about 10 g/l to about 30 g/l of acetamide; and

c) at least about 40 g/l of sugars;

wherein the cellulosic syrup has a density of about 1 to about 2 g/cm³ and a viscosity of less than 500 SSU at 100 °

F. (38°
