Benefits of technology

The patent text describes a method for binding or adhering particulate materials using a lignocellulosic syrup. The syrup can be applied to the material and then brought into contact with another surface to adhere them together. The technical effect of this method is that it provides a simple and effective way to bind materials together, which can be useful in various applications.

Problems solved by technology

Binders and adhesives are useful in many applications particularly where materials with desired properties are difficult to handle due to their particulate nature.

Embodiment Construction

[0013]The following definitions and abbreviations are to be used for the interpretation of the claims and the specification.

[0014]As used herein, the terms “comprises,”“comprising,”“includes,”“including,”“has,”“having,”“contains” or “containing,” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a composition, a mixture, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, mixture, process, method, article, or apparatus.

[0015]Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

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.

Description

[0001]This application claims the benefit of U.S. Provisional Applications 61 / 889061, filed Oct. 10, 2013 and 62 / 000639, filed May 20, 2014 each of which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The invention relates to the field of materials comprising a binder or adhesive. More specifically, syrup that is a co-product of a lignocellulosic biomass fermentation process is effectively used as a binder or adhesive.BACKGROUND OF THE INVENTION[0003]Binders and adhesives are useful in many applications particularly where materials with desired properties are difficult to handle due to their particulate nature. Substances that have been used as binders, for example with coal fines, include starch and molasses (U.S. Pat. No. 5,009,671), asphaltic binder material (U.S. Pat. No. 823,025), bitumen binders (U.S. Pat. No. 3,966,427), or liquefied biomass (U.S. Pat. No. 5,916,826). Additionally lignosulfonate, a waste liquor of the sulfate pulping process o...
