Abstract
A composition that is useful in land surface applications is produced from ash resulting from burning at least one of lignocellulosic filter cake and lignocellulosic syrup co-products of a lignocellulosic biomass fermentation process for production of ethanol. The composition can be applied to surfaces such as fields, roads, and landfills as a stabilizer and/or fertilizer. Burning of material to produce the ash provides thermal energy.
Claims26
A composition comprising ash produced by burning lignocellulosic filter cake and optionally lignocellulosic syrup wherein the filter cake and syrup are co-products of a process for the production of alcohol from a lignocellulosic biomass.
A process for producing energy and a land application composition comprising:
- f) providing a lignocellulosic filter cake that is a co-product of a process for the production of alcohol from a lignocellulosic biomass;
- g) optionally providing a lignocellulosic syrup that is a co-product of a process for the production of alcohol from a lignocellulosic biomass;
- h) providing at least one combustion enhancement material;
- i) adding the filter cake of (a), optionally the syrup of (b), and the combustion enhancement material of (c) to a vessel;
- and
- j) combusting the contents of the vessel;
- wherein energy and a lignocellulosic ash are produced;
- and
- wherein the lignocellulosic ash is a land application composition.
