Process for recovering low-boiling acids
(United States. Patent and Trademark Office, 2002-05-28)
The invention provides a method for recovering low-boiling acids from a concentrated solution of the calcium salt of the acid by treating the concentrated solution of calcium salts of the low-boiling acids with a high ...
Methods of biomass pretreatment
(United States. Patent and Trademark Office, 1999-02-02)
The invention is directed to methods for the pretreatment of a lignocellulose-containing biomass. Pretreatment comprises the addition of calcium hydroxide and water to the biomass to form a mixture, and subjecting the ...
Thermal conversion of volatile fatty acid salts to ketones
(United States. Patent and Trademark Office, 1999-10-19)
This invention provides a method for thermally converting volatile fatty acid (VFA) salts to ketones by mixing dry calcium salts of VFAs with hot heat transfer agent in an evacuated container, thereby causing thermal ...
Thermal conversion of fatty acid salts to ketones
(United States. Patent and Trademark Office, 2001-07-17)
This invention provides a method for thermally converting volatile fatty acid (VFA) salts to ketones by mixing dry calcium salts of VFAs with hot heat transfer agent in an evacuated container, thereby causing thermal ...
Recovery of fermentation salts from dilute aqueous solutions
(United States. Patent and Trademark Office, 2002-11-12)
Dilute solutions of fermentation sales may be concentrated by extracting water using low-miscibility, low-molecular-weight secondary and tertiary amines, e.g. triethylamine (TEA), diisopropyl amine (DIA), N,N-diethylmethylamine ...
Method for conversion of biomass to chemicals and fuels
(United States. Patent and Trademark Office, 2000-03-28)
This invention provides a method for thermally converting volatile fatty acid (VFA) salts to ketones by mixing dry calcium salts of VFAs with hot heat transfer agent in an evacuated container, thereby causing thermal ...
Calcium hydroxide pretreatment of biomass
(United States. Patent and Trademark Office, 1997-12-02)
Lignocellulose-containing materials are treated with lime (calcium hydroxide) and water at a relatively high temperature and for a certain period of time under certain conditions. The process variables were: lime loading ...
Recovery of fermentation salts from dilute aqueous solutions
(United States. Patent and Trademark Office, 1999-11-16)
Dilute solutions of fermentation sales may be concentrated by extracting water using low-miscibility, low-molecular-weight secondary and tertiary amines, e.g. triethylamine (TEA), diisopropyl amine (DIA), N,N-diethylmethylamine ...
