  • Publication number: 20200148835
    Abstract: The present relates to a process for the depolymerization of lignin using chemicals recoverable by the soda or kraft mill recovery cycles. The process involves the use of sodium hydroxide or white liquor to depolymerize lignin in black liquor or other lignins (e.g. hydrolysis lignin, kraft lignin) by conducting the reaction at 170-250° C. for up to 3 hours in the presence or absence of a co-solvent and a capping agent. The depolymerized lignin is then obtained by acidifying the reaction products to a low pH to precipitate the de-polymerized lignin, followed by particle coagulation, cake filtration and washing with acid and water to obtain a purified depolymerized lignin product.

  • Patent number: 10023466
    Abstract: A composition and a method for producing mesoporous carbon materials with a chiral or achiral organization. In the method, a polymerizable inorganic monomer is reacted in the presence of nanocrystalline cellulose to give a material of inorganic solid with cellulose nanocrystallites organized in a chiral nematic organization. The cellulose can be carbonized through thermal treatment under inert atmosphere (e.g., nitrogen or argon) and the silica may subsequently be removed using aqueous solutions of sodium hydroxide (NaOH) or hydrogen fluoride (HF) to give the stable mesoporous carbon materials that retain the chiral nematic structure of the cellulose. These materials may be obtained as free-standing films with very high surface area. Through control of the reaction conditions the pore-size distribution may be varied from predominantly microporous to predominantly mesoporous materials.

  • Patent number: 9945000
    Abstract: Acid hydrolysis of biomass is an important step for releasing the component sugars before converting them to fuels and/or biochemicals. During such a process, a significant amount of mineral acid, such as sulfuric acid, is used. In most cases, the residual acid is neutralized with lime before the sugar conversion step. By doing so, a waste calcium sulphate stream is generated and sent to disposal. The efficient separation of acid from the sugars would allow the recycle of the acid and make the entire process more economically viable. We found that a resin bed packed with an acid retardation resin can be used to achieve an efficient separation (i.e. 98.5% recovery of the acid) of the sulfuric acid from the sugars. The resin bed can be simply regenerated with water.
