    Abstract: Most processes currently being proposed and/or used for the production of lignin from kraft or soda black liquors are capable of producing two main types of lignin: high residual content (HRC) lignin and low residual content (LRC) lignin. Surprisingly, it was discovered that HRC lignin, is a suitable ingredient in alkaline adhesives, particularly wood adhesives of the phenolic type (e.g. resole resins). This biomaterial is environmentally green and remarkably low cost, which makes it an industrially viable material to be used as a novel and major ingredient in phenolic adhesives for the manufacture of exterior grade plywood, laminated veneer lumber, oriented strand board (OSB) and other wood products - this was successfully demonstrated in a number of laboratory experiments as well as several different mill trials. The composition, preparation and application of such wood adhesives are hereby disclosed.

    Abstract: A process for chlorine dioxide production uses waste glycerol from biodiesel plants as a reducing agent. This untreated waste stream may contain other reducing agents such as sodium chloride and methanol which were found to enhance the chlorine dioxide production. Other chemicals present in this waste stream did not affect the operation of the chlorine dioxide generator. Substituting the waste glycerol for methanol or other reducing agents helps kraft pulp mills in reducing the cost of producing chlorine dioxide while providing a use for the untreated waste glycerol stream.

    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.

    Abstract: The present invention relates to a method of producing furfural and extracting lignin from a hemi-cellulosic biomass solution comprising a total quantity of C5 sugars, comprising the steps of heating the hemi-cellulosic biomass solution to a temperature of at least about 200°C; acidifying the hemi-cellulosic biomass solution with acid to produce the furfural in vapor phase; and condensing the furfural to recover furfural in solution, wherein the furfural is produced at a total molar yield of at least 70% of moles of furfural produced/the total moles C5 sugars present in the initial hemi-cellulosic biomass solution. Low molecular weight lignin can also be recovered from the hemi-cellulosic biomass solution prior to furfural production by membrane concentration, acidification, coagulation and filtration.
