Abstract: A coupling agent formulation for cellulosic material-polymer composites is provided. The formulation includes a) at least one organic peroxide; and b) at least one of i) at least one zinc-containing reagent; and/or ii) at least one silicon-containing reagent. The coupling agent formulations produce polymer matrix cellulosic material composites with improved strength and aging characteristics. The improved strength may be related to physical properties such as improved stiffness, toughness or tensile strength. A masterbatch utilizing the coupling agent formulation is provided, as well as a method making the masterbatch.

Abstract: This invention provides improvements to processes for making granular lignin from black liquor. One of the improvements is that the use of a pre-carbonation column reduces the CO2 flow into the sparger of a carbonation column. The pre-carbonation column is used to reduce the pH of the black liquor to about 12. Another improvement is that it has been found that coalescing droplets into a bulk liquid-lignin phase can be enhanced by placing the exit of the carbonation column at or slightly beneath carbonated black liquor/liquid-lignin interface. It has also been found that operating the carbonation settler at a low pressure and pumping the liquid- lignin from the carbonation settler to the acidification reactor operating at a higher pressure allows recycling the vent gas from the acidification reactor to the pre-carbonation column. The invention also provides for a vent gas absorber.

Abstract: The present invention describes a method of dissolving cellulose, said method comprising: dissolving cellulose in an alkali solution;-filtering the dissolved cellulose, thereby forming a filtered dissolved cellulose solution and a filter reject;- mixing said filter reject having a first viscosity value with a dissolution liquid having a second viscosity value, wherein the second viscosity value is lower than the first viscosity value, to provide a diluted reject stream having a third viscosity value being lower than the first viscosity value of the filter reject;and- separating inhomogeneities from the diluted reject stream.

Abstract: A method for processing a bark press water from sawmills and/or pulp mills is disclosed. According to the disclosure, the method comprises a) filtration of the bark press water to provide a bark press water filtrate having a particle size of less than 100 µm, and b) concentrating the bark press water filtrate to a level of at least 10 % dry weight and thereby providing a first fraction of concentrated bark press water, comprising tannic compounds; and a second fraction of purified bark press water.
