Isolation method for water insoluble components of a biomass
11174355 · 2021-11-16 · ·

The process includes pretreating the biomass with a first basic solution such as sodium hydroxide and mechanically altering the fibers to provide a fluidized biomass. The fluidized biomass is then subjected to high frequency pulses and shear forces without denaturing the individual components of the biomass. The biomass is then subjected to compressive force to separate a first liquid fraction from a first fractionated biomass. The first fractionated biomass may again then be subjected to the same high frequency pulses and shear forces as previously, particularly if there are hemicellulose and/or sugars still present in the first fractionated biomass. Compressive forces are used to separate a second liquid fraction from a second fractionated biomass. The second fractionated biomass is subjected to oxidation such as with hydrogen peroxide at a pH of 8 to 12. The second fractioned biomass is then subjected to compressive forces to separate one or more water insoluble components of the biomass in water soluble form.

Methods of making fabric-creped absorbent cellulosic sheets

A method of making a fabric-creped absorbent cellulosic sheet. The method includes compactively dewatering a papermaking furnish to form a web having a consistency of about thirty percent to about sixty percent, creping the web under pressure in a creping nip between a transfer surface and a structuring fabric, and drying the web to form the absorbent cellulosic sheet. The absorbent sheet has SAT capacities of at least about 9.5 g/g and at least about 500 g/m.sup.2. A creping ratio is defined by the speed of the transfer surface relative to the speed of the structuring fabric, and the creping ratio is less than about 25%.
