摘要：The present invention comprises an improved method for refining cellulose thatproduces a highly refined cellulosic material. The method comprises soaking raw materialin a mild NaOH using reduced temperatures and pressures, and refining the material witha plate refiner so that a waste water stream is reduced in volume and has a pH within arange of 8 to 9. The present invention also comprises a HRC gel having a ligninconcentration of at least about one (1)% by weight, and a water retention capacity ofabout 25 to at least about 56 g HO/g dry HRC.
