Abstract:

An omnibus process of pulping and bleaching lignocellulosic materials in which a charge of a lignocellulosic material is biopulped and/or water extracted prior to pulping and bleaching. The lignocellulosic material may be mechanically pulped and bleached in the presence of an enzyme that breaks lignin-carbohydrate complexes. The aqueous extract in embodiments including a water extract step is separated into acetic acid and hemicellulose sugar aqueous solutions.

Filed:

May 29, 1997

Appl. No.:

8/865783

Inventors:

Bandaru V. Ramarao - Dewitt NY

Assignee:

The Research Foundation of State University of New York - Albany NY

International Classification:

G01N 3334

US Classification:

162198

Abstract:

Method and apparatus are presented for use in a papermaking process for determining permeability and/or compressibility characteristics of a pulp suspension within the process. The method/apparatus includes monitoring height of pulp suspension within one or more test columns as a function of time while allowing pulp suspension drainage from each test column. At least one parameter representative of permeability or compressibility of the pulp suspension is determined, via computer processing, using the monitored height as a function of time of the pulp suspension within the test column. The at least one parameter representative of permeability or compressibility can comprise specific surface area (S. sub. w), specific volume (v. sub. f) compressibility constant m or compressibility constant n for the pulp suspension.

International Classification:

C12P 19/14
C12P 19/02

US Classification:

435 99, 4352891

Abstract:

A method for processing a stream of cellulosic fines containing inorganic particles, to increase a hydrolysis yield of polysaccharide degradation enzymes, such fines in a waste stream from a recycled packaging paper mill to produce a stream of fermentable sugars, comprising treating the fines with a surfactant which selectively binds to the inorganic particles and which reduces binding to the inorganic particles by the polysaccharide degradation enzymes, and degrading polysaccharides in the waste stream with the polysaccharide degradation enzymes.
