Agglomerated cellulosic particles

A cellulosic particle, especially useful as a cat litter, is manufactured by agglomerating a fibrous cellulosic feed material in the presence of water, compacting the surface of the agglomerated particles, and drying the particles. The water causes hydrogen bonding between the films. Paper mill sludge or biberized waste paper is moistened with water in blender 33, agglomerated in rotating drum 41 or a rotating disc agglomeration to form spherical particles which are then compacted to remove projecting films by the action of fluidized bed dryer 46 or a further rotating drum. In the embodiment of Figure 4 agglomeration compaction and drying are accomplished in a single long rotating drum. ...

Methods for preparing stable aqueous dispersions of cellulose and applications to coating products such as glass products

Aqueous dispersions of cellulose are produced by hydrolysing either natural or regenerated cellulose in an acid medium to form "level-off D.P. cellulose," and mechanically disintegrating the hydrolysed cellulose in an aqueous medium. "Level-off D.P. cellulose" is defined as cellulose which has been hydrolysed, e.g. by treatment with a dilute aqueous solution of a highly ionizable mineral acid, preferably a hot aqueous solution of hydrochloric acid, until it has reached a substantially constant "degree of polymerization" or molecular weight. The hydrolysed cellulose may be mechanically disintegrated in an acid aqueous medium and then washed free from acid, or may be washed free from acid before disintegration in an aqueous medium. The latter may have a pH from 1-11, and at least 1% of the cellulose may be reduced to not over one micron particle size. In an example, viscose rayon filaments are contacted for about 15 minutes with a 2,5 normal solution of hydrochloric acid, filtered off and ...
