Aqueous carbonaceous slurries
Patent
·
OSTI ID:5296228
Aqueous carbonaceous slurries having reduced viscosity, a stabilized network of coal in water and improved pumpability are obtained by having present a salt of naphthalenesulfonic acid formaldehyde condensate and at least one water soluble polymer selected from the group consisting of gum karaya, mixtures of gum karaya and polyacrylamide and polysaccaride modified with polyacrylate. For example, a mixture of 61.5% by weight of ammonium naphthalenesulfonic acid formaldehyde condensate and 38.5% by weight of gum karaya can be added to an aqueous coal slurry in an amount of 0.13% by weight of the slurry.
