  • Aqueous, pumpable fluids from solid carbonaceous materials
    Patent number: 6444711
    Abstract: The invention is a method for forming a solid carbonaceous material into a pumpable fluid by combining the solid with an aqueous treatment solution and then subjecting the mixture to shearing forces. The solid carbonaceous material can be deasphalter unit rock (“DAU rock”), coke, and mixtures of DAU rock and coke. Aqueous treatment solutions contain a water soluble polymer.

  • Sealer from SDA asphalt
    Patent number: 6403659
    Abstract: An asphalt based sealer for driveways and the like is disclosed. The material uses a blend of solvent deasphalted (SDA) asphalt blended with a cutter stock as the binder or sealer base. Driveway sealer (an emulsion of clay, water and binder) made with this binder has acceptable durability and can be essentially free of coal tar pitch, greatly reducing the toxicity and odor of the sealer.

  • Processes of purifying a dispersion and making inkjet inks
    Patent number: 6328894
    Abstract: A process to purify and classify a dispersion containing stabilized particles having counterions and ions as well as free species is disclosed. The solution may comprise an aqueous media, a solvent media, or a combination of both and can include more than one type of aqueous and/or solvent solutions. The process includes at least the steps, in any order, of substantially removing the particles having sizes above about 1 micron, preferably above 0.5 micron; substantially removing the free species; and exchanging at least a portion of the counterions that are a part of the stabilized particles. The process disclosed is especially useful in purifying dispersions where the ionic stabilized colloidal particles are carbon black having attached organic groups comprising at least one ionic group, or at least one ionizable group, or mixtures thereof.

  • Driveway sealer using phase stable pourable pitch
    Patent number: 6267809
    Abstract: A low softening point pitch is disclosed. A high melting point (100° C.+) pitch is blended with an aromatic rich liquid hydrocarbon stream to form a pourable pitch mixture having a softening point of 30-50° C. which can be used as a partial or complete replacement for coal tar pitch used in driveway sealer and other sealer and coating applications. Driveway sealer (an emulsion of clay, water and binder) made with this pitch has enhanced durability. The low softening point pitch, even when blended with coal tar pitch, is phase stable on storage.
