Abstract: A binder pitch material includes a petroleum pitch and asphalt fraction obtained from petroleum crude oil and has a significantly lower polycyclic aromatic hydrocarbon composition than a coal tar pitch having a like softening point. The pitch material is useful as a binder material for various applications such as clay pigeons.

Abstract: The present invention provides a way to increase the softening point of heavier hydrocarbons in a relatively low cost and low pressure process using superheated steam to i) increase the carbon yield of the heavier hydrocarbons, while simultaneously ii) removing volatile components with a steam stripping process.

Abstract: Fractions derived from a high sulfur content crude oil, having a sulfur content of about 2 wt. % or greater, is hydrotreated to produce a petroleum pitch not only having a low sulfur content of about 1 wt % or less but also a low polycyclic aromatic hydrocarbon (PAH) content of about 13,000 mg/kg or less.

Abstract: A pitch coated board and method of manufacture are disclosed. A porous or fibrous material, is coated and partially impregnated with a thin layer, less than 10 mil in thickness, of a petroleum or coal tar pitch. A high softening point, above 200F, coal tar or petroleum pitch is heated, then preferably roller coated on a fibrous material, then cooled within 1-2 seconds or less, to produce the pitch coated material. The porous material may be heated, preferably superficially, prior to application of the pitch to facilitate some penetration.

Abstract: A high coking value pitch with a relatively low softening point is disclosed. A pitch is distilled or thermally processed to produce an intermediate pitch with an increased coking value and relatively high softening point, then blended with a cutter solvent of a liquid hydrocarbon stream to form a product pitch. The process may be used to increase the coking value of either petroleum or coal tar pitch. Preferably the cutter solvent is methylnaphthalene, or a highly aromatic, low viscosity oil or similar aromatic rich stream having a substantially lower boiling point than the intermediate pitch product.
