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.

Petroleum hydrocarbon binder with reduced polycyclic aromatic hydrocarbon content

A low viscosity, high coking value petroleum tar material having a high coking value as compared to standard petroleum tars and containing at least one biodiesel material dissolved therein, and a method for producing such material, are disclosed.

Low viscosity, high carbon yield pitch product

A low-viscosity, high-softening point heavy hydrocarbon material having a viscosity-reducing amount of at least one biodiesel material dissolved in a heavy hydrocarbon, and a method for producing such low-viscosity, high-softening point heavy hydrocarbon material are disclosed.

Viscosity modification of heavy hydrocarbons

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.

Method of producing high softening point pitch

A sealer base comprising at least one anti-wear agent comprising aliphatic carboxylic acids and aliphatic polyamides is disclosed.

Use of anti-strip agents to improve wear characteristics of pavement sealer

A low viscosity, high softening point heavy hydrocarbon material having a viscosity reducing amount of at least one dihydric alcohol dissolved therein, and a method for producing such heavy hydrocarbon material, are disclosed.

Viscosity modification of heavy hydrocarbons using dihydric alcohols

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.
