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

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