摘要： 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.

摘要： 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.

摘要： A 40 petroleum pitch is disclosed. A high melting point petroleum pitch is blended with a high boiling normally liquid petroleum derived hydrocarbon stream to form a mixture having a softening point of 35-45 C. as a partial or complete replacement for coal tar pitch used in driveway sealer and other sealer applications. Driveway sealer (an emulsion of clay, water and binder) made with A 40 has excellent durability and can have a greatly reduced amount of, or be essentially free of, coal tar pitch, greatly reducing the toxicity and odor of the sealer.

摘要： A better asphalt based sealer for driveways and the like is disclosed. The material uses as a hybrid sealer base or binder comprising a blend of pitch, asphaltic material and cut-back oil as a partial or complete replacement for pure coal tar materials. Driveway sealer (an emulsion of clay, water and binder) made with this hybrid binder has significantly better durability and color than like materials made with a binder of asphalt and cut-back oil. The hybrid binder has less odor and fewer toxins than a binder made of pure coal tar material.
