Title:
石油ピッチを含有する高品質アスファルト及びその製造方法
Document Type and Number:
Japanese Patent JP4947473
Kind Code:
B2
Abstract:
A high quality asphalt containing pitch is generated as a by-product in a solvent deasphalting process and a method of preparing the same. The pitch is obtained by subjecting a mixture comprising a first vacuum residue and a first petroleum distillate, which is lighter than the vacuum residue and has high amounts of aromatic and resin, to solvent deasphalting. The operation conditions of the solvent deasphalting process are appropriately controlled, such that aromatic and resin components contained in the atmospheric residue and vacuum residue can be distributed to the pitch, and as well, a saturate can be removed.
