Abstract
The invention discloses a method for extracting a plurality of chemicals from a coal tar, which comprises such procedures as heating the coal tar to 120-130 DEG C, dehydrating, fore running, separating, fine rectifying, and heavy-oil distilling, and getting 95 naphthalene, methyl naphthalene, anthracene oil, asphalt and heavy oil. The invention is of simple process, easy operation, rectifies coal tar several times; the extracted chemical products are of steady quality, the naphthalene is of high concentration, and the asphalt is of good quality. The invention is of low energy consumption, hence improves better the added value in processing coal tar in China.
