METHOD FOR TREATING COAL TAR USING REACTIVE DISTILLATION |
| 摘要 |
Methods of treating coal tar using reactive distillation are described. The methods include introducing a coal tar stream into a reactive distillation zone which has a reaction zone and a separation zone. The reaction zone contains a hydrotreating catalyst and an absorbent. The coal tar stream is contacted with a hydrogen stream in the reaction zone to remove contaminants from the coal tar stream, and the treated coal tar stream is separated into at least two fractions. |

1. A method of treating coal tar using reactive distillation comprising:
introducing a coal tar stream into a reactive distillation zone, the reactive distillation zone comprising a reaction zone and a separation zone, the reaction zone containing a hydrotreating catalyst and an absorbent; contacting the coal tar stream with a hydrogen stream in the reaction zone to remove sulfur compounds, nitrogen compounds, oxygenates, and metals from the coal tar stream; and separating the treated coal tar stream into at least two fractions. |
