| 摘要 |
A process for reducing the nitrogen content of shale oil by polymerizing the pyrrole compounds present in the shale oil by conditioning the shale oil with at least one of the following steps of acidifying the shale oil with a strong acid, heating the shale oil to at least about 85 DEG C., oxygenating the shale oil with an oxygen-supplying gas, and irradiating the shale oil with actinic radiation. The resulting pyrrole polymers are insoluble in the shale oil and are separated by liquid/solid separation techniques.
