Process for producing petroleum containing very small amount of nitrogen |
| abstract |
The present invention relates to a high efficiency liquid-liquid extraction method for removing nitrogen compounds, especially basic nitrogen compounds, from aromatic light petroleum with good recovery rate using deionized water which can be acidified as extractant. The product is an aromatic hydrocarbon containing a very small amount of nitrogen poisons capable of deactivating acidic catalysts. The extracted oil is a suitable feedstock for future catalytic processes catalyzed by high performance solid catalysts which are very sensitive to nitrogen poisons. n n Light petroleum, aromatic hydrocarbons, nitrogen poisons, feedstocks, petrochemicals |
