| 摘要 |
In some embodiments, the invention is a method of removing sulfur from a hydrocarbon feed using the steps of dissolving metallic sodium in a first so lvent, combining the sodium/first solvent solution with a sulfur-free alkane or cycloalkane second solvent, vaporizing the first solvent from sodium/fir st solvent/second solvent combination to transfer the dissolved metallic sod ium into the second solvent, and then combine the resultant liquid with a li quid hydrocarbon feed containing an organosulfur species. The resulting stre am is combined with a hydrogen donor. The combination is heated and pressuri zed to form a liquid hydrocarbon product containing sodium sulfide. The liqu id hydrocarbon product containing sodium sulfide is then cooled, and the sod ium sulfide is extracted. The extracted sodium sulfide is then processed in a sodium sulfur cell to regenerate the sodium and recycle it to the feed.
