摘要:
This invention relates to a commercially viable process for extracting oxygenates from a hydrocarbon stream, typically a fraction of the condensation product of a Fischer-Tropsch reaction, while preserving the olefin content of the condensation product. The oxygenate extraction process is a liquid-liquid extraction process that takes place in an extraction column using a polar organic solvent, such as methanol, and water as the solvent, wherein the polar organic solvent and water are added separately to the extraction column.
