PROCESS FOR REMOVAL OF NITROGEN AND POLY-NUCLEAR AROMATICS FROM HYDROCRACKER AND FCC FEEDSTOCKS |
摘要 |
A feedstream to a hydrocracking unit is treated to remove or reduce the content of polynuclear aromatics and nitrogen-containing compounds by contacting the feedstream with an adsorbent compound selected from attapulgus clay, alumina, silica gel and activated carbon in a fixed bed or slurry column and separating the treated feedstream that is lower in the undesired compounds from the adsorbent material. The adsorbent can be mixed with a solvent for the undesired compounds and stripped for re-use. |
