摘要
The invention relates to a process for enhancing demetallation of metals containing hydrocarbonaceous feedstocks by contacting a metals containing hydrocarbonaceous feedstock at a sufficient temperature and pressure with an additive containing a polyoxyalkylene moiety said additive having preferential insolubility in alkane deasphalting solvent to produce an additive treated feedstock; and then contacting the resulting product with an effective deasphalting solvent to produce a deasphalted oil having a decreased metals content and an insoluble metals containing phase.
