Liquid-phase adsorption process for removing and concentrating heteroatom compounds in hydrocarbons

Disclosed is a liquid phase adsorption process for removing and concentrating heteroatom compounds in hydrocarbons (HCH), comprising the steps of adsorption, copurging and regeneration. In the adsorption step, a liquid hydrocarbon stream is fed to an adsorber, which adsorbs HCH and returns adsorption effluent. In the copurging step, HCH, which are extracted from the previous regeneration, are applied to the adsorber, displacing copurging effluent. In the regeneration step, a polar solvent is flowed through the adsorber, purging HCH. Most of the HCH are then set aside for being used in the next copurging step while a small amount of the HCH are taken out from the process as HCH product. The present invention is economically advantageous in effectively removing HCH from the hydrocarbon stream and increasing HCH concentrations within HCH product.
