The present invention relates to : an organosulfur absorbent; a method for producing the same; a method for absorbing organosulfur compound from liquid petroleum oil; and a method for regenerating organosulfur absorbent. The organosulfur absorbent includes 0.5-30 wt% of an active ingredient including rear earth and transition metal and 70-95.5 wt% of a porous support. Therefore, the organosulfur absorbent has excellent selectivity of absorbing the organosulfur compound, excellent long-term stability, and excellent regeneration properties, and thus can lower density of the organosulfur compound contained in the petroleum oil down to 1 ppm or less.COPYRIGHT KIPO 2015
