Activated carbon is prepared specially by activating carbonaceous material in a circumstance comprising water vapor less than 15% on volume basis and providing thus treated activated carbon carries alkaline or alkaline earth metal sulfide in it. Thus prepared activated carbon or that carrying these compound provides for method of eliminating mercury and its compounds from liquid hydrocarbons substantially completely contained at a slight amount in it.
