Abstract
Provided is a mercury adsorbent that can efficiently adsorb and remove mercury and/or a mercury compound contained in a liquid hydrocarbon and can suppress corrosive action even when used for a long time. The mercury adsorbent comprises an activated carbon including a mineral acid supported thereon, the activated carbon having a specific surface area of 1000 m2/g or larger and a volume of micropores of 80 cm3/g or larger, each of the micropores having a pore radius of 8 Å or smaller, and the mercury adsorbent has a moisture content of from 0.1 to 3 wt %.
