(54) Process for eliminating mercury form liquid hydrocarbons


(57) The present invention provides a process for eliminating mercury and mercury compounds from liquid hydrocarbons in a naphthametal elimination process having an adsorption treatment zone provided with a packed layer of mercury adsorbent, comprising the steps of:

(a) introducing the mercury-containing liquid hydrocarbon into the adsorption treatment zone;

(b) contacting the mercury-containing liquid hydrocarbon with the packed layer of mercury adsorbent in the adsorption treatment zone at a temperature of 10°C to 200°C and a LV value of 1 cm/min to 100 cm/min; and

(c) removing treated liquid hydrocarbon from the adsorption treatment zone.


According to this mercury elimination process, the mercury present in liquid hydrocarbons can be almost completely, efficiently and continuously removed through adsorption treatment regardless of the amount of mercury present and regardless of the presence of any sulfur compounds.
