ABSTRACT:
The invention provides a method for removing mercury from a liquid hydrocarbon feed material by (a) removing those components having a higher molecular weight than the desired hydrocarbon from the feed material, (b) removing water from the feed material, and thereafter (c) removing mercury from the feed material. Mercury can be removed to an extremely low concentration of 0.001 ppm or lower from a wide variety of liquid hydrocarbon feed materials containing either a relatively large amount or a trace amount of mercury.
