Method of eliminating mercury from liquid hydrocarbons

摘要

Activated carbon is prepared specially by means of activating carbonaceous material in a circumstance comprising water vapor less than 15 % on volume basis and providing the thus treated activated carbon to carry alkaline or alkaline earth metal sulfide in it. The thus prepared activated carbon or that carrying these compounds provide for a method of eliminating mercury and its compounds from liquid hydrocarbons substantially completely which are contained in it at a slight amount. Liquid hydrocarbons containing mercury or sulfur will harm catalysts which are often applied during processing such intermediates of petroleum products and petrochemical products. Thus the present method is advantageous to processing of such oil intermediates.
