Abstract
The present invention concerns the elimination of heavy metals, in particular mercury and possibly arsenic and lead, present in a gaseous or liquid effluent by means of a capture mass comprising a support essentially based on alumina obtained by the gel method and at least one element selected from the group constituted by copper, molybdenum, tungsten, iron, nickel and cobalt. The invention is advantageously applicable to the treatment of gas of industrial origin, synthesis gas, natural gas, gas phase condensates and liquid hydrocarbon feeds.
