The present invention relates to an adsorbent comprising an alumina support and at least one alkali element, said adsorbent being obtained by introducing at least one alkali element, identical to or different from sodium, onto an alumina support the sodium content of which, expressed as NaO equivalent, before the introduction of the alkali element or elements, is comprised between 1000 and 5000 ppm by weight with respect to the total weight of the support. The invention also relates to processes for the preparation of said adsorbent and use thereof in a process for the elimination of acidic molecules such as COS and/or CO.

Alumina-based adsorbent containing sodium and doped with an alkali element for capturing acidic molecules

The present invention concerns a hydrotreatment catalyst comprising a support, at least one metal selected from group VIB and at least one metal selected from group VIII of the periodic table, the quantity of metal from group VIB, expressed as the oxides, being in the range 6% to 25% by weight with respect to the total catalyst weight, the quantity of metal from group VIII, expressed as the oxides, being in the range 0.5% to 7% by weight with respect to the total catalyst weight, the support comprising at least 90% by weight of alumina, in which said alumina is obtained from a mixed and extruded boehmite gel, and in which the specific surface area of said catalyst is in the range 60 to 250 m/g.

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.

Performance trapping mass and use thereof in heavy metal trapping

The present invention concerns the elimination of heavy metals, in particular mercury and possibly arsenic and lead, present in a dry or moist gaseous effluent () by means of a capture mass () comprising a porous support at least part of which is of low mesoporosity and an active phase based on sulphur. The invention is advantageously applicable to the treatment of gas of industrial origin, synthesis gas or natural gas.
