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.

Capture mass composed of elemental sulphur deposited on a porous support for capturing heavy metals

The invention describes an improved process for deep desulfurization of a gas-oil-type hydrocarbon fraction that comprises a catalytic hydrodesulfurization unit that is preceded by a unit for adsorption of the nitrogen compounds that inhibit the hydrodesulfurization reaction.

Process for desulfurization and denitration of a gas-oil-type hydrocarbon fraction that contains nitrogen compounds

The invention relates to a process for the production of thermally-integrated hydrogen from a liquid hydrocarbon feedstock that contains sulfur-containing compounds that comprise at least one stage for heating the liquid hydrocarbon feedstock by indirect heat exchange with a hot stream, a stage for desulfurizing the heated hydrocarbon feedstock, a stage for evaporating the desulfurized hydrocarbon feedstock by indirect heat exchange with the hot stream that exits from the autothermal reformer, a stage for autothermal reforming of the hydrocarbon feedstock, and a stage wherein the carbon monoxide content in the hydrogen-rich gas that is produced is reduced in a reactor for converting carbon monoxide with water. The invention also relates to the hydrogen production installation that corresponds to this process.

Process for the production of hydrogen with a thermally-integrated desulfurization unit

The invention relates to a treatment process of a sulphur-containing hydrocarbon fraction, comprising the following steps:

Process for deep desulphurization of cracking gasolines with a small loss of octane number

A process for reducing the quantity of sulphur present in a hydrocarbon feed such as a gasoline or a gas oil, comprises:

Process for desulphurizing a hydrocarbon feed by adsorption/desorption

The invention relates to a process for the desulfurization of gasolines comprising a stage for fractionation of said gasoline into a light fraction that comprises thiophenic compounds such as thiophene or methylthiophenes, and a heavy fraction that concentrates the heaviest aromatic sulfur-containing compounds. The heavy fraction is treated by hydrodesulfurization, while the light fraction is brought into contact with a solid adsorbent that makes it possible to eliminate at least partially said light thiophenic compounds, whereby said adsorbent solid is regenerated by a flow internal to the process.

Process for the desulfurization of gasolines comprising a desulfurization by adsorption of the light fraction and a hydrodesulfurization of the heavy fraction

The invention describes the application of caesium-exchanged X, Y or LSX type faujasite zeolites for intense desulphurization of FCC gasoline, and to a method for preparing said zeolites.

Use of caesium-exchanged faujasite type zeolites for intense desulphurization of a gasoline cut

The invention concerns a process for desulphurizing gasoline comprising a step for fractionating said gasoline under conditions in which a light fraction comprising the lightest thiophene compounds such as thiophene or methylthiophenes and a heavy fraction concentrating the heaviest aromatic sulphur-containing compounds are obtained. Said heavy fraction is treated by hydrodesulphurization, while the light fraction is brought into contact with a solid adsorbant to eliminate at least a portion of said light thiophene compounds.
