Abstract: A method for continuous production of hydrocarbons from synthesis gas in the presence of a cobalt-based catalyst which comprises a step of providing synthesis gas from a source (1) of synthesis gas in a Fischer-Tropsch synthesis reactor (4). The method also includes the following steps: a) conditioning of the catalyst in reduced state in a conditioning reactor (2) by contact with a flow of reducing gas from a synthesis gas source supplying the synthesis reactor, the reducing conditioning gas comprising carbon monoxide (CO) or a mixture comprising hydrogen (H2) and carbon monoxide (CO), the H2/CO molar ratio of which is between 0.1 and 0.9, at a temperature between 200 and 500° C., and a total pressure between 0.1 and 5 MPa and under a gas flow between 1 and 20 NI/h/g of catalyst to be treated, b) supply of reduced catalyst conditioned in step a) to the synthesis reactor (4).

Abstract: The invention of the current application is a process for eliminating arsenic from a hydrocarbon feed which is at least partially liquid, including steps a and b.Step a includes bringing the hydrocarbon feed and hydrogen into contact with a first capture mass including a support and at least one metal M1 from group VIB and at least two metals M2 and M3 from group VIII.Step b includes bringing the hydrocarbon feed and hydrogen into contact with a second capture mass in the sulphide form including a support and nickel, the quantity of nickel being at least 5% by weight of NiO with respect to the total weight of the second capture mass.Step a) is either carried out before step b) or carried out simultaneously with step b).
