摘要:
The invention concerns the use of supported catalysts comprising at least one metal or metallic compound of a metal from group VI and/or group VIII deposited on a support essentially constituted by β silicon carbide in a process for selective hydrodesulphurization of an olefinic hydrocarbon feed that is substantially free of polynuclear aromatics and metals.The invention can be used to carry out deep desulphurization of catalytically cracked gasoline cuts with very limited saturation of olefins and thus a minimum loss of octane number.
摘要:
A process for purification by adsorption of a hydrocarbon feedstock that uses a novel adsorption agent is described. This adsorption agent is a spent solid adsorbent that has been used in a first application of catalytic treatment of hydrocarbon feedstocks, or of adsorption, and whose adsorption or catalytic performance levels are degraded such that its use for the first application has become impossible. The use of this spent solid adsorbent for the purification of hydrocarbon feedstocks by adsorption does not require specific treatment in advance, in particular not heat treatment.

摘要:
For desulfurization and, if necessary, for denitrification of hydrocarbon fractions the hydrocarbon mixture is brought into contact with a non-aqueous ionic liquid of general formula Q+A−, wherein Q+ is a ammonium, phosphonium or sulfonium cation, that contains at least one alkylating agent of the formula RX−, making it possible to form ionic sulfur-containing derivatives (and, if necessary, nitrogen-containing derivatives) that have a preferred solubility in the ionic liquid; and the ionic liquid is separated from the hydrocarbon mixture that is low in sulfur and nitrogen by decanting.
