    Abstract: Process for producing a light gasoline having a sulfur content of less than 10 ppm by weight, with respect to the total weight of the light gasoline, starting from a gasoline containing sulfur compounds, olefins and diolefins, which process includes a) a stage of selective hydrogenation to hydrogenate the diolefins and a reaction for increasing the molecular weight of a part of the sulfur compounds; b) a stage separating the effluent obtained from stage a) into a gaseous fraction, a light gasoline cut and a heavy gasoline cut, stage b) being carried out in a fractionation column containing n plates, n being an integer of 20 or more, the first plate being the reboiler and the plate “n” being the condenser, wherein the light gasoline cut is withdrawn from the fractionation column at the plate “n-i”, with i being 1 to 10.

    Abstract: The present invention relates to a crosslinkable electrolyte formulation comprising at least: —a lithium salt or a mixture of lithium salts—a hydrocarbon molecule comprising two thiol functions—an unsaturated hydrocarbon molecule comprising two C═C double bonds—a crosslinking agent, said crosslinking agent being a molecule carrying at least three C═C double bonds; in which the [C═C double bond]/[thiols] molar ratio is of between 1 and 1.1. The invention also relates to a process for the preparation of a crosslinked solid electrolyte by means of said formulation, and also to the use of said crosslinked solid electrolyte as solid electrolyte of an all-solid-state Li-ion battery or as component of the positive (posolyte or catholyte) or negative (negolyte or anolyte) electrode of an electrochemical system.

    Abstract: The present invention is a method for determining the position of a source emitting at least one of a gaseous compound and particles in a geographical area, comprising measuring the gaseous compound concentration, the wind direction and speed for different predefined consecutive geographical positions to deviate by at most 45° from an instantaneous or average wind direction. At least one pair of a consecutive minimum and maximum of the curve is subsequently determined, and the position of the emission source is determined from the positions of the mobile measurement system corresponding to the maxima of the pairs, the time gaps between the maximum and minimum of the pairs, and average wind speeds and directions between the minimum and maximum of the pairs.

    Abstract: Process for trapping mercaptans contained in a sulfur-containing hydrocarbon feedstock, in the presence of a trapping mass comprising an active phase based on at least one group VIII, IB or IIB metal, and a mesoporous or macroporous support, said trapping mass comprising a specific surface area of between 120 m2/g and 350 m2/g, and: the volume of mesopores with a diameter greater than or equal to 2 nm and less than 50 nm corresponds to between 40% and 70% by volume of the total pore volume of said trapping mass; the volume of macropores with a diameter greater than or equal to 50 nm corresponds to between 30% and 60% by volume of the total pore volume of said trapping mass.

    Abstract: The present invention relates to a process and a device for the conversion of aromatic compounds, in which the aromatic compounds of a hydrocarbon feedstock (1) comprising aromatic compounds containing 9 carbon atoms are isomerized in an isomerization unit (A) in the presence of a bifunctional isomerization catalyst having a hydro/dehydrogenating function and a hydroisomerizing function, to produce an isomerization effluent (10) enriched in trimethylbenzenes. The present invention also relates to a process and a device for the production of aromatic compounds, comprising the process and the device for the conversion of aromatic compounds.
