A method for preparing a compound of formula RSH where R represents an alkyl group, by gas-phase catalytic reaction of hydrogen sulfide with a compound of formula ROH, in the presence of a solid catalyst, according to which method the reaction is performed in the presence of a catalyst which includes one or several pure or mixed rare-earth oxide(s), one or several pure or mixed rare-earth sulfide(s), or one or several pure or mixed rare-earth oxysulfide(s). When the rare earth is lanthanum, the catalyst is a mixed oxide of lanthanum and of at least one metal selected from rare earths or not and when the rare earth is cerium, the catalyst is supported on an alumina.

Process for preparing a compound of formula RSH by hydrosulfurization

The fuel filter () contains a filter element () and an additive tank () in a housing (). The filter element is engaged against the removable cover () of the housing and has a filter medium () extending in an annular manner around an inner space (). An additive release device () extends into this inner space () to distribute liquid additive from the tank () into a fuel circulation circuit for an internal combustion engine. The additive selectively flows into a sealed distribution channel (DC) of the device () depending on an open or closed configuration of an actuator component () associated with the distribution channel. The distribution channel (DC) opens into a fuel channel () of the cover () that has a larger cross-section than the distribution channel (DC).

Fuel filter with additive release device

In a filter cartridge (CC) for a fuel filter, the filter element () and the additive module are connected and typically stacked so as to allow them to be integrally inserted into a filter housing. The substantially annular filter medium () delimits an inner space () into which at least one part () of the attachment end of the additive module can be engaged. The liquid additive is stored in a casing forming a tank () that is placed at a fuel pressure and delimits an internal volume (V) that can be varied so as to maintain an identical pressure between the liquid additive and the fuel at the periphery (V) of the tank (). The additive module has an external connection () with a liquid additive outlet pipe (), said external connection () including sealing means () for automatically closing the outlet pipe in a fluidtight manner when the external connection is in a disengaged state.
