摘要： The invention relates to a device for dispensing a liquid additive into a fuel circulation circuit for an internal combustion engine, comprising a reservoir (12) of liquid additive allowing an additive to be distributed into the fuel circulation circuit by means of a distribution line (16), characterized in that it comprises an additive chamber (22) in communication with the fuel circulation circuit and at least one wall (32) that is mobile and fluidtight between said additive chamber and the additive reservoir which, on the one hand, provides a fluidtight division and, on the other hand, maintains equal pressure between the additive in the additive reservoir and the fuel in the additive chamber.

摘要： The invention describes a method for separating a mandelic compound in salified form from an aqueous reaction medium resulting from the condensation reaction of a hydroxylated aromatic compound with glyoxylic acid in a basic medium, said method comprising a) decanting said reaction medium in such a way as to recover an organic phase formed from the excess of said aromatic compound and an aqueous phase formed from said mandelic compound and a quantity of the excess of said aromatic compound and b) bringing said aqueous phase into contact with an adsorbent support, resulting in the selective adsorption of said aromatic compound and the recovery of an aqueous flow comprising said mandelic compound in salified form, which is subjected to an oxidation step before being converted into hydroxyaromatic aldehyde by electrodialysis.

摘要： The invention relates to a composition essentially consisting of a zirconia-ceria mixed oxide, with a zirconia content of at least 40 wt. % and, after 4 hours of calcination at 1000°C, a specific surface area of at least 25 m
2 /g and a quantity of mobile oxygen between 200°C and 400°C of at least 0.5 ml O
2 /g. Said composition is produced using a method wherein a mixture of cerium and zirconium compounds is continuously reacted with a basic compound in a reactor, with a maximum residence time of the reactive medium in the mixture zone of the reactor of 100 milliseconds; and the precipitate is heated then brought into contact with a surfactant before being calcinated.-

摘要： A process for extraction of ferulic acid present in an aqueous phase, obtained by treatment of at least one plant material, and also containing polysaccharides, is described, said process comprising at least the following steps: 1) the treatment of said plant material followed by a solid/liquid separation to recover a solid phase and an aqueous liquid phase comprising the ferulic acid and said polysaccharides, 2) the treatment of said liquid phase to selectively separate, on the one hand, the polysaccharides and, on the other hand, the ferulic acid present in an aqueous fraction, 3) the concentration of said aqueous fraction containing the ferulic acid so as to recover a ferulic acid-concentrated stream, 4) the recovery of the ferulic acid in solid form.
