Abstract: Processes for the production of acetic acid by carbonylation of methanol and reactive derivatives thereof in a liquid phase reaction medium, wherein the reaction medium comprises a finite amount of water, a homogeneous catalyst, an alkyl halide promoter, and a catalyst stabilizer/co-promoter comprising an imidazolium cation R1R2Im+ as an iodide salt, wherein R1 and R2 are each independently a substituted or unsubstituted alkyl or cycloalkyl, with the proviso that R1 and R2 are not the same.

Abstract: An assembly including a gas turbine engine and a nacelle in which the engine is housed, the nacelle including an air intake fairing that forms an air inlet and includes: a member for deflecting foreign objects, which together with the fairing, forms an air intake duct; and, downstream from the deflecting member, a secondary deflecting channel, and a main channel for supplying air to the engine. The air intake duct is configured to deflect at least some of the foreign objects sucked in through the air inlet towards the secondary deflecting channel. The secondary deflecting channel is shaped such that the flow velocity of the air flowing therethrough increases from upstream to downstream, the secondary channel having an outlet with an opening leading into the outer wall of the nacelle.

Abstract: A method for the selective production of ordered carbon nanotubes includes decomposition of a carbon source in the gaseous state in contact with at least one solid catalyst, taking the form of metallic particles borne by carrier grains. The catalyst grains are adapted so as to be able to form a fluidised bed containing between 1% and 5% by weight of metallic particles having average dimensions of between 1 nm and 10 nm. The decomposition takes place in a fluidised bed of catalyst grains. The method can be used to obtain pure nanotubes with predetermined dimensions in a high yield.
