The invention relates to a process for production of propylene from a C4/C5 olefin cut (for example from steam cracking and/or catalytic cracking), this process comprising an optional selective hydrogenation, a selective oligomerization of the isobutenes and an oligocracking of the n-butenes. The invention makes it possible to obtain a high conversion rate with a good propylene yield and to maximize the production of good-quality gasoline.

Process of direct conversion of a charge comprising olefins with four and/or five carbon atoms, for the production of propylene with co-production of gasoline

An enhanced method of producing ethers from iso-olefins and alcohols comprises at least one stage of separation of the excess alcohol by an ionic liquid. The ether-hydrocarbon-alcohol effluent treated in said separation stage by the ionic liquid comes from the reaction section and/or from a fractionating column. The separated and condensed alcohol is recycled in the process.

Ether production method involving alcohol separation by an ionic liquid

The invention concerns a process for preparing a hybrid organic-inorganic material (HOIM) with phosphorus-containing bridges between the surface of an inorganic substrate containing an element M and one or more organic groups of the covalent M-O-P-R type, said process using, as a precursor for said organic group or groups, at least one organophosphorus acid halide with formula RP(O)Xin which x=1 or 2, y=3&#x2212;x, X being a halogen and R designating at least one organic alkyl, aryl or aryl-alkyl group. Non-exhaustive applications for the hybrid organic-inorganic material obtained by the process of the invention are in the fields of anti-corrosion, lubrication, microelectronics, nanotechnologies, composite materials, heterogeneous catalysis, supported catalysis, depollution and biomedical applications.

An enhanced ether production process from an olefinic cut containing at least one iso-olefin and from an alcohol comprises a stage of removal of the acetonitrile present in the hydrocarbon feed by liquid-liquid extraction, the extraction solvent being a non-aqueous ionic liquid of general formula QA, wherein Qis an ammonium, phosphonium and/or sulfonium cation, and Aan anion likely to form a liquid salt with said cation. Advantageously, the method according to the invention generally allows the amount of water at the etherification reactor inlet to be divided by at least two and thus the purity of the ether produced to be improved.

Process for desulfurization of an effluent for cracking or steam-cracking hydrocarbons, more particularly a gasoline for example for catalytic cracking that comprises the elimination of thiophenic compounds by alkylation of these compounds, followed by a distillation, a hydrocracking of said alkyl-thiophenic compounds, then a hydrodesulfurization of the effluent that is obtained from the hydrocracking zone. In a preferred embodiment, this process comprises a preliminary stage for separating the cracking or steam-cracking effluent into three fractions, and proposes sending to the alkylation stage only the intermediate fraction that is low in heavy basic nitrogen-containing compounds that are initially present in the effluents that are to be alkylated.
