A method for manufacturing a hollow structure suitable for example as reservoir for pressurized fluids, which structure is obtained by curving over a part of its length a corrugated tube provided circumferentially in the hollow of its waves with a hardenable fiber reinforced composition, then subjecting the tube thus curved over at least a part of its length to a treatment for hardening the hardenable composition. The tube may comprise longitudinal reinforcements (braid or layers of widely spaced helical wires), the ends of the tube being possibly equipped with systems for communicating with the outside or for sealing, the final shaping being followed by a treatment for hardening said composition. The winding of the tube may be carried out about a central core or drum.

A reaction-distillation method is provided in which a chemical reaction and fractionation are conducted in an apparatus having at least one reaction-distillation zone (A,B) including at least one bed of solid elements disposed on a fluid-permeable support (5) having perforations small enough to retain the elements. The bed of solid elements includes loose solid catalytic particles (2) and at least one receptacle (3), containing at least one distillation packing body (4). The external jacket of the at least one receptacle (3) is permeable to fluids and impermeable to the solid catalytic particles (2) and the packing body (4). The apparatus can be used for carrying out chemical reactions and concomitant fractionation of the reaction mixture, for example, to synthesize ethers from olefins and alcohols.

The invention relates to an alkylation process, in which a charge incorporating at least one isoparaffin and at least one olefin containing 2 to 6 carbon atoms per molecule, is treated in the presence of a solid alkylation catalyst. In the process, catalyst present in a reaction R is contacted with the charge, recycled liquid effluent discharged from reaction zone R and liquid effluent discharged from an isobutane/n-butane/alkylate separation zone S. The process uses a specific catalyst, e.g., sulfuric acid impregnated on a porous support.
