A cylindrical wall for filtering solid particles in a fluid is disclosed herein, through which a fluid is likely to circulate. This wall includes at least one perforated plate having a finite radius of curvature, and at least one grating element superposed on this perforated plate. The grating element includes a plurality of rigid wires extending in a longitudinal direction and positioned adjacent to one another in order to filter the solid particles, characterized in that the grating element is arranged for the wires to be secured to one another only by means of links between adjacent wires, each link between two adjacent wires occupying only a portion of the length of the wires, and having a thickness less than or equal to the thickness of these wires in proximity to this link.

Cylindrical wall for filtering solid particles in a fluid

A cylindrical wall () for filtering solid particles in a fluid, through which this fluid is likely to circulate, this wall comprising:

A distributor tray for a gas and a liquid circulating as a co-current, said tray comprising a plate perforated by orifices and supporting hollow chimneys extending perpendicularly to said plate, each orifice of the plate being surmounted by a chimney of identical cross section to said orifice, characterized in that the plate is equipped with a plurality of openings arranged on the periphery of each chimney inside a circumscribed circle, the center of which coincides with the center of the chimney, and the radius of which is less than or equal to &#x2153; of the shortest distance separating two adjacent chimneys, and in that a single deflector element is arranged beneath each chimney, the openings and the deflector element associated with each of the chimneys being so arranged as to impart a rotating movement to the gas/liquid mixture under each chimney.

Tray for dispensing a gas and a liquid, reactor provided with such a tray, and use of said tray

The invention concerns an inner tray, arranged inside a chamber, comprising a plurality of parallel beams (), located in a common horizontal plane and fixed through their ends to the wall of the chamber, and, between said beams and supported thereby, rows of adjacent rectangular plates (), completely covering the space between the beams. The invention is characterized in that the supporting edges () of the plates () through which the latter are supported on the beams (), are folded downwards by two substantially right-angled folds, and in that each of the edges () of the plates (), perpendicular to the beams () is folded so as to form a female part () or a male part () capable of being respectively nested in a male () or female () part formed by the folded edge of the adjacent plate. The invention also concerns a chamber containing such a tray.

Inner tray for a chamber

The invention concerns a device wherein the diffusion chamber () comprises, between its upstream end and its downstream end, in the direction of the fluid flow, at least an insert () formed by an annular ring having an external diameter identical to the internal diameter of the chamber, said annular ring being arranged perpendicular to the axis of the supply conduit and projecting towards the inside part of the chamber from the side wall(s) thereof, to form a lateral obstacle to the fluid flow, the solid surface of the insert () being sufficient to generate in the upstream part of the chamber a pressure higher than that of the downstream part.

Device for homogeneous distribution of a fluid in a chamber and uses thereof

A method for the isomerization of a hydrocarbonic charge containing a substantial quantity of paraffin base hydrocarbons with 5 or 6 carbon atoms and a benzene content that is greater than or equal to 2% by weight, in which the charge to be treated passes, in the presence of hydrogen, at a total pressure greater than or equal to 10.10Pa (10 bars) and at an average temperature ranging between 100 and 200&#xb0; C., through at least one reactor () containing a catalyst. An adjunctive fluid is introduced in the upstream section of the reaction zone; a fluid that at 40&#xb0; C. and under atmospheric pressure (1.0134.10Pa), is in a gaseous phase and has a density that is less than or equal to that of the normal-pentane taken into account under the same conditions.

Method for drying the charge from a unit that treats petroleum cuts with a low water charge

A procedure for the alkylation of isobutane by olefinic hydrocarbons, in which a first hydrocarbon charge ( ) rich in isobutane is put in contact with a second hydrocarbon charge rich in light olefins ( ), under conditions that will provoke the alkylation of the isobutane by the light olefins, the effluents that emanate from the reaction area in a fractionation column ( ) are treated in order to extract therefrom at least a first cut rich in alkylate ( ), a second cut rich in normal butane ( ) and a third cut rich in isobutane ( ), said third cut ( ) is then recycled at the entry of the alkylation reaction area. The second cut ( ) rich in normal butane is purified ( ) so as to lower its content in compounds with 5 or more carbon atoms to a value that is less than or equal to 5% by weight, the cut thus purified ( ) is treated in an isomerization reactor ( ) of normal butane to isobutane, this cut is then recycled ( ) at the entry of the alkylation effluents fractionation column ( ).

Procedure and device for the alkylation of isobutane by light olefins

The invention relates to an acid catalyst containing a substantial quantity of supported or mass sulfated zirconia and at least one hydrogenating transition metal. This catalyst is characterized by the fact that the sulfated zirconia is in crystallized form and that it shows a specific surface area greater than or equal to 135 m /g, a pore volume greater than or equal to 0.16 cm /g and an average pore diameter greater than or equal to 20 Angstroms (20&times;10 m). The invention also relates to methods of making this catalyst and to the uses of this catalyst in hydrocarbon transformation chemical reactions requiring the use of an acid type catalyst, such as for example, isomerization, alkylation, oligomerization reactions or even light hydrocarbon dehydration reactions, and also heavier hydrocarbon hydrocracking and hydroisomerization reactions.
