Passing an alcoholic beverage through a solid substance that has pores whose diameter allows only ethyl alcohol to pass through and fixes said alcohol by adsorption, said solid substance being either a Y-type zeolite or a monolithic-type microporous substance. In the beverage from which alcohol is partially or totally removed, the process makes it possible to retain in their entirety the molecules that are responsible in particular for the color, the aroma, and the taste of wine, and in particular cliousclatine and/or trypotophan.

Process for reducing alcohol levels in alcoholic beverages

A process is provided for starting a catalytic hydrocarbon conversion reaction or using a hydrocarbon conversion catalyst into which a sulfur agent has been incorporated. In an inert atmosphere, the sulfur-impregnated catalyst is treated with dilute hydrogen to prevent excessive temperatures during the exothermic transformation of oxides into sulfides of the active metals of the catalyst.

Process for starting a hydrocarbon conversion by the prior treatment of

The invention relates to a process and apparatus for transport, storage, loading and unloading of catalyst or adsorbent particles utilizing a special container equipped with a fluid-tight valve and which can rock progressively by means of a reverse-lock, escapement-type ratchet.

An ampoule is filled completely. The ampoule, formed from a casing which may be made of plastic, for example, or made of transparent, opaque or coloured glass, is closed after is has been filled by a frustoconical transverse closure device. The casing of the closure device has a wall provided with an expansion compensator, if the elastic properties of the material used to make this latter are inadequate for complete filling. Filling orifices are provided with a conical raised portion on the outside. Disposed inside the container are hollow spheres which permit the effects of liquid expansion to be compensated for, if necessary, and which are used to make the liquid homogeneous. Caps protect the filling orifices.

Ampoule which is to be filled completely and a syringe for use in

For the impregnation into the pores of a hydrocarbon treatment catalyst of a sulfurizing agent chosen from element sulfur and organic polysulfides with the aid of a solvent, the impregnation process totally or partially comprises a constituent of the olefin or olefin fraction type, e.g., of the vegetable oil type, or a similar constituent. The use of such a constituent makes it possible to significantly reduce the exothermal effect which occurs during presulfurization, compared with the exothermal effects obtained without using such a constituent.

A solid mass for the recovery of mercury, comprising a solid mineral support or dispersant, essentially copper and sulphur at least partly in the form of copper sulfide is produced by the following stages:

The invention relates to a process making it possible when a refining catalyst is subject preferably in situ to the conventional activation reaction in the presence of hydrogen (generally at above 100.degree. C.) to carry out, as a result of the in situ presence of hydrogen, the sulphurization at the required stoichiometric or non-stoichiometric level of the active metal or metals in the composition of the catalyst. In the absence of hydrogen, the process consists of incorporating into the porosity of the new or regenerated catalyst at least one sulphurizing agent of general formula:

The invention concerns a process and an apparatus for separating powdery materials shaped as balls or pellets. It is characterized by the use of a vibrating screw elevator (4) subjected to vibrations of an amplitude so selected as to produce on the screw turns (5), an upward flow of the particles to be removed, while maintaining a downward flow of the particles to be recovered. The invention provides in particular for the separation of round balls from broken balls.

The invention involves a process comprising regenerating a catalyst comprising (a) a support containing at least one oxide of a metal or metalloid and (b) at least one active metal, said process comprising in a first stage treating said catalyst in the absence of hydrogen with at least one sulfurizing agent comprising a polysulfide of the formula

Process of presulfurizing and controlling the activity of catalyst for

The invention relates to a process for the separation of granulate materials, in extruded form of different lengths and of the same or different diameter. It is characterized by the use of a helicoidal vibrating elevator subjected to vibrations whose amplitude is chosen so as to cause on the threads of the spiral on the one hand the ascending flow of all the particles and on the other hand the recovery of the finest particles on the outer edge of the upper thread of the spiral and the largest particles on the inner edge of the upper thread of this spiral.
