A process is described in which an elastic fluid is contacted with a particulate solid. This comprises providing a substantially vertical elongate tubular containment zone (1) containing a charge of the particulate solid (5), the volume of the containment zone (1) being greater than the settled volume of the particulate solid (5). An upper retainer means (3) is mounted at the upper end of the containment zone (1), the upper retainer means (3) being permeable to the fluid but adapted to retain particulate solid (5) in the containment zone (1). A follower means (4) is movably mounted in the containment zone (1) beneath the charge of particulate solid (5) for movement upwardly from the lower end of the containment zone (1) upon upward flow of elastic fluid through the containment zone (1) at a rate beyond a threshold rate. In the process the elastic fluid is caused to flow upwardly through the containment zone (1) at a rate which is sufficient to cause particulate solid (5) to rise up towards the upper end of the containment zone and form a cushion of particulate solid (5) against the underside of the upper retainer means (3). The is rate is in excess of the threshold rate so as to cause the follower means (4) to move upwardly until it abuts against the underside of the cushion of particulate solid (5). The invention also provides an apparatus suitable for carrying out such a process and a method of loading a particulate solid into a substantially vertical tube.

L'invention concerne un procédé consistant à mettre un fluide élastique en contact avec un solide particulaire. Ledit procédé consiste à mettre en oeuvre une zone de rétention tubulaire allongée essentiellement verticale (1) contenant une charge du solide particulaire (5), le volume de la zone de rétention (1) étant supérieur au volume décanté du solide particulaire (5). Un organe de retenue supérieur (3) est monté sur l'extrémité supérieure de la zone de rétention (1), ledit organe de retenue supérieur (3) étant perméable aux fluides mais pouvant retenir le solide particulaire (5) dans la zone de rétention (1). Un organe suiveur (4) est monté de manière mobile dans la zone de rétention (1) en dessous de la charge de solide particulaire (5) de manière à se déplacer vers le haut de l'extrémité inférieure de la zone de rétention (1) sous l'effet d'un flux ascendant de fluide élastique dans la zone de rétention (1), à une vitesse inférieure à une vitesse seuil. Selon l'invention, ladite vitesse suffit à créer un mouvement ascendant du solide particulaire (5) vers l'extrémité supérieure de la zone de rétention de manière que ledit solide forme un coussinet de solide particulaire (5) sous le côté inférieur de l'organe de rétention supérieur. Ladite vitesse est supérieure à la vitesse seuil de manière que l'organe suiveur (4) se déplace vers le haut jusqu'à buter contre le côté inférieur du coussinet de solide particulaire (5). L'invention concerne également un dispositif destiné à la mise en oeuvre du procédé selon l'invention, et un procédé destiné à alimenter un solide particulaire dans un tube vertical.
