PERFECTIONNEMENTS AUX APPAREILS DE PRODUCTION DE GAZ D'HUILE.
La présente invention concerne un perfectionnement de l'appareillage décrit dans le brevet principal.
Comme il est décrit dans ce brevet, le cracking cyclique sur catalyseur ou sur empilages réfractaires des hydrocarbures liquides comporte deux phases principales : une phase "fabrication" et une phase "chauffage".
A chaque phase "fabrication" il se produit des dépôts carbonés solides qu'il est nécessaire d'éliminer avant la phase fabrication suivante.
La présente invention a pour but l'élimination plus aisée et avec un meilleur rendement de ces dépôts soit pendant la phase "fabrication" ellemême tout au moins partiellement, soit pendant la phase "chauffage" soit pendant ces deux phases.
L'appareillage comporte un lit de catalyseur approprié placé à l'endroit où se produisent les dépôts carbonés.
L'action du catalyseur s'effectue suivant l'un et/ou l'autre des mécanismes ci-après :
1 / Pendant la phase "fabrication" les fluides gazeux (vapeur en particulier) sont en contact avec les dépôts en présence du catalyseur accélérant la gazéification de ces dépôts par réaction avec ces fluides gazeux.
2 / Pendant la phase "chauffage" l'air surchauffé envoyé pour brûler les dépôts est en contact avec eux en présence du catalyseur accélérant la combustion de ces derniers, ce qui permet d'éliminer les dépôts plus aisément.
<Desc/Clms Page number 2>
Dans le cas du cracking sur catalyseur, ce dernier peut en plus de son rôle pour le cracking, remplir le rôle du catalyseur dont il est question ci-dessus.

IMPROVEMENTS TO OIL GAS PRODUCTION EQUIPMENT.
The present invention relates to an improvement of the apparatus described in the main patent.
As described in this patent, cyclic cracking on a catalyst or on refractory stacks of liquid hydrocarbons comprises two main phases: a “manufacturing” phase and a “heating” phase.
At each "manufacturing" phase, solid carbon deposits are produced which must be removed before the next manufacturing phase.
The object of the present invention is to remove these deposits more easily and with a better yield, either during the "manufacturing" phase itself at least partially, or during the "heating" phase or during these two phases.
The apparatus comprises a bed of suitable catalyst placed at the place where carbonaceous deposits occur.
The action of the catalyst is carried out according to one and / or the other of the following mechanisms:
1 / During the "manufacturing" phase, the gaseous fluids (vapor in particular) are in contact with the deposits in the presence of the catalyst accelerating the gasification of these deposits by reaction with these gaseous fluids.
2 / During the "heating" phase the superheated air sent to burn the deposits is in contact with them in the presence of the catalyst accelerating the combustion of the latter, which makes it possible to remove the deposits more easily.
<Desc / Clms Page number 2>
In the case of catalyst cracking, the latter can, in addition to its role for cracking, fulfill the role of the catalyst referred to above.
