Title
(EN) TWO-STAGE AUTO THERMAL REFORMING PROCESS AND SYSTEM
(FR) SYSTEME ET PROCEDE DE REFORMAGE THERMIQUE AUTOMATIQUE EN DEUX ETAGES
Abstract
(EN) A process for converting a light hydrocarbon stream into a synthesis gas in a two stage reactor vessel having two active catalyst zones. Light hydrocarbon gas stream (101) previously mixed with steam (102) and heated to a feed temperature between about 750 °F and about 950 °F forms a background fluid (103). A first oxygen-containing gas (104) is heated to temperatures in the range of from 400 to about 1 050°F. The heated first oxygen-containing gas is mixed with the background fluid (103) in the first mixing section (100). The velocity of the mixture is maintained at a high level, at least about 100 feet/second, to assure prompt delivery of the mixture to the surface of the catalyst, which is present in the first reaction section (200). A portion (105) of the oxiding gas (104) is bypassed to the second mixing section (300). The bulk product fluid (302) from the second mixing device (300) is then passed over the catalyst of the second reaction section (400).
(FR) L'invention concerne un procédé de transformation d'un courant d'hydrocarbures légers en un gaz de synthèse dans une cuve de réacteur à deux étages possédant deux zones catalytiques actives. Un courant de gaz d'hydrocarbures légers (101) préalablement mélangé à de la vapeur (102) et porté à une température d'alimentation comprise entre environ 750 °F et environ 950 °F forme un fluide de fond (103). Un premier gaz contenant de l'oxygène (104) est porté à des températures d'alimentation comprises entre 400 et environ 1050 °F. Ce premier gaz chauffé contenant de l'oxygène (104) est mélangé au fluide de fond (103) dans la première partie de mélange (100). La vitesse du mélange est maintenue à un niveau élevé, au moins à environ 100 pieds/seconde, de manière que le mélange soit envoyé rapidement sur la surface du catalyseur présent dans la deuxième partie de réaction (200). Une partie (105) du gaz oxydant (104) est détournée vers la seconde partie de mélange (300). Le produit global fluide (302) provenant du second dispositif de mélange (300) est ensuite envoyé sur le catalyseur de la seconde partie de réaction (400).
