Patent

CA 2664692

A process is described for manufacturing a catalyst composition comprising the steps of (i) precipitating one or more metal compounds from solution using an alkaline precipitant, preferably comprising an alkaline carbonate, optionally in the presence of a thermostabilising material, (ii) ageing the precipitated composition, and (iii) recovering and drying the aged composition, wherein the ageing step is performed using a pulse-flow reactor.

L'invention porte sur un procédé décrivant la fabrication d'une composition de catalyseur, comprenant les étapes consistant à (i) faire précipiter un ou plusieurs composés métalliques à partir d'une solution à l'aide d'un agent de précipitation alcalin, de préférence comprenant un carbonate alcalin, facultativement en présence d'un matériau thermostabilisant, (ii) faire vieillir la composition ayant précipité, et (iii) récupérer puis sécher la composition vieillie, l'étape de vieillissement étant effectuée à l'aide d'un réacteur à écoulement pulsé.
