Beschreibung
Zusammenfassung:	The present invention relates to a non-metal based metal passivator additive composition and a process for preparing the same. In particular, this invention relates to a non metal based nickel passivator additive composition comprising (i) 60-80% by weight of propylene glycol as a solvent (ii) 20-50% by weight of boric acid. The composition acts as a nickel passivator for FCCU feed stocks. La présente invention concerne une composition d'additif de passivation de métal à base non métallique et son procédé de préparation. En particulier, la présente invention concerne une composition d'additif de passivation de nickel à base non métallique comprenant (i) de 60 à 80 % en poids de propylène glycol en tant que solvant (ii) de 20 à 50 % en poids d'acide borique. La composition agit comme un agent de passivation de nickel pour des charges d'alimentation FCCU.
