Abstract
Procedeu de cracare catalitica, folosit pentru cracarea catalitica a hidrocarburilor cu greutate moleculara mare, prin contactarea acestora, la temperaturi ridicate cu un catalizator de cracare, în prezenta unui agent de pasivizare a metalelor cu efect de otravuri pentru catalizator, constînd dintr-un compus de antimoniu cu formula generala: (vezi formula) în care R pot fi identici sau diferiti si reprezinta grupari alchil cu 2...10 atomi de carbon, ca atare substituite cu radicali cicloalchil cu 5...6 atomi de carbon, sau cu radical fenil, caracterizat prin aceea ca agentul de pasivizare se introduce în curentul fluid de hidrocarburi, de preferinta, amestecat cu aceasta într-o cantitate cuprinsa între 0,002 si 5% în greutate si de preferinta între 0,01 si 1,5% în greutate antimoniu, raportat la cantitatea de catalizator, agentul de pasivizare fiind tratat la o temperatura sub temperatura sa de descompunere si anume, sub 260 degree C, înainte de introducerea curentului fluid de hidrocarburi în zona de cracare.
