Abstract

Prezenta invenţie se referă la polimerizarea continuă a olefinelor în pat fluidizat gazos, în special a etilenei, propilenei sau amestecurilor acestora cu alte olefine, în care gazul recirculat conţinând monomerul utilizat la fluidizarea patului, este răcit pentru a condensa cel puţin o anumită hidrocarbură lichidă. Lichidul condensat, care poate fi un monomer sau un lichid inert, este separat de gazul derecirculare şi este alimentat direct în pat pentru a produce răcirea prin căldura latentă de vaporizare. Lichidul ce alimentează patul poate fi introdus direct prin duze de atomizare sau prin duze obişnuite. Procedeul asigură o productivitate substanţial îmbunătăţită a polimerizării în pat fluidizat a olefinelor în stare gazoasă.
