REACH.The article considers the composition, properties and main areas of application of modern catalytic systems of the IV and V generations for industrial production of polymers based on propylene. Time dependence of reactor media exchange has been studied at «Tomskneftekhim» for continuous suspension process of polymer synthesis. The authors carried out the comparative experimental-industrial tests of LYNX catalyst modifications for further exchange of the applied brand. In comparable conditions the sets of base polymers were turned out; a complex of comparative investigations in molecular structure and customer quality indices were carried out for them. The authors stated the conclusion on possibility of the exchange of the applied Ti-Mg catalyst by a new modification meeting the requirements of REACH.
Рассмотрены состав, свойства и основные области применения современных каталитических систем IV и V поколений для промышленного производства полимеров на основе пропилена. Для непрерывного суспензионного процесса синтеза полимеров в ООО «Томскнефтехим» исследована временная зависимость обмена реакторных сред. Выполнены сравнительные опытно-промышленные испытания модификаций катализатора LYNX с целью последующей в перспективе замены применяемой марки. В сопоставимых условиях наработаны партии базовых полимеров, для которых выполнен комплекс сравнительных исследований по молекулярной структуре и потребительским показателям качества. Сформулирован вывод о возможности замены применяемого титан-магниевого катализатора на новую модификацию, удовлетворяющую требованиям
