Abstract

Методът ще се използва в химическата промишленост. Той може да се реализира в заводски условия, а катализаторът има голяма издържливост. По метода пълнеж от въглеводородна смес се прекарва преди олигомеризирането през молекулярно сито с диаметър на порите, по-голям от 4 ангстръома, до 15 ангстръома. С него могат да се получат олефинови олигомеризати с 4 до 16 въглеродни атома. 10 претенции
