1,3-Butadiene을 포함한 C4 유분의 이량화반응용 촉매의 수명에 관한 연구

Selective hydrogenation of 1,3-butadiene in C_4 raffinate was carried out in fixed bed reactor using Pd/alumina catalysts. Concentration of 1,3-butadiene in C_4 raffinate could be reduced under 100 ppm. The life of dimerization catalyst using C_4 raffinate after selective hydrogenation was longer than that of dimerization catalyst without selective hydrogenation. It was found that dilution of olefin concentration in feed was effective to increase dimerization catalyst life.
