Isomerization of 1-Butene on Natural Zeolite from Malang, East Java, as Catalyst

Melia Laniwati


The isormerization of 1 -butene with natural zeolite from Malang, East Java, as catalyst was carried out in an isothermal fixed bed reactor. The temperature has been varied from 300 up to 550C. 1-Butene has been prepared by dehydration of n-butanol on alumina active at 400C. The main component of natural zeolite from Malang is mordenite. Natural zeolite is an effective catalyst for the interconversion isomerization of 1-butene, but unfortunately its acidity is not enough for skeletal isomerization. The main product is 2-trans-butene. The 1-butene conversion ranged from 78.8% to 84.5%. At the high temperature (500- 550C), all reactants would be cracked 100%.
