Catalytic Conversion of n-Heptane in Vapour Phase

Abstract

The catalytic conversion of n-heptane in vapour phase was carried out over Zn-Y zeolite and an Egyptian natural aluminosilicate catalysts. The Zn-Y zeolite catalyst was prepared using the sodium form of SK-40 molecular sieve as starting material, by exchanging the sodium ion for Zn by using continuous flow exchange method. The clay catalyst was activated with ZnCl₂ solution. The catalytic reactions were conducted using a conventional fixed bed reactor under atmospheric pressure at space velocity 0.5 hr^-1. The reaction temperature was varied between 300-550ºC. The activities and selectivities of the catalysts in n-heptane conversion were calculated at different reaction temperatures.
