Isomerization of n-hexane on binder-free shaped platinum-containing mordenite

Abstract

A catalyst has been prepared as binder-free shaped MOR-type zeolite in the H form promoted with 0.5 wt % platinum, and n-hexane conversion over this catalyst has been studied. It has been found that the selectivity for C₄–C₆ isoparaffins on the new catalyst is about 90% at 300°C, a feed space velocity of 1.5 h^–1, and a hydrogen pressure of 3 MPa, with the hexane conversion being 80.0–83.0 wt % and the selectivity for isohexane making 83.0–86.0%. It has been shown that the new catalyst is stable for 50 h on-stream under these conditions.
