Abstract

The "n-hexane and steam" gaseous mixture was first sent through a precatalytic zone containing quartz beads (temperature Tt), and then through a catalyst bed (T-2). The latter contained a ZSM5 zeolite or a zeolite-containinghybrid catalyst. By moderately increasing TI (T-2 being kept constant), significant increases in the total n-hexane conversion and in the total yieldof light olefins were obtained. The ethylene/propylene product ratio couldbe varied widely, for instance, from 1.0 to 2.0 by varying T-1 from 660 to720 degreesC. Such temperature effect of zone I on the overall process performance was explained by the formation of selectivity modifiers such as diolefins. With the hybrid catalyst, the enhanced production of light olefinswas also assigned to the formation of large olefins on the Cr-Al-containing cocatalyst.
