Naphtha reforming catalyst and process

摘要

The invention provides a crystalline type L zeolite reforming catalyst comprising cylindrically shaped crystals having a length of 0.6 microns or less and an average length:diameter ratio of less than about 0.5, the catalyst containing at least one Group VIII metal and from about 0.1 to 2 wt.% halogen, e.g., chlorine. Also provided is a method for activating or regenerating the catalyst wherein a fresh or de-coked catalyst is oxychlorinated, purged to remove excess chlorine and reduced. The catalysts are particularly useful for the reforming of C6 to C11 napththas to produce reformates having a high content of C6 to C8 light aromatics and a reduced content of heavier C9 and C10 aromatics.
