Abstract:
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 C. sub. 6 to C. sub. 11 naphthas to produce reformates having a high content of C. sub. 6 to C. sub. 8 light aromatics and a reduced content of heavier C. sub. 9 and C. sub. 10 aromatics.
