    Abstract: Provided is a process for aromatizing a wide boiling range naphtha feed in order to produce a C8 stream with its C8 aromatics rich in xylene, e.g., preferably containing at least 80 wt.% xylene. The process comprises aromatizing the naphtha feed over a high temperature treated L-zeolite catalyst in the potassium form containing a Group VIII metal, preferably platinum. The high temperature treated catalyst has also been preferably treated at a temperature in the range of from 1025 DEG F to 1275 DEG F while maintaining the water level of the effluent gas below 200 ppmv. A C8 stream with its C8 aromatics being rich in xylene is then recovered from the product stream.

    Abstract: Provied is a process for regenerating a high temperature treated reforming catalyst which has been deactivated due to coke deposition and which catalyst comprises at least one Group VIII metal. The process comprises first burning coke from the catalyst by contacting the catalyst with an oxygen containing gas. The catalyst is then reduced by contacting the catalyst with a reducing gas, preferably hydrogen. The catalyst is then treated at a temperature in the range of from 975 DEG to less than 1150 DEG F. This last treatment step can take place in either a reducing atmosphere, or in an inert gaseous atmosphere. It is also preferred that the last step be conducted while maintaining the water level of the effluent gas below 200 ppmv.
