Abstract
Paraffins having a carbon number in excess of 10 are converted to aromatics, such as n-alkylbenzenes, over a dehydrocyclization catalyst comprising a large-pore zeolite containing at least one Group VIII metal. This process is carried out at a pressure of less than 100 psig. The dehydrocyclization catalyst can contain an alkaline earth metal selected from the group consisting of barium, strontium, and calcium. Preferably, the dehydrocyclization catalyst has from 8 to 10 percent by weight barium and from 0.2 to 1.0 percent by weight platinum, and the large-pore zeolite is a type L zeolite.
