Abstract
The invention relates to catalysts and their use in processes for dehydrocyclization of light paraffinic hydrocarbon feedstock to higher-value hydrocarbon, such as aromatic hydrocarbon, to dehydrocyclization catalysts useful in such processes, and to the methods of making such catalysts. One of more of the dehydrocyclization catalysts comprising a crystalline aluminosilicate zeolite having a constraint index of less than or equal to about 12, at least one Group 3 to Group 13 metal of the IUPAC Periodic Table and phosphorous.
