Abstract
Steam dehydrocyclization of paraffinic hydrocarbons to aromatic hydrocarbons is effected in the presence of supported catalyst, typically bearing rhodium and preferably chromium and potassium, and characterized by a pH less than about 8.
Claims19
The process for steam dehydrocyclizing a steam dehydrocyclizable hydrocarbon which comprises contacting said dehydrocyclizable hydrocarbon and steam at steam dehydrocyclization conditions with a catalyst composition, having a pH of less than about 8 , containing a porous support bearing a catalytic amount of rhodium.
The process for steam dehydrocyclizing a steam dehydrocyclizable aliphatic hydrocarbon which comprises contacting said dehydrocyclizable aliphatic hydrocarbon and steam, in mole ratio of 1-50 steam:
- 1 hydrocarbon, with a catalyst, having a pH of 4.2-7.4, containing a porous support bearing 0.1 w%-2.0 w% rhodium, 1 w%-4 w% potassium, 0.5 w%-20 w% iron, 10 w%-38 w% chromium, and 38 w%-88 w% alumina.
