ABSTRACT:
Aliphatics are aromatized in a two-stage catalytic upgrading process. In the first stage, aliphatic hydrocarbons are at least partially cracked and dehydrogenated to form an intermediate product stream. The extent and selectivity of the cracking and dehydrogenation reactions are preferably controlled to maintain heat balance in a second stage catalytic aromatization step.
In a preferred embodiment, a first aliphatic feedstream is cracked and dehydrogenated to form an intermediate product stream. The intermediate product stream is then mixed with a second aliphatic feedstream and contacted with a zeolite aromatization catalyst. Cracking and dehydrogenation of the first aliphatic feedstream is controlled to provide heat balanced aromatization of the combined streams.
