Enhanced production of aromatics from propane with a temperature-shifting two-stage fluidized bed reactor

Abstract

High-yield production of aromatics from propane with a temperature shifting, two-stage fluidized bed reactor technology.

Enhanced aromatics selectivity and stability in a coaromatization reaction over P/[ZnCr]/HZSM-5

“…13–16 The lower propane selectivity might also be due to the inhibition of the hydrogen transfer of propylene at higher temperatures. 17–22 It is worth pointing out that the enhanced cracking of polymethylbenzene and aromatization of hydrocarbons at higher temperature provided more aromatics. The selectivity to BTEX reached 78% at 610 °C.…”

“…This is ascribed to two aspects: one is the enhancement of aromatization of methanol and n -hexane, and the other is the dealkylation reaction of polymethylbenzene and xylene to benzene and toluene, indicating that higher temperature is beneficial to the generation of monocyclic benzene and toluene and inhibits the further methylation reaction against the generation of xylene. 22…”
