| titleOfInvention | The preparation method of propylene |
| abstract | The present invention relates to a kind of preparation method of propylene, mainly solve circulating hydrogen purity in prior art low cause dehydrogenating propane to react Propylene Selectivity is low, catalyst regeneration cycle is short, facility investment simultaneously and the high problem of energy consumption.It is 0.5 ~ 1.5MPa at pressure that the present invention adopts dehydrogenating propane reactant gases, temperature is carry out gas-liquid separation under 0 ~ 45 DEG C of condition, gas phase after separation contains hydrogen and the hydro carbons such as propane, propylene, this gas phase is through adopting the pressure-swing absorption apparatus of at least one sorbent material, be separated the high-purity hydrogen obtained, part Returning reacting system, other hydrogen deliver to technical scheme out-of-bounds, solve this problem preferably, can be used for the industrial production of preparing propylene by dehydrogenating propane. |
