Experimental study of the deactivation of Ni/AlMCM-41 catalyst in the direct conversion of ethene to propene

In this work, an experimental study of the deactivation and regarding a possible regeneration procedure in the ETP-reaction using Ni/AlMCM-41 (Si/Al = 60) was carried out. ETP experiments at different temperatures and long time on-stream were carried out. Characterization of the catalyst after exper...

ETP experiments at different temperatures and long time on-stream were carried out. Characterization of the catalyst after experiments was performed using powder-XRD, N2-physisorption, NH3-TPD, TPO and TEM.

Regeneration of the catalyst after 30 h on-stream at temperatures lower than 350 ◦C could be performed using a mixture of 5 vol.% oxygen in N2.
