particle size has been evaluated using a novel model in the catalyst deactivation. In this novel method, a new thermodynamically size dependent kinetic equation is used to investigate the crystal growth during the catalyst deactivation. The difference...

The deactivation of cobalt catalyst on the carbon nanotubes (CNTs) as an inert support in Fischer-Tropsch synthesis (FTS) has been modeled assuming a sintering is the dominant mechanism. The mechanism that is correlating ...

Fischer–Tropsch synthesis (FTS) is a process for converting syngas from natural gas or coal to higher hydrocabons. Due to the high FTS and water–gas-shift (WGS) activity, iron-zeolite catalyst is the preferred catalyst for ...

TPSR-H2 and XRD spectra and which were compared with those recorded on conventional co-precipitated iron catalyst. The results reveal that the catalyst deactivation results from the formation of inactive carbide phases and surface carbonaceous species...

A physical mixture of alkali-promoted iron catalyst with binder based on Fischer-Tropsch synthesis and an acidic co-catalyst (HZSM5) for syngas conversion to hydrocarbons was studied in a fixed bed micro reactor. Deactivation ...

Given the competitive effect of water on DME productivity, paraffin formation and catalyst deactivation rate, a steady state investigation of water effect will be insufficient. Besides, temperature plays an important role in catalyst lifetime...
