The effect of aerosol-deposited ash components on a cobalt-based Fischer–Tropsch catalyst

Fischer-Tropsch Synthesis – investigation of the deactivation of a Co catalyst by exposure to aerosol particles of potassium salt submitted to Appl.. Effect of fly ash and H2S on

The location of potassium (K) on Cobalt (Co) and its effect on adsorption and adsorption- induced surface restructuring is important for understanding the deactivation

9 Table 1 XPS elemental surface composition of fresh, ex situ reduced (exposed to air) and spent catalyst samples exposed to sulphur during testing. HR-ICP-MS analysis of sulphur

The effect of process parameters on activity and selectivity of the Co- based Fischer-Tropsch catalyst will be described in separate chapters as follows: effect of syngas flow,

The objective of this work is to investigate the effects of process conditions such as H 2 /CO ratio (2.5−1.0), CO conversion level (15 – 75%), added water in the syngas, and

KNO 3 dissolved in deionized water (0.025M) was placed in the pneumatic atomizer (Palas GmbH AGK-2000), which produces aerosol particles from the solution. Nitrogen is used

 Pre-impregnation with chloro or methoxy alkyl silanes leads to silylation of the γ-Al 2 O 3 support, a hydrophobic surface and smaller cobalt crystallites. There are anomalies

Reduction of the material was investigated in terms of the energetics of oxygen removal from the graphene oxide, Al 2 O 3 and the Al-O-C interface bond of the
