چکیده

The structure-activity relations in the alumina-supported cobalt catalysts are studied at the realistic conditions of Fischer-Tropsch synthesis using in situ time-resolved XRD and catalytic measurements. Cobalt sintering during the first 3-5 h of the reaction and cobalt carbidisation at a longer time on stream (>8 h) coincide with catalyst deactivation.

Solvent Pre-treated Effects of Carbon Nanotube-supported Cobalt Catalysts on Activity and Selectivity of Fischer-Tropsch Synthesis

In this study, the effect of preparation technique of carbon nanotube (CNT)-supported cobalt catalysts on the activity and selectivity of Fischer-Tropsch synthesis (FTS) was studied. Different concentrations of acetic acid were used for the pretreatment of the catalyst support to modify the surface properties of CNT. This modification improved the reduction degree and dispersion of supported co...
