Preparation of Co/SiO2 Using Several Glycols for Enhanced Fischer-Tropsch Synthesis Activity and Dispersion of Co0 Nanoparticles with Unique Co0 Particle Size Effect

Co/SiO 2 catalysts with highly dispersed Co 0 and reducible Co were prepared by impregnation using an aqueous solution of Co nitrate containing ethylene glycol or its homologs. Addition of glycols enhanced FTS activity by a factor of 4. Particle size of Co 0 decreased from 30 to below 6 nm, while TO...

Description
Summary:Co/SiO 2 catalysts with highly dispersed Co 0 and reducible Co were prepared by impregnation using an aqueous solution of Co nitrate containing ethylene glycol or its homologs. Addition of glycols enhanced FTS activity by a factor of 4. Particle size of Co 0 decreased from 30 to below 6 nm, while TOF of the catalysts was independent of the Co 0 particle size.
