Abstract. This paper presents the effects of acid treatment on the activity, product selectivity and life span of iron Fischer–Tropsch (FT) catalysts supported on carbon nanotubes (CNTs). Two different types of CNTs with low surface area (25 m2/g) and high surface area (170 m2/g) were prepared and treated with 35 wt% HNO3 at 25 8C and 110 8C for 16 h. Fe/CNTs were prepared using incipie…
Abstract An extensive study of Fischer–Tropsch synthesis (FTS) on carbon nanotubes (CNTs) supported cobalt catalysts with different loadings of cobalt, ruthenium and potassium is reported. Up to 30 wt.% of Co, 1 wt.% of Ru and 0.0066 wt.% of K were added to the catalyst by co-impregnation method. The physicochemical properties, activity and selectivity of the catalysts were assessed.
