Abstract

CNT-based COBALT catalysts were made with Ca, Ce, K and Zr PROMOTERs. Then the addition of Ca / Ca and K / Zr was carried out by impregnation method and the SYNERGETIC EFFECT of an alkaline, alkaline earth PROMOTER with a transition metal or lanthanide PROMOTER was investigated. The structural properties of the catalysts were investigated based on technologies such as X-Ray Diffraction (XRD), total surface area measurement and pore size distribution of catalysts (BET), atomic emission (ICP) and Temperature-Programmed Reduction (TPR). The FTS performance of the catalysts was studied in a fixed-bed micro-reactor under conditions of 220 °C, 18bar, and H2/CO = 2 (v/v). The results of the test showed that simultaneously adding Ca-Ce to the Co / CNT catalyst and its SYNERGETIC EFFECT increased the conversion rate of CO by 7%, and also by adding K-Zr PROMOTERs to the Co / CNT catalyst and their SYNERGETIC EFFECT C5 + selectivity increased From 72% to 82%.
