Activity and selectivity of iron Fischer-Tropsch catalysts in a stirred tank slurry reactor

摘要

Four catalysts prepared by two catalyst manufacturers (UCI and Ruhrchemie) were tested in a stirred tank slurry reactor to determine their performance during Fischer-Tropsch synthesis. Precipitated iron was used as the active metal, and Cu, K and SiO_2 were used as promoters. The amounts of promoters (in parts per weight per 100 parts of iron) in these four catalysts were as follows: SiO_2=4.1-25; K=1.1-8.7 and Cu=1.4-7.5. Total BET surface area varied between 136 and 290 m~2/g.
