Popis:	This study found that promoted precipitated iron catalysts, containing large quantities of Hematite, demonstrated adequate activity, selectivity, and attrition resistance operating under commercial Fischer–Tropsch synthesis conditions in a product demonstration slurry bed reactor run over an approximately 170-day period. While small quantities of Hematite ( 0.30 cm3/g) and pore size (60–80 A) can be induced if larger quantities of about 30–40 wt % Hematite are present in the fresh calcined unreduced catalyst. The catalyst demonstrated exceptional attrition resistance.
