Precipitated iron Fischer–Tropsch catalyst manufacturing: impact of Hematite

Abstract

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.
