Title: Fischer-tropsch slurry phase process variations to understand wax formation: Quarterly report for period July 1, 1988 to September 30, 1988

Technical Report ·
OSTI ID:6898537

A precipitated iron catalyst without any alkali promoters was studied for 2000 hours on stream in a slurry reactor. Reaction conditions were 230 to 260/degree/C (mostly 260/degree/C), 0.77 to 1.92 MPa, H/sub 2//CO feed ratios of 0.5 to 2.0 and CO + H/sub 2/ conversions of 10% to 65%. A Schulz-Flory carbon number distribution with two chain growth probabilities was required to describe the product. Effects of operating variables on 1-butene/n-butane ratio, methane and oxygenate selectivities, and ..cap alpha../sub 1/ and ..cap alpha../sub 2/ are reported. Kinetic models for secondary reactions of 1-alkenes were developed. Addition of potassium t-butoxide to the reactor substantially shifted both distributions to heavier products. 19 refs., 17 figs., 4 tabs.
