Abstract

Investigation of Limonite for catalyst on South Banko coal liquefaction were

carried out under standard condition which has developed by BPPT.

Limonite Soroako is a natural mineral that found at Nickel Mining on

Soroako, South Sulawesi. Four samples of limonite was examined using 5L

autoclave at our coal liquefaction laboratory in order to investigate theis

activities to produce high distillate yield at standard condition (450oC, 9MPa

cold H2). The results showed that limonite SYY-E-MY gave a higher distillate

yield than those of other limonite (difference about 10-30%daf coal or

%bkta). Further investigations were conducted to compare with other

catalysts: synthetic g –FeOOH and pyrite (FeS2). Again, the activity of limonit

S99-E-MY was still superior compared to those of synthetic and pyrite

catalysts. The yield difference was about 10-16%daf coal or %bkta).

Experiment revealed that the factor of FeOOH critically affected the coal

liquefaction reaction to improve the distillate yield and to reduce CLB yield.

Besides, the representative of Co metal in the limonite (≥5-10 %bk) could

give synergism effect with FeOOH to improve the activity of limonite.
