Abstract
Carbonylation of nickel and selectively reduced laterite ore
Highlights
Carbonylation of nickel obtained by reduction of nickel oxide and selectively reduced Australian laterite ore was studied at temperatures of 80-100°C and CO gauge pressures of 0–56 atm
The results show that the extent of nickel carbonylation increased with increasing temperature from 80 to 100°C at constant CO pressure
The extent of carbonylation of nickel from the selectively reduced laterite ore with particle size 53-200 μm at 100°C and CO gauge pressure 41 atm. was below 50%
Summary
Carbonylation of nickel obtained by reduction of nickel oxide and selectively reduced Australian laterite ore was studied at temperatures of 80-100°C and CO gauge pressures of 0–56 atm. The time for complete carbonylation of nickel was reduced from 5.5 hours in the noncatalytic reaction to 2 hours in the catalytic carbonylation at 100°C and CO gauge pressure 14 atm. The extent of carbonylation of nickel from the selectively reduced laterite ore with particle size 53-200 μm at 100°C and CO gauge pressure 41 atm.
