Leaching kinetics of the preparation of raney Fe catalyst for F-T synthesis in slurry phase

摘要

Kinetics of leaching of Raney Fe-Al alloy with alkali has been studied in an agitated reactor by measuring the rate of Al produced during the leaching process at a constant temperature and alkali concentration. The effects of various variables on the initial leaching rate and leaching ratio have been also investigated. These variables are leaching temperature, concentration of alkali, particle size of Raney Fe-Al alloy and stirring speed during the reaction.
