Abstract: Aluminium
sulphate is form
by reacting alumina
which contains in
kaolin with sulphuric acid solution
in a stirred
reactor. Reaction occurs
in variance of
different time and temperature. The
result of reaction
is paste aluminium
which will be
extracted about 3 times using hot aquadest and consentration
of aluminumanalized by titrimetric methode. Time, temperature and
ratio of sulphuric
acid and kaolin in reaction have a lot effect to conversion value result,
while sulphuric acid concentration and speed of agitation are not too effected.
Process condition which is about to be good is temperature 180 oC, reaction time
90 minutes, ratio of sulphuric acid and kaolin
is 3:1, sulphuric acid concentration 65% and speed of agitation 350
rpm. Converted aluminum can reach 82%.
Keywords: Aluminum sulphate, Dry process, Kaolin, Sulphuric
acid, Stirred reactor
