A mixer apparatus accordant with the invention includes a closed reactor (20); two mixers at different heights (28, 29), which are on the same shaft (27), a gas feed pipe (30) below the lower mixer and baffles. The blades of the mixers are mostly rectangular in shape and a minimum of six in number. The angle of inclination of the blades of the lower mixer is around 50-70~ and that of the upper mixer around 25-35~. The number of baffles (23) is at least six and their range around 20% of the reactor diameter. The invention also concerns a corresponding method.
