    Abstract: A continuous process for the successive treatment of finely divided solid materials which are fluidizable at low gas velocities wherein at least two different gases or gas mixtures are utilized and wherein the fluidized bed is held at a constant level in a countercurrent system. The individual gaseous treating materials are conveyed to the different zones of the treatment reactor whereby the cross-section in each zone is chosen so that an essentially constant linear stream velocity of the gas over the total length of treatment is attained whereby the length of the individual successive zones is determined so that in each zone the desired treatment process which is intended to be carried out runs through its desired course.

    Abstract: Carbon black is produced in a flow reaction by spraying a hydrocarbon containing liquid feedstock with the aid of a propellant gas into a stream of hot reaction gases produced by burning a fuel, the feedstock-propellant gas-jet enters the reaction zone with a spraying angle that is greater than the spreading angle of a free jet. There is also described an apparatus for carrying out the process which comprises a binary injector supporting an atomizing nozzle whose head has several channels which are adjusted from zero degrees to different angles to the longitudinal axis of the nozzle.
