Abstract

1,242,158. Cooling exothermic reactions. FARBWERKE HOECHST A.G. 26 Nov., 1969 [26 Nov., 1968], No. 57935/69. Addition to 1,226,767. Heading B1X. A process for carrying out gas/solid reactions in a fluidised bed comprises passing a gaseous reactant in a downward direction through a loose solid reactant in a reactor, fluidising the solid reactant by intermittently blowing an inert gas into the reactor from below, and withdrawing the waste gas from below the reaction zone during the intervals between the intermittent fluidization blows. The reactant may be as disclosed in Specification 1,226,767.
