        Emulsion method consists in carrying out the reaction in a sludge characterized by very small particles of gas and catalyst.  As sludge the high-boiling reaction products are used.  Gas distribution was produced by foam stones with pores of 0.10-0.15 mm. diam.  The catalyst can also be fixed in place by using finely divided metal 1-5 μ particle size in a heavy sludge.  In order to counteract a sinking of the catalyst particles and to conduct away the heat of reaction, the heavy sludge is slowly agitated between the reactor and the cooler so that the heavy emulsion has an opportunity to be degassed at the highest point in the circulation system.  Temperatures of 240°-280° can be used, usually 250°.  Exact conditions and materials to be used are given.
