Title: Polychloroprene prepn. without popcorn formation - by free radical aqueous emulsion polymerisation in specific reactor
IPC: C08F36/18
Filed: 1977-11-02
Abstract: Chloroprene is polymerised in aq. emulsion using free radical initiators and opt. polymerisation inhibitors. Polymerisation is effected in a closed vertical cylindrical reactor having a length/dia. ratio of 2-3.1, with round corners having a smooth surface and free of incorporated parts (e.g. stream breakers). The reactor is surrounded by a heating and cooling jacket and is provided with one or more propeller stirrers having 2-5, pref. 3-4, blades on their axis, the stirrers being inclined at an angle of 0-45 degrees, pref. 5-45 degrees to the vertical. The stirrers opt. rotate periodically right and left and one stirrer is located in the lower third of the reactor enclosure. During polymerisation the reactor is completely full and its contents are mixed with a recycled reaction mixt. amounting to 5-20 pref. 10-15 m3/min/m2 vol. of reactor. Process is pref. effected continuously using a series of reactors. Formation of popcorn is avoided as well as sedimentation of the emulsion. The process can thus be effected without interruption for a long time without intermediate cleaning.

Title: Combined-flow, sliding-bed gasifier for carbonaceous matter - has larger constriction with rotating conical eccentric grate
IPC: C10J3/02
Filed: 1979-05-17
Abstract: The narrowed down cross-section in the reduction zone of a combined-flow, sliding bed gasifier is circular. Its size is determined by the wall of the reactor and by the grate which is eccentric to the axis of the reactor and turns around the axis. The reactor stands vertically and has at its upper end an inlet for the continuous or intermittent delivery of a fuel contg. solid carbon. From the above downwards the reactor has a drying and pyrolysis zone, a combustion zone with a number of inlets for a combustible gas. This zone blends into the redn. zone. Below the constriction, there are an ash collecting and a gas collecting zone with a vent for the gas and means of removing the ash. Used to make possible an increase in the size of the constriction in the reactor without setting up a relatively cold zone which interrupts the operation. The eccentric rotary grate and a circular constriction in the redn. zone make for a much higher throughput of hard coal, brown coal, wood, agricultural waste matter and town's rubbish.
