Abstract: A decomposition processing apparatus for PCBs prolongs the staying time of the PCBs in a vertical furnace. The apparatus heats and decomposes the PCBs and includes porous staying plates through which the falling PCBs pass, to delay the progress of the PCBs through the apparatus and thus subject the PCBs to sufficient thermolysis.

Abstract: A decomposition processing apparatus 1 for PCB prolongs a staying time of PCB even in a vertical furnace or the like. In the decomposition processing apparatus 1 for PCB which heats and decomposes supplied PCB 2, staying means 3 which has the affinity to PCB 2 is provided so as to guide PCB 2 and obtain a staying time during which PCB 2 is satisfactorily subjected to thermolysis.

Abstract: Devolatilization of sticky polyolefin powder and deactivation of catalyst residue can be carried out efficiently and sufficiently without the need for accompanying facilities commonly used in the treatment of powdery products in an apparatus comprising (a) a horizontal cylindrical body, (b) a stirrer provided with one revolving shaft and a plurality of specified stirring blades (c) an inlet pipe for introducing untreated polyolefin power and heating gas, (d) a variable barrage for controlling the holding amount of polyolefin powder insides of said horizontal cylindrical body, (e) an outlet way for discharging after-treated polyolefin powder and gas, (f) inlet pipes for heating gas having a pipe for feeding an after-treating agent, and (g) indirect heating mean.
