<P>PROBLEM TO BE SOLVED: To provide a catalytic cracking furnace capable of more efficiently decomposing waste plastics, and to provide a continuous liquefaction apparatus for waste plastics capable of efficiently, inexpensively and continuously producing fuel oil or the like from waste plastics. <P>SOLUTION: In the catalytic cracking furnace 100, an encapsulated type furnace body 102 is disposed inside an encapsulated type casing 101 while leaving a gap space d, a heating chamber 103 is formed to heat the inside of the furnace body from the periphery of the furnace body by hot air helically passing through the gap space between the inner circumference of the casing and the outer circumference of the furnace body, a decomposition chamber 104, to which a waste plastic raw material P is supplied, is formed in the furnace body, and in the decomposition chamber, a catalyst C for catalytic cracking of the supplied waste plastic raw material P under heating conditions is reserved and in the decomposition chamber, a pair of kneading members 105 for kneading the waste plastic raw material P and the catalyst C is disposed. The liquefaction apparatus includes: the catalytic cracking furnace; a raw material supply means 200 of a waste plastic raw material; a hot air generating furnace 300; a fractional distillation means 400 for achieving the fractional distillation of decomposed gas G generated in the catalytic cracking furnace; an oil reserving means 500 reserving the distilled component; and a regenerating means 600 for the catalyst. <P>COPYRIGHT: (C)2012,JPO&INPIT |
