摘要： PURPOSE:To obtain efficiently the title hydrocarbon oil with a high arom. hydrocarbon content by performing the pyrolysis of a polyolefin plastic and a specified treatment. CONSTITUTION:The pyrolysis of a polyolefin plastic (e.g. polyethylene) is performed and a generated gaseous product is introduced into a zeolite catalytic layer to be catalytically converted and then guided to the outside of the system, where it is indirectly cooled to be separated into a volatile hydrocarbon gas and a low-b.p. hydrocarobn oil. The temp. of at least a part of the volatile hydrocarbon gas is elevated and is guided together with the pyrolyzed gaseous product into the zeolite catalytic layer to perform catalytic conversion.

摘要： PURPOSE:To efficiently reutilize the subject wastes by melting the wastes of a polyolefinic plastic, transferring the melted product into a melting tank and a thermally decomposing tank at specific temperatures, separating mists from the evaporation products, cooling the residue to separate the residue into a gas fraction and a low boiling point fraction, and subsequently recovering the fractions, respectively. CONSTITUTION:The ground pieces of the wastes of a polyolefinic plastic is fed into a screw type extruder 1, heated, introduced into a melting tank 2, heated at 200-450 deg.C, successively introduced into a thermal decomposition tank 3, pyrolyzed and subsequently separated into the melted product phase of the polyolefin and into the vapor phase of the evaporation product. The evaporation product is passed through a mist-separator 6, and at least one of the separated mists is circulated into the thermal decomposition tank 3. The remaining evaporation product is cooled and separated into a gas fraction and into a low boiling point hydrocarbon fraction. A part or the melted product in the thermal decomposition tank 3 is circulated into a melting tank 2 directly or through a piping 7 after heated, whereby the low boiling point hydrocarbons having high additional values are efficiently produced from the wastes of the plastic to reutilize the wastes of the plastic.

摘要： PURPOSE:To easily obtain a fraction of kerosine and gas oil free of a malodor by thermal cracking or dry distillation of used tire waste, catalytic conversion of the product with a ZSM-5 type zeolite catalyst and fractional distillation of the catalytic conversion product. CONSTITUTION:Used tire waste is finely cut. The cut tire waste 3 is fed into a dry distillation unit 1 or a thermal cracking unit to effect dry distillation or thermal cracking thereof. Subsequently, the product is introduced into a cyclone 4, wherein solid suspended matter including carbon black and sulfur compds. are removed. Subsequently, the product is fed into a catalytic conversion unit 6, wherein it is catalytically converted in a ZSM-5 type zeolite catalyst layer. Subsequently, the catalytic conversion product is fractionally distilled in a heavy oil fractional distillation unit 7 to separate heavy oil 8, followed by fractional distillation in a light oil fractional distillation unit 9 to obtain light oil 10, which is then separated into an oil component and uncondensed gas in a gas/oil separator while discharging the gas out of the system.
