▎ 摘  要

NOVELTY - Waste plastic hydrothermal coupling cascade catalytic system comprises a hydrothermal batch processing device (1), an in-situ catalytic pyrolysis device (3), a catalyst regeneration recycling device (5), a non-in-situ catalytic pyrolysis device (10) and a product collecting and utilizing device. The hydrothermal batch processing device comprises a material inlet (2), a material outlet and a circulating water outlet. The hydrothermal batch processing device further comprises a high temperature bearing reaction kettle body and a ribbon type stirrer the material enters the hydro-thermal batch processing device through the material inlet. The in-situ catalytic pyrolysis device comprises a feeding port, a catalyst inlet a, a pyrolysis fraction outlet and a catalyst outlet a. The feeding port is connected with the material outlet of the hydrothermal batch processing device. USE - The waste plastic hydrothermal coupling cascade catalytic system is used for preparation of monocyclic aromatic hydrocarbon. ADVANTAGE - The system solves the problem that the traditional catalytic pyrolysis method product yield is low, pollutant removes difficult technical problem and improves the energy utilization rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for: a method for preparing monocyclic aromatic hydrocarbon by using waste plastic hydro-thermal coupling cascade catalytic. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the waste plastic hydrothermal coupling cascade catalytic system used for preparation of monocyclic aromatic hydrocarbon. 1Hydrothermal batch processing device 2Material inlet 3In-situ catalytic pyrolysis device 5Catalyst regeneration recycling device 10Non-in-situ catalytic pyrolysis device
