Claim 8:
9. The apparatus of claim 8, wherein the apparatus further comprises:
A material tank, of which an upper part is communicated with the crusher and a lower part is communicated with the fluidized bed pyrolyzer through a screw feeder, for collecting crushed mineralized refuse, wherein the screw feeder has an installation angle of 4.30°-6.0°, and a ratio of a rotation speed to a limit rotation speed is 0.4-0.6;
A gas-solid cyclone separator in communication with the fluidized bed pyrolyzer, used for gas-solid separation of a light phase obtained after pyrolysis in the fluidized bed pyrolyzer; a quench tower in communication with an upper part of the gas-solid cyclone separator, used for cooling and liquefying a gas discharged from an overflow port of the gas-solid cyclone separator to form an alkane-and-arene precursor biomass oil; and a separation tank in communication with a lower part of the gas-solid cyclone separator, used for collecting residual pyrolyzed carbon;
A heating furnace in communication with a lower part of the separation tank, used for heating the residual pyrolyzed carbon and non-condensable gas sent from a compressor in communication therewith to supply heat to the fluidized bed pyrolyzer in communication therewith, wherein an upper part of the quench tower is communicated with the heating furnace through the compressor, and the quenching tower cools and liquefies the resulting alkane-and-arene precursor biomass oil which is then sent to the boiling bed reactor in communication therewith for hydrogenation reaction;
A hot high-pressure separator and a heating furnace in communication with the boiling bed reactor, wherein the hot high-pressure separator and the heating furnace are communicated with each other; an air cooler in communication with the hot high-pressure separator; a cold high-pressure separator in communication with the air cooler; a compressor in communication with the cold high-pressure separator and the heating furnace; a cold low-pressure separator in communication with the hot high-pressure separator and the cold high-pressure separator; and a heat exchanger in communication with the cold low-pressure separator, wherein the hot high-pressure separator, the cold high-pressure separator and the cold low-pressure separator, are used for separating the hydrocracking product obtained in the boiling bed reactor to obtain arenes and alkanes; and wherein the heating furnace is used for heating circulating oil in the boiling bed reactor;
A heating furnace disposed between the two-stage fixed bed reactors wherein the heat exchanger is communicated with the two-stage fixed bed reactors respectively; an air cooler in communication with the heat exchanger; a cold high-pressure separator in communication with the air cooler; and a cold low-pressure separator in communication with the cold high-pressure separator which is communicated with a heating furnace, wherein the cold high-pressure separator is communicated with the two-stage fixed bed reactors through the heating furnace; and
A heating furnace disposed between the cold low-pressure separator and a rectification tower.
