Embodiment 1

[0083] Example 1: 10,000 tons / day mineralized waste treatment process and device

[0084] In a mineralized waste treatment device with an annual treatment capacity of 10,000 tons / day, a set such as figure 1 The specific operation process and effects of the mineralized waste pyrolysis residue hydrocracking treatment unit shown are as follows:

[0085] Mined and recycled mineralized waste is naturally dried for a proper period of time, and the mineralized waste is crushed by a crusher and collected into a material tank, and then sent to a fluidized bed pyrolyzer for carbonization of organic matter by a screw feeder, and collected after pyrolysis The fixed charcoal and ash fall into the separation tank, and the separated pyrolytic charcoal and the non-condensable gas delivered by the compressor are sent to the heating furnace for combustion, and the combustion heat supplies heat to the fluidized bed pyrolyzer; after pyrolysis, the light phase The components are sent to the gas...

Abstract

The invention relates to a method and a device for hydrocracking mineralized refuse cracked oil and provides the method for hydrocracking the mineralized refuse cracked oil. The method comprises the following steps: (a) breaking and pyrolyzing mineralized refuse to obtain arene and alkane precursor biomass oil; (b) hydrogenizing the arene and alkane precursor biomass oil obtained in the step (a) and separating an obtained hydrocrackate to obtain arene and alkane; and (c) purifying, recovering and optimizing the arene and the alkane obtained in the step (b), and deeply processing to produce naphtha, jet fuel, light diesel oil and heavy diesel oil. The invention further provides the device for hydrocracking the mineralized refuse cracked oil.

Description

technical field [0001] The disclosure belongs to the field of mineralized waste recycling and relates to a method and device for combined treatment of reclaimed mineralized waste by screening, pyrolysis and hydrocracking. Specifically, it relates to a method for realizing oil product recovery by hydrogenation in series with an integrated crusher, a screw feeder, a fluidized bed pyrolyzer, an ebullated bed reactor and a fixed bed reactor, and a device for implementing the method. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, the amount of domestic waste is also rising. According to the "2017 National Annual Report on the Prevention and Control of Solid Waste Pollution in Large and Medium Cities in China" published by the Ministry of Environmental Protection, in 2016, 214 large and medium cities produced 188.505 million tons of domestic waste and disposed of 186.844 million tons, with a disposal rate of 9...
