Embodiment Construction

[0046] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0047] Cascade utilization of coal resources is an effective means to improve energy utilization efficiency. Coal pyrolysis can realize the conversion of highly chemically active substances in coal into liquid fuels, coal chemical synthesis feedstock gas and chemicals before combustion or gasification. The application objects of coal pyrolysis include but are not limited to low-rank coal such as lignite and sub-bituminous coal. Taking low-rank coal, which occupies a large proportion in my country's coal resource structure as an example, the classification and quality of low-rank coal can be realized by pyrolysis. Utilization, extraction of high-value products, at the same time, semi-coke produced by pyr...

Abstract

The invention discloses a pyrolysis system and a pyrolysis method.The pyrolysis system comprises a pyrolysis subsystem and a carbon dioxide reduction device, and the pyrolysis subsystem is used for generating carbon dioxide gas and pyrolysis products after raw materials are pyrolyzed; the carbon dioxide reduction device is communicated with the pyrolysis subsystem and is used for generating carbon monoxide from carbon dioxide gas under the action of a carbon dioxide reducing agent.

Description

technical field [0001] The invention relates to the technical field of conversion and utilization of carbon-containing raw materials, in particular to a pyrolysis system and a pyrolysis method. Background technique [0002] Cascade utilization of coal resources is an effective means to improve energy utilization efficiency. Coal pyrolysis can realize the conversion of highly chemically active substances in coal into liquid fuels, coal chemical synthesis feedstock gas and chemicals before combustion or gasification. [0003] In the process of realizing the present invention, it is found that the traditional coal pyrolysis method has the problem of carbon dioxide emission, which restricts the large-scale utilization of pyrolysis. Therefore, it is urgent to develop a pyrolysis technology and system that can realize zero carbon emission. SUMMARY OF THE INVENTION [0004] (1) Technical problems to be solved [0005] In view of this, the present invention provides a pyrolysis s...
