Description

Background
The energy structure of China has the characteristics of rich coal, less gas and lean oil, and the energy structure is mainly made of coal. The efficient clean utilization of coal promotes the development of the coal chemical industry, and the coal gasification technology is vigorously developed in recent years as a tap of the coal chemical industry. Coal gasification refers to the process of converting coal into synthesis gas and a small amount of residue by reacting the coal with a gasifying agent to perform various chemical reactions. In 2018, the modern coal chemical industry converts 9560 ten thousand tons of coal altogether, and in the last half of 2019, about 5570 ten thousand tons of coal are converted. With the large-scale popularization of the coal gasification technology, a large amount of gasified slag is generated, and the annual production of gasified slag exceeds 3300 ten thousand tons.
The coal gas slag is generated by incomplete combustion of coal and oxygen or oxygen-enriched air to generate CO and H 2 In the process of (2), inorganic minerals in the coal undergo different physical-chemical transformations along with solid residues formed by residual carbon particles in the coal, and the solid residues can be divided into coarse residues and fine residues. The coarse slag is generated at a slag discharging port of the gasification furnace and accounts for 60% -80%; the fine slag is mainly generated in a dust removing device of the synthesis gas and accounts for 20% -40%. The existing treatment mode of gasified slag mainly comprises stockpiling and landfill, and has not been applied in large-scale industrialization. Along with the large-scale popularization and application of the coal gasification technology, the yield of the gas slag is increased, a large amount of piled gas slag not only pollutes the environment, but also causes the waste of a large amount of land resources, and also causes adverse effects on the sustainable development of various coal chemical enterprises.
The gasification slag is mainly composed of SiO 2 、A1 2 O 3 、MgO、CaO、Fe 2 O 3 And C and other substances, the content of carbon residue in gasified fine slag is higher than that in gasified coarse slag, and in the aspect of recycling, the research on the application of gasified slag at home and abroad is mainly focused on the following aspects: (1) and (3) preparing construction building materials: aggregate, cementing material, wall material, baking-free bricks and the like; (2) soil and method for producing soilAnd (3) water body restoration: soil improvement, water restoration and the like; (3) residual carbon utilization: carbon residue property, carbon residue quality improvement, cyclic blending combustion and the like; (4) preparing a high added value material: catalyst carrier, rubber-plastic filler, ceramic material, silicon-based material, etc. Although the economic benefit is relatively obvious, the problems of high cost, complex flow, difficult regulation and control of impurities, small downstream market and the like are mainly existed in laboratory research or expansion test stage, and the large-scale utilization can not be realized. Meanwhile, due to the characteristics of high carbon content, high impurity content and the like, the problems of low doping amount of construction materials, unstable quality, serious secondary pollution in ecological treatment and the like are caused, and the economic and environmental benefits are poor.
At present, the method mainly adopted by recycling waste gas slags as building material resources comprises two modes of direct utilization, incineration recycling and the like, and Chinese patent document CN106116348A discloses a sunlight greenhouse wall body containing coal gasification slag and a preparation method thereof. The gasified slag has complex components, contains more combustible carbon in the interior, is directly used by reference, has larger influence on the strength and fireproof performance of building materials, has limited application, and is difficult to popularize and apply.
