Description
Technical field
The present invention relates to a kind of industrial shaping coal, be specifically related to a kind of multifunctional efficient gas-making type coal and preparation method thereof.
Background technology
The main raw material preparing gas with coal is high-quality anthracite block coal, but anthracite block coal reserves only account for about 1% of coal reserves, and the ratio of lump coal declines, and price constantly rises, and cannot meet the needs of industrial development to lump coal.Coal, except lump coal, also has a large amount of fine coal, due to the raising of coal mining mechanization degree, makes anthracite fine coal account for 60% of hard coal output, if insufficient utilization, have a strong impact on environment and health.
At present, usually can utilize tackiness agent that fine coal is made moulded coal, moulded coal can replace a part to the less demanding lump coal of fire coal, need not change coal-fired operating mode and the equipment of existing various boiler, and can reduce energy cost and topsoil.Tackiness agent conventional is at present inorganics, organism and mixture, these tackiness agents have adapted to the requirement of coal powder formation in certain occasion, have also been obtained certain application, but cold strength is low, calorific value is low shortcoming that the moulded coal that these tackiness agents are made still exists, the needs to the higher enterprise's coal of fire coal requirement can not be met, the limitation of this technology hinders the development and apply of moulded coal, also makes coal-burning utilities coal cost remain high always.
Summary of the invention
An object of the present invention is the above-mentioned shortcoming overcoming prior art, and provide a kind of multifunctional efficient gas-making type coal, the cold strength of this moulded coal is high, and not easily broken, vaporization rate is high, and ash content carbon is low, and captured sulfur result is good, and coal consumption is low.
