Abstract
The invention relates to a process method for preparing synthesis gas or fuel gas by using waste circuit board resin, and belongs to the field of environmental protection, chemical engineering and gasification. According to the technical scheme, the method comprises the following steps: firstly, recycling a circuit board without electronic components into a factory; crushing the circuit board to acertain particle size by using a crusher; grinding the circuit board to about 200 meshes by using a ball mill, mixing the ground circuit board resin powder with bituminous coal powder to prepare slurry, inputting the slurry into an industrial entrained-flow bed coal water slurry gasification furnace by using a high-pressure slurry pump, and carrying out a series of oxidation-reduction reactions with oxygen and water vapor in the furnace to generate a mixed gas mainly containing carbon monoxide and hydrogen; and after dust removal and purification treatment, using the gas as chemical production synthesis gas for producing synthetic ammonia, urea, acetic acid, methanol, polyol, olefin and LNG, wherein the gas can also be used for process carbon supplementation, hydrogen production and carbon monoxide extraction, and can also be used as industrial or civil fuel gas. Practice proves that the method can turn waste into wealth, is economical and practical, has good economic benefits and environmental protection value, and has a wide application prospect.
Description
Technical field [0001] The invention relates to a process method for preparing synthetic gas or fuel gas from waste circuit board resin, and belongs to the fields of environmental protection, chemical industry and gasification. Background technique [0002] The progress and development of modern science and technology are really changing with each passing day. The applications of various circuit boards are emerging one after another. With the upgrading of products and the expiration of product life, more and more waste circuit boards will be used and the pollution to the social environment will increase. It's getting worse. The production of circuit boards is extremely complicated and contains a variety of materials, but the base materials are mainly epoxy resin, phenolic resin, and glass fiber. These organic resins are mainly carbon, hydrogen, and oxygen compounds, so they have a certain calorific value. [0003] At present, many units and individuals are studying the processing ...
