Abstract
The invention relates to a process method for preparing synthesis gas or fuel gas by using waste circuit board resin, belonging to the fields of environmental protection, chemical industry and gasification. The technical solution is first to recycle the circuit boards from which the electronic components have been removed into the factory, crush them to a certain particle size with a pulverizer, and then use a ball mill to grind them to about 200 meshes, and mix the ground circuit board resin powder with bituminous coal powder , to make a slurry, and use a high-pressure slurry pump to input it into an industrial-type entrained-bed coal-water slurry gasifier, and undergo 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. After dedusting and purification, the gas can be used as synthetic gas for chemical production, for the production of synthetic ammonia, urea, acetic acid, methanol, polyols, olefins, LNG, and can also be used for carbon replenishment, hydrogen production, and carbon monoxide extraction. Industrial or residential gas. Practice has proved that the invention can turn waste into wealth, is economical and practical, has good economic benefits and environmental protection value, and has broad application prospects.
Description
technical field [0001] The invention relates to a process method for preparing synthesis gas or fuel gas by using waste circuit board resin, belonging to the fields of environmental protection, chemical industry and gasification. Background technique [0002] The progress and development of modern science and technology is really changing with each passing day. The application of various circuit boards emerges in an endless stream. With the upgrading of products and the expiration of the service life of products, there are more and more waste circuit boards, which will pollute the social environment more and more. It's getting serious. The production of circuit boards is extremely complicated and contains a variety of materials, but its 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 people are studying t...
