| 摘要 |
The invention describes an energy-efficient method for cogeneration of carbon fibres and electricity by means of bundled sunlight for CO2-neutral manufacture of building materials having compressive and tensile stability. The energy efficiency comes from the principle of using bundled sunlight for directly heating the carbon fibres to be produced, this being made possible by the original PAN fibre, during oxidation and pyrolysis, turning dark and ultimately becoming the almost ideal black body. The heat produced is used, later or simultaneously to the production of fibre material, for producing electricity, in accordance with the classic combined heat and power concept, so as to boost the efficiency, already heightened by this process, of carbon fibre production and to supply energy in the high-value form of electricity. |
