To reuse waste glass fiber-reinforced plastics (GFRPs), porous ceramics (i.e., GFRP/clay ceramics) were produced by mixing crushed GFRP with clay followed by firing the resulting mixture under different conditions. The possibility of using ceramics fired under a reducing atmosphere as adsorbent materials to remove NO and SO from combustion gases of fossil fuels was investigated because of the high porosity, specific surface area, and contents of glass fibers and plastic carbides of the ceramics. NO and SO adsorption tests were conducted on several types of GFRP/clay ceramic samples, and the gas concentration reduction rates were compared to those of a clay ceramic and a volcanic pumice with high NO adsorption. In addition, to clarify the primary factor affecting gas adsorption, adsorption tests were conducted on the glass fibers in the GFRP and GFRP carbides. The reductively fired GFRP/clay ceramics exhibited high adsorption performance for both NO and SO. The primary factor affecting the NO adsorption of the ceramics was the plastic carbide content in the clay structure, while that affecting the SO adsorption of the ceramics was the glass fiber content.
为了再利用废弃的玻璃纤维增强塑料（GFRP），通过将粉碎的GFRP与粘土混合，然后在不同条件下烧制所得混合物，制备了多孔陶瓷（即GFRP/粘土陶瓷）。由于陶瓷具有高孔隙率、比表面积以及玻璃纤维和塑料碳化物的含量，研究了在还原气氛下烧制的陶瓷作为吸附材料从化石燃料燃烧气体中去除NO和SO的可能性。对几种类型的GFRP/粘土陶瓷样品进行了NO和SO吸附试验，并将气体浓度降低率与粘土陶瓷和具有高NO吸附性的火山浮石的气体浓度降低率进行了比较。此外，为了阐明影响气体吸附的主要因素，对GFRP中的玻璃纤维和GFRP碳化物进行了吸附试验。还原烧制的GFRP/粘土陶瓷对NO和SO均表现出高吸附性能。影响陶瓷NO吸附的主要因素是粘土结构中的塑料碳化物含量，而影响陶瓷SO吸附的主要因素是玻璃纤维含量。
