不同活性炭陶瓷的吸附特性研究
Absorption Properties of Different Activated Carbon Ceramics
摘要
Abstract
Activated carbon ceramics were prepared by using diatomite and three different types of activated carbon powder as main materials followed by shaping and calcining processes. The formaldehyde absorption properties, bending strength, bulk density and porosity under different conditions were discussed. The iodine value, SEM, and BET techniques were used to investigate the microstructures and properties of ceramic materials. Results showed that activated ceramic materials exhibited excellent comprehensive properties when used 70% diatomite and 30% coconut shell activated carbon powder as carbon source and calcined at 800℃, as confirmed by the high specific surface area (290.72 m2/g ) , iodine value (352. 14 mg/g) and carbon content (25.46% ). Its formaldehyde absorption was up to 8. 3% at 30 ℃ for 24 h.关键词
