无机纤维是催化剂载体的新材料之一,它具有与通常的粒状载体不同的表面结构和传递性质。本文综述了纤维载体,包括碳纤维、玻璃纤维和氧化铝纤维以及由此制备的催化剂的发展概况。因为纤维催化剂比粒状催化剂的外表面积大得多,而直径却小得多,因而予计对扩散控制的快速表面反应是有利的。此类反应的试验鳍果证明了这个予测。此外,试验表明,纤维材料的结构特征是具有较大比例的微孔和特殊的吸附性质。 Inorganic fibers are one of the new materials for catalyst supports, which have different surface structures and transfer properties than conventional granular supports. This article reviews the development of fiber supports, including carbon fibers, glass fibers, and alumina fibers, and the catalysts prepared from them. Because the fiber catalyst is much larger than the external surface area of ​​the particulate catalyst and the diameter is much smaller, it is presumed to be advantageous for diffusion-controlled rapid surface reactions. The test fin of such reaction proves this prediction. In addition, experiments show that the structural characteristics of the fiber material is a large proportion of micropores and special adsorption properties.
