摘要:
Solar reforming of methane has attracted a great attention because this reaction can realize energy storage of high-temperature heat from concentrated solar radiation and optimal utilization of resources of natural gas. Catalytically active absorber has a key role on absorption of solar energy and reforming of methane and becomes focus of solar reforming of methane research. The article introduces that the composition of catalytically active absorber and three types of catalytically active absorbers in terms of their matrix (porous alumina and SiC ceramics, metal foam, ceramic tubular array (nicknamed "porcupine")) combining the developments of reactor/receiver. Applied in directly irradiated solar reactor/receiver (volumetric reactor/receiver), the capability of catalytically active absorbers is mostly depended on the concentrated solar energy flux, matrix element, catalyst support (or washcoat) and active catalyst. According to the domestic and overseas researches, the future research directions and emphasis are analyzed and discussed. The future research should not only exploit the actual application system but also resolve the problem of uniform coating and combining between catalyst support and matrix for the high temperature reaction system. Photocatalytic enhancement of the reaction should also be taken into consideration, which will help to develop the cheap and efficient catalyst system.
