SOLAR HEAT RETRIEVAL UTILIZING ALUMINA INCLUDING CATALYST

摘要

PURPOSE:To permit to separate a reactive substance easily and convert solar light energy into heat energy by setting the catalyst to an active alumina carrier. CONSTITUTION:One example of the catalyst is water-soluble or non-water-soluble polycyclic nitrogen compound having porphyrin skeleton or phthalocyanine skeleton. The carrier is spherical active alumina having principal constituents of drying agent,adsorbing and purifying agent and Al2O3 for carrying the catalyst. The catalyst is dissolved into organic solbent or water, thereafter, the carrier is dipped into the catalyst solution to absorb and set the molecule of the catalyst on the carrier. The method of obtaining a photo-valence isomeride is enough to project light against the heat carrying substance. A high energy heat carrying substance or the photo-valence isomeride obtained by projecting light against the parent heat carrying substance may be converted resersibly to the parent heat carrying substance easily by contacting it with a set-up catalyst made by setting the metallic complex of porphyrin or phthalocyanine.
