The porous silicon oxide aerogel composite membrane includes a porous aluminum oxide membrane having a plurality of macro pores with an average diameter larger than 50 nm and a porous silica aerogel membrane formed on at least one side of the porous aluminum oxide membrane and the macro pores of surface layers of the porous aluminum oxide membrane where the porous silica aerogel membrane has a plurality of meso pores with an average diameter of 2˜50 nm and is derived from methyltrimethoxysilane precursor by a sol-gel synthetic method.
Abstract:
Provided are a carbon catalyst for decomposing a hazardous substance that effectively decomposes hazardous substances such as aldehydes, a hazardous-substance-decomposing material, and a method of decomposing a hazardous substance. The carbon catalyst for decomposing a hazardous substance is a carbon catalyst having a catalytic activity for decomposing the hazardous substance. The hazardous substance is, for example, a volatile organic compound such as aldehydes or a malodorous substance such as a sulfur compound. The method of decomposing a hazardous substance, is a method including decomposing the hazardous substance with the carbon catalyst for decomposing a hazardous substance or with a hazardous-substance-decomposing material containing the carbon catalyst for decomposing a hazardous substance.
Abstract:
A method for manufacturing a complex for carbon dioxide separation, the complex for carbon dioxide separation including a support and a carbon dioxide separation layer on the support, and the method including: applying, on the support, a coating liquid for forming the carbon dioxide separation layer including: a water-absorbing polymer, an alkali metal salt, and a filler having a density lower than a density of the alkali metal salt, a new Mohs hardness of 2 or greater, and a volume average particle diameter that is 30% or less of a thickness of the carbon dioxide separation layer; and drying the coating liquid applied for forming the carbon dioxide separation layer to obtain the carbon dioxide separation layer.
Abstract:
Reactor systems are provided that comprise a purification zone comprising an absorbent which comprises silver, an alkali or alkaline earth metal, and a support material having a surface area of more than 20 m2/g, and a reaction zone comprising a catalyst, which reaction zone is positioned downstream from the purification zone.
Abstract:
Provided is an oil deterioration prevention device with which the trapping effect with respect to oil deteriorated components can be improved and with which the oil passage resistance can be reduced, thereby suppressing a rise in pressure loss. This oil deterioration prevention device is equipped with a filter unit equipped with a filter material that filters oil; and a deterioration prevention unit equipped with a powdery deterioration suppressing agent that suppresses oil deterioration. The deterioration prevention unit contains a mesoporous inorganic material, and of the oil fed from an oil storage unit, the oil filtered by the filter unit is fed to parts which are to be lubricated, and the oil in which deterioration has been suppressed by the deterioration prevention unit is returned to the oil storage unit or is fed to the parts to be lubricated.
