    • PURPOSE: A fibrous phase immersing catalyst mat is provided to have an excellent catalyst activation, stability and burning efficiency and to reduce the cost. CONSTITUTION: The fibrous immersing catalyst mat manufacturing method has the steps of: impregnating platinum sodium that is a main catalyst into a silica or alumina unwoven mat carrier less than 0.0001% by melting in ion exchanging water; impregnating Cr2O3 and CoO into the carrier by 1:2 of ratio; calcining the impregnated thing in a dry and anoxic atmosphere, to heighten the stability of a catalyst; and immersing Ce into the silica or alumina unwoven mat, to lower the initial temperature of the catalyst mat. Using this catalyst mat, hydrocarbon fuel saving typed heater can be manufactured.
    • 目的:提供一种纤维相浸渍催化剂垫,具有优异的催化剂活化性,稳定性和燃烧效率,降低成本。 构成:纤维状浸渍催化剂垫制造方法具有以下步骤:通过在离子交换水中熔融将主要催化剂的铂钠浸入小于0.0001%的二氧化硅或氧化铝无纺布垫载体中; 将Cr2O3和CoO以1:2的比例浸渍到载体中; 在干燥和无氧气氛中煅烧浸渍物,以提高催化剂的稳定性; 并将Ce浸入二氧化硅或氧化铝无纺布垫中,以降低催化剂垫的初始温度。 使用这种催化剂垫,可以制造节省碳氢燃料的加热器。

    • A near azeotropic refrigerant mixtures and a refrigeration system using the same are provided to use the refrigerating system steadily without the composition change. A near azeotropic refrigerant mixtures comprises quaternary refrigerant mixtures and additive. The quaternary refrigerant mixtures is made from 1,1,1,2-tetra trifluoro ethane(R134a), penta fluoro ethane(R125), difluoro methane(R32) and propylene(R1270). The additive is the diethyl silicon oil. The weight fractions of the 1,1,1,2-tetra trifluoro ethane: penta fluoro ethane: difluoro methane: propylene is 0.1~99.8: 0.1~99.8: 0.1~99.8: 0.1~99.8. The diethyl silicon oil is added as additive with 0.1~99.8 parts by weight%.
