silica-alumina gel 中文意思是什麼
silica-alumina gel
解釋
硅鋁凝膠-
( 1 ) for the first time, compositing the chemical compounds of alkaline - earth metal with the adsorption material, 13x molecular sieve, silica gel, and activated alumina to gain a series of composite adsorbents with good performance that higher adsorption capacity and lower regeneration temperature and suitable for adsorption refrigeration systems that can be driven by low - grade thermal energy
首次將堿土金屬化合物及其鹽類與傳統吸附材料13x分子篩、硅膠和活性氧化鋁等復合，制取具有較高吸附量和較低再生溫度的適合於以低溫熱能驅動的吸附製冷過程的一系列優良復合吸附劑。分別在自製的吸附製冷、除濕製冷模擬實驗裝置上，測得該系列復合吸附劑與水和乙醇組成的吸附製冷工質對的吸附製冷性能以及除濕製冷性能均優于傳統吸附劑（ 13x ，硅膠和活性炭） 。 -
By using dta, ir and xrd analysis, the result show that : in the gel glass of these two system, the phase change of the zirconia and the alumina are restricted because of the high content of silica which leads to the stabilization of the prepared materials. and the applications of these two materials is introduced briefly. by using absorption spetrum and fluorescence spetra analysis, the result show that : in the gel glass of the nd - doped sio2 - al2o3 gel bulk glass - ceramic, the strongest emmision is at about 1. 06u m, the clustering of nd3 + ion is controlled by the addition of alumina which creates the " cage effect " to nd3 + ion
同時分別對凝膠進行了dta 、 ir 、 xrd分析，結果表明：對於此兩個系統的凝膠玻璃-陶瓷，由於二氧化硅含量較高，使得氧化鋯及氧化鋁的相變受到約束，從而保證所制備材料的穩定化，同時對兩種材料的應用也作了簡單介紹；對摻釹sio _ 2 - al _ 2o _ 3激光玻璃-陶瓷進行了熒光及吸收光譜分析，結果表明：釹鋁共摻雜二氧化硅玻璃的最強發射處於1 . 06 m左右，加入的少量氧化鋁使釹離子產生「籠效應」 ，阻止釹的團聚。 -
The progress of synthesis of silica - alumina catalysts with the range of the pore diameter increases from micropore to mesopore and application of sol - gel method are reviewed
本文綜述了矽鋁催化材料合成方面的最新進展即所合成的催化劑的孔徑從微孔向中孔發展以及利用以溶膠凝膠法?代表的新制備技術。
