By using steady state simulation, the bottleneck of increasing the effic - iency of separation is identified to be the middle sieve tray section with smaller diameter and smaller tray spacing, and the two renovation schemes without any additional invest - ment on equipment are proposed. 4
利用穩態機理模型模擬實際操作過程，找出了限制提高塔的操作負荷以提高操作分離效果的的瓶頸位置，進而提出和比較了在不增加額外設備投資前提下解決這一瓶頸的兩套方案。 -
In cvd support method, carbon nanotubes were prepared with the supported fe catalyst on the regular mesoporous molecular sieve mcm - 41 by catalytic pyrolysis of c2h2. the author studied systematically the effect of different react conditions on the structure, property and thermal - stability of mcm - 41, and reached an optimum condition of prepared mcm - 41, whose mesoporous diameter was about 2. 9nm, with 0. 12 c16tmabr : 1teos : 0. 24naoh : 66. 7h2o under hydro - thermal condition
Cvd基體法制備碳納米管中，首先探索了不同反應條件對mcm - 41材料結構性能和熱穩定性的影響，優化工藝參數，結果發現水熱條件下反應物的摩爾配比為0 . 12c16tmabr ： 1teos ： 0 . 24naoh : 66 . 7h2o時制得的mcm - 41材料最適合用來作為催化劑基體材料，其孔徑大小為2 . 9nm左右。
