The catalytic behaviour of ZSM-5 zeolite can be modified by both physical and chemical methods. Structural parameters of three-dimensional channel of ZSM-5 zeolite can be changed by physical method because of its structural flexibility, so the result is that its catalytic behaviour is also changed.

The catalytic behaviour of ZSM-5 zeolite can be modified by both physical and chemical methods. Structural parameters of three-dimensional channel of ZSM-5 zeolite can be changed by physical method because of its structural flexibility, so the result is that its catalytic behaviour is also changed. To elucidate the mechanism of the chemical modification, the structure of ZSM-5 zeolite after being exchanged with pressurized nickel was determined by polycrystal X-ray diffraction. It has been discovered that there are two positions of bivalent nickel ion outside the framework of ZSM-5 zeolite. One is that Ni2+(1) is located nearby the central point of the median line in the hexacycle facing the cavity of two channels and deviates to ca. 1.5A from the wall of the channel. Ni2+(1) in such position has a direct influence upon the nearby electric charge distribution in the active centre of ZSM-5 zeolite even though it is not inside the channel. Another is that Ni2+(2) is located in parallel to (100) direction of "Z" fqrm channel and deviates to ca. 1.6A from the centre of decacycle. The existence of Ni2+(2), for one thing, changes the effective gap in the opening of "z" form channel; and for another, Ni2+(2) itself can be in contact with the reactants entered . into the channel of zeolite and participates catalysis.

用多晶X射线衍射法测定了经加压交换镍后的ZSM-5分子筛的结构,发现Ni~(2+)在ZSM-5骨架外有两种位置。Ni~(2+)(1)位于面向两个通道交叉处的空腔的六元环中心线的中点附近,偏离通道壁约1.5(?)。它不在通道中,但它可直接影响ZSM-5活性中心附近的电荷分布,从而影响ZSM-5的催化性能。Ni~(2+)(2)位于平行于[100]方向的“Z”字形通道中,偏离十元环中心约1.6(?)。Na~(2+0(2)的存在改变了“Z”字形通道开口的有效空隙,同时Ni~(2+)(2)本身也可能与进入分子筛通道的反应物接触,参与催化作用。

The problem of improving structural flexibility of heat exchanger networks is to retrofit the configuration of a heat exchanger network whose flexibility does not meet the requirement and enhance its flexibility, so as to decrease its energy consumption caused by uncertain parameters. In this paper the key variables for controlling flexibility of a heat exchanger network are identified by a flexibility analysis method. The worst operation point is established in the range of the uncertain parameters. Then two subproblems of temperature difference key variable and heat load key variable are solved to configure the corresponding e-quivalent structure, and the flexibility of the network can be efficiently improved, by using the strategies of shifting, splitting and decreasing heat load.
