There is a linear dependence between the relative intensity I_(9·6)/I_(25·6) of peaks at 2θ on X-ray diffraction pattern of synthesised mordenite and the ratios OH~-/Al_2O_3 and Na+/Al_2O_3 in the hydrothermal system.The intensities affect evidently both adsorption and catalysis properties of products.

The process of nucleation and crystal growth of NaY zeolite is studied with the addition into the hydrothermal system Na_2O/Al_2O_3/SiO_2/H_2O of crystallization directing agent or NaX zeolite as seed crystal over the temperature range 55℃~100℃, and the apparent activation energy for nucleation and crystal growth is calculated. As NaY zeolite can grow at the surface of NaX crystal, the activation energy of nucleation decreases sharply in the presence of NaX zeolite as seed crystal. Alumino-silicate gel is used as crystallization directing agent in the experiments. Changes with aging time of the directing activity of the gel itself and the gel in liquid-phase and solid-phase are examined at 32℃, together with the mechanism of the formation of NaY zeolite in the presence of the crystallization directing agent. The results of experiments show that the directing activity of alumino-silicate gel in liquid-phase excels that of tbe gel itself.

在55℃~100℃的温度区间内,分别研究了在水热体系Na_2O/Al_2O_3/SiO_2/H_2O中加入晶化导向剂及加入NaX型沸石作为晶种,这两种不同的条件下,NaY型沸石的成核及晶体成长过程,并求得了表观成核活化能及表观晶体成长活化能。在32℃时考察了NaY型沸石晶化导向剂及相应的晶化导向剂凝胶液相和凝胶固相的导向活性随老化时间的变化,并对晶化导向剂导向作用机制进行了初步的探讨。实验结果表明,在较长的老化时间内晶化导向剂凝胶液相的导向活性优于晶化导向剂本身。

A four-component model has been adopted and the formulas of carbon isotopic fractionation were re-derived on the basis of Sakai-Ohmoto′s theory. The data of equilibrium constants for reations were also fitted into continuous function of T (K) in hydrothermal system. Then, logfO_2-pH diagrams and calculations were accomplished by TRS-80 computer using a BASIC souce program, thereby the relationship was clearly showed between the carbon isotopic fractionation and the environment parameter (including physical and chemical parameters and source of hydrothermal liquid) under various conditions.

本文按照H. Ohmoto的理论,采用四组份模式,重新推导了热液体系中含碳物质碳同位素组成的计算公式,并将其水溶离子反应平衡常数的离散数值拟合成温度的连续函数。在此基础上,编制了Basic源程序,由计算机完成各种参数的计算及logfO_2-pH图的绘制。从而阐明热液体系中各种条件下,环境(包括物理化学参数和物质来源)对碳同位素组成的影响。
