一、前言胜利科研所开发的轻油蒸汽转化催化剂Z-402中,加入了人工合成的钾霞石(KAlSiO_4)。这种钾霞石在使用条件下缓慢分解,释放出游离钾碱,从而防止碳在催化剂上的积累。钾霞石的含量直接影响着催化剂的抗积碳性能及催化剂的使用寿命。因此,钾霞石的物相定量是十分有意义的。应用化学分析方法得到的钾含量是催化剂中全部钾碱的总和,应用X-射线衍射法测得的数据是钾霞石的含量,这是化学分析所不能代替的。为此,我们建立了用X-射
I. Introduction Victory Research Institute has developed a light-oil steam reforming catalyst Z-402, adding synthetic kernias (KAlSiO_4). This kernase decomposes slowly under the conditions of use, releasing free potash to prevent the accumulation of carbon on the catalyst. The content of kaliane directly affects the anti-carbon deposition performance of the catalyst and the service life of the catalyst. Therefore, it is very meaningful to quantify the phase of kernia. The potassium content obtained by chemical analysis is the sum of all the potash and alkali in the catalyst. The data obtained by X-ray diffraction method is the content of kernia, which can not be replaced by the chemical analysis. To this end, we set up with X-ray
