Problems solved by technology

In cases where the reaction products are excessive and / or too complex, traditional catalyst screening methods often fail to isolate the target reaction product in a reasonable time
Thus making these methods unsuitable for relatively rapid screening of large numbers of catalyst samples

Embodiment Construction

[0014] One aspect involved in the present invention is to provide a method for screening catalyst samples, which is to carry out a predetermined chemical reaction process using the catalyst sample to be tested, wherein among the raw materials used in the predetermined chemical reaction process, there is at least one raw material injection The method is the pulse injection method. And the products of the predetermined chemical reaction process include at least one large molecular weight product, whose molecular weight is greater than that of any raw material and other products used. At the same time, in the process of the predetermined chemical reaction process, the mass spectrometer is used to continuously detect the large molecular weight product on-line, and the detection data is recorded; efficacy. Further, the continuous on-line detection of the mass spectrometer may also include the continuous on-line detection of the reaction raw materials and other reaction products. ...

Abstract

The present invention discloses a method for screening a catalyst sample, which uses a predetermined chemical reaction course of the catalyst sample to be measured. The mode of the predetermined chemical reaction course is pulse sample injection, and at the same time a continuous on-line detection is carried out for the predetermined chemical reaction course by using a velocitron. Afterwards, the catalysis efficiency of the used catalyst sample to be measured is determined according to the detection data. The mass spectrometric analysis method is comparatively simple, and quickly finishes the screening for a plurality of catalyst samples, thereby improving the exploitation efficiency of the catalyst.

Description

【Technical field】 [0001] The invention relates to a method for screening catalyst samples. 【Background technique】 [0002] With the development of modern industry, catalysts play an increasingly important role in the production of industrial products, especially in the production of chemical products. For example, in modern oil refining, chemical and environmental protection industries, more than 90% of chemical processes and more than 60% of chemical product production processes require the participation of catalysts. [0003] Furthermore, for some chemical reactions, without the participation of a catalyst, the amount of predetermined chemical reactions in the raw materials used will be very small, and the process will be extremely slow; and one or more of them will occur simultaneously in the raw materials Unintended reactions (side reactions); this situation is quite common in organic chemistry. At this time, the role of the added catalyst is not only to accelerate the...
