Description
Technical field
The present invention relates to a kind of chemical industry apparatus, be specifically related to a kind of catalyzer and select the research experiment device.
Background technology
Catalyst Design is the most challenging task in the heterogeneous catalyst research field, although the most of catalyzer that use in the industry at present all are the products through experience and course of reaction design.But how reasonably to design catalyzer on the foundation, to guarantee catalyst quality, stable performance, be the target of research and development new catalyst.It has been generally acknowledged that the catalytic activity of catalyzer per surface area depends primarily on its chemical composition, but to identical chemical composition, its catalysis characteristics depends on Preparation of catalysts method and preparation condition to a great extent again.Different preparation and condition can change the chemical constitution (extent of reaction between combined form, compound) and the physical arrangement (grain size, crystal formation, lattice imperfection, pore structure, surface structure and shape structure etc.) of catalyzer, thereby make its catalysis characteristics significantly different.Good industrial catalyst should have high activity, and selectivity is good, and the life-span is long, and physical strength is high, regeneration easily, and cost is low, the advanced index of aspects such as raw material self-sufficiency.Reach these indexs, need careful screening of experience and the process of manufacturing experimently repeatedly.
When increasing catalyticing research worker recognizes that day by day there are many shortcomings in traditional investigative technique at the aspects such as optimization of Preparation of catalysts, screening, performance evaluation and catalytic process operating parameter,, combinatorial chemistry technique brings once huge revolution for traditional catalyticing research method so being introduced the assembly catalyze technology that the catalyticing research field forms.Research method with traditional is compared; The assembly catalyze technology not only can greatly reduce the cost of development of catalyzer, apace the evaluate catalysts system, optimize the operations factor of catalytic reaction process; And, can not bring influence to environment because the amount of employed reaction reagent and catalyzer is considerably less.But it is not to be different from tradition research fully, but has optimized the methods of traditional research, has considered numerous factors, has improved efficiency of research and development.In addition; Because the automaticity of assembly catalyze technology is high; Not only can carry out high strength ground and estimate continuously, and artificial interference factor reappearance few, experimental result is very good, can avoid fully because of different preparations and operating conditions lead to errors conclusion and result to catalyzer.Filtering out the catalyzer with best catalytic activity from containing hundreds and thousands of target compounds or having the combination catalyst storehouse of expection catalytic performance, for traditional evaluation test method, is what be difficult to accomplish.To the new catalyst system that existing catalyst system reappraises and utilize this technological development to have application prospect, be the main focus and emphasis of present assembly catalyze research.
Therefore, the exploration of conventional catalyst punishment is very long consuming time.Obviously, classic method is not enough to realize catalyst research development synthetic fast and rapid evaluation.
Summary of the invention
