Description

technical field [0001] The invention relates to a multi-tubular combined reaction device, in particular to a multi-tubular combined reaction device in the field of catalysis. Background technique [0002] In the petrochemical field, the research and development of catalysts has always been the main driving force for the rapid development of the petrochemical industry. For now, the research and development of most catalysts still mainly rely on the screening and evaluation of a large number of catalysts for exploration and research. In general, the successful development of an industrial catalyst usually requires thousands or even tens of thousands of evaluation and screening experiments. Obviously, such a huge catalyst evaluation and screening work has been one of the main bottlenecks in some catalyst development processes. On the other hand, in the development process of new catalysts, in-depth analysis of reaction mechanism, accurate descri...
