Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional single-stage reactor systems are used for catalyst testing, then the device complexity is low, but the measurement precision and manufacturing precision of catalytic process characterization are insufficient
Solution Approach 1:
The invention divides the catalytic process characterization into multiple sequential reaction stages, with each stage performed in a separate tubular reactor. This segmentation allows precise control and measurement of intermediate products at each stage, thereby improving characterization accuracy while systematically managing the overall process complexity through modular reactor design.
Solution Approach 2:
The invention transitions from conventional single-stage testing to multi-stage sequential reaction processes, adding the dimension of reaction stage progression. This enables the characterization of catalyst performance across multiple conversion levels and process conditions, significantly enhancing measurement precision by capturing intermediate reaction states that would be impossible to observe in single-stage systems.
2Adaptability or versatility
If multi-stage reaction processes with different catalyst systems are implemented, then the adaptability of the testing system improves, but the device complexity and operational complexity increase
Solution Approach 1:
Each reaction stage is implemented in a separate tubular reactor, allowing independent selection and optimization of catalyst systems for each stage. This segmentation provides high adaptability for testing different catalyst combinations while managing complexity through standardized reactor modules that can be configured in sequence.
Solution Approach 2:
The invention employs universal tubular reactor modules that can accommodate different catalyst systems and reaction conditions. Each reactor is designed with standardized features (heating zones, catalyst loading, product sampling) that enable the same reactor type to perform multiple function across different reaction stages, thereby improving versatility without proportionally increasing device complexity.
3Measurement precision
If intermediate sampling is performed frequently to monitor reaction progress, then the measurement precision improves, but the loss of time and productivity decrease due to disruptions
Solution Approach 1:
By segmenting the reaction process into discrete stages with separate reactors, the system captures intermediate products at defined conversion points without requiring frequent sampling during continuous operation. Each reactor stage acts as a natural sampling point, providing precise measurement of reaction progress while maintaining continuous flow and minimizing disruptions to productivity.
Solution Approach 2:
The reaction conditions and stage durations are pre-optimized to achieve target conversion levels in each reactor stage before product removal. This preliminary action approach allows the system to reach predetermined reaction states without intermediate sampling interruptions, thereby maintaining both measurement precision and continuous operation for high productivity.
4Productivity
If parallel reaction trains with different numbers of tubular reactors are used, then the productivity and data generation rate improve, but the device complexity and ease of operation worsen
Solution Approach 1:
The parallel reaction trains are segmented into standardized modules with identical reactor configurations. Each train processes different catalyst formulations or conditions using the same multi-stage reactor design, enabling high productivity through parallel data generation while simplifying operation through modular, repeatable units that follow consistent procedures.
Solution Approach 2:
The invention maintains operational simplicity by changing parameters (catalyst type, reaction conditions, train configuration) rather than changing the fundamental reactor structure or operation procedure. Each parallel train uses the same standardized operating protocol, allowing high productivity through parameter variation while keeping ease of operation intact through procedural consistency.

AI summary
The present invention relates to a method for characterizing catalytic processes, which comprises a reaction system having two or more reaction lines arranged in parallel, wherein one single reaction line comprises a plurality of reaction chambers connected in series or one individual reaction chamber. In the method, which is also referred to as a CKP method, a reactant flow is supplied to every reaction line. The reactant flows supplied to the reaction lines are subjected to different numbers of process steps in the different reaction lines. The product flows withdrawn from the reaction lines are subjected to an analytical characterization, wherein the data acquired during the characterization are correlated, wherein a difference calculation is preferably included here. The CKP method is very versatile in use and is characterized by a very high degree of accuracy. The mass balancing achieves a standard deviation of +/- 10 wt.% or below. Furthermore, the invention relates to a device for carrying out the CKP method or to a device for simultaneously carrying out a plurality of CKP methods. The invention thus also relates to the field of high throughput research.
