Abstract:

Solid catalyst shaping technology serves as a pivotal link between laboratory development and industrial application, directly determining the catalyst’s mechanical stability, mass transfer efficiency, and catalytic performance. Focusing on tableting technology, this study systematically analyses the synergistic regulation mechanism of catalyst powder properties (particle size, surface characteristics, flowability), forming aids (binders, lubricants, gelling agents), and tableting process parameters (pressure, holding time, die dimensions) on forming outcomes. It delves into the influence patterns of the forming process on key catalyst properties such as mechanical strength, pore structure, and catalytic activity. Furthermore, it elucidates the application of shaped catalyst design and computational fluid dynamics (CFD) simulation in optimising reactor flow field distribution and reaction efficiency. Finally, the paper outlines future development directions for tableting technology, providing theoretical underpinnings and technical references for the controlled preparation of industrial catalysts with high stability and catalytic performance.
