Requirements for RD Catalytic Packing
Before we started our work on catalyst development, we examined the requirements for catalytic packing in RD columns. From the standpoint of chemical synthesis, high activity per volume is favorable, activity and selectivity of the catalyst should be high, good accessibility of the active sites is required, and stability with regard to chemical aspects and mechanical strength is necessary. For good distillation performance the catalyst needs to have a large geometrical surface area for enhanced mass transfer, low pressure drop, good separation properties, good wetability, and good mechanical strength, to mention the most important proper ties. A cost-effective and easy production process is required by both. The integration of chemical synthesis in a distillation column will always be a compromise between the requirements of the two unit operations.
