Catalytic processes are typically carried out in a packed-bed reactors because this reactor configuration is easy to model, scale, design, construct, and operate. While this configuration offers numerous advantages, heat and mass transfer limitations are commonly encountered because relatively large particles must be used to minimize pressure drop. While these limitations can be partially addressed through appropriate reactor-tube size, operating conditions, and catalyst design, optimal catalyst performance cannot be achieved unless the catalyst is operating according to intrinsic kinetics. Regardless of the catalyst particle size employed, packed bed reactors are difficult to control during exothermic and endothermic processes because poor heat transfer induces large temperature gradients across the catalyst bed. Complicated reactor designs, including fluidized-bed and slurry-phase reactors, are commonly employed to overcome these limitations can; however, they are more complicated to design, scale, construct, and operate. IntraMicron's microfibrous entrapment technology offers a solution to minimize the heat and mass transfer limitations allowing catalytic processes to operate with enhanced efficiency. This innovation results in improved activity and selectivity as well as reduced reactor weight and volume in a simple scalable packed bed configuration.
