Multiple adiabatic bed PCR
MAB PCR - a novel combination of proven technologies
In the multiple adiabatic bed PCR (MAB PCR)* we have extended our proven Printed Circuit Heat Exchanger (PCHE) technology to include heterogeneous catalysis. MAB PCR effectively separates the functions of heat transfer and chemical reaction, allowing each to be optimised independently. * Patents pending
Why compromise on conflicting chemical reaction and heat transfer requirements?
MAB PCR offers improved selectivity or productivity through:
Close temperature control, through
- Multiple, smaller reaction steps
- Multiple inter-stage heat exchange
Optional reactant addition at each step Optimised catalyst bed aspect ratio Smaller catalyst particles - higher catalyst effectiveness Reduced adiabatic residence time
MAB PCR combines two established technologies - alternating adiabatic catalytic reactor beds and heat exchangers - and is suitable for applications ranging from fuel processing to the production of fine and bulk chemicals
The PCHE cores used for heat exchange are constructed from flat metal plates into which fluid flow channels are chemically etched. These etched plates are then stacked and diffusion bonded, converting the plates into a solid metal block containing precisely engineered fluid flow passages.
Staged reactant addition and mixing of reactants can be achieved by etching a network of fluid distributor channels into the plates. These perform passage-by-passage mixing of process fluids and uniformly distribute process streams into catalyst beds.
The MAB PCR design and manufacturing technique offers:
Highly compact heat exchangers, with high thermal effectiveness Close temperature control, enabling
-
- Increased reaction temperature
- Optimised reaction temperature profile
- Elimination of hot spots
Addition and mixing of reactant (or removal of product) at each stage Elimination of interconnecting piping (and resulting stagnant areas), and the need to redistribute reactants Catalyst beds with a large flow area and short flow path, permitting the use of smaller, high effectiveness catalyst particles Decoupling of heat transfer and catalyst volumes, so that neither determines the sizing of the other
MAB PCR is suitable for:
Industrial bulk chemical production Compact plant, for distributed manufacture Micro-reactors
