Abstract
Described herein are catalytic converter substrates or cores based on triply periodic minimal surfaces (TPMS) geometries, along with methods of making and using the same.
Claims10
A catalytic converter comprising:
- a casing forming an inlet and an outlet, wherein the casing forms an enclosed volume via which the inlet and the outlet are in fluid communication;
- and
- a catalytic element disposed within the enclosed volume, wherein the catalytic element comprises one or more catalyst materials and unit cells arranged in three dimensions, wherein the catalytic element has cavities that are interconnected to accommodate a flow of exhaust gas received by the inlet to pass through the cavities of the unit cells to the outlet, and wherein the casing encloses the flow of exhaust gas from the inlet to the outlet, and wherein catalytic element comprises triply periodic minimal surfaces that define a plurality of the cavities.
