Abstract
The present disclosure provides for ambient temperature catalyst compositions for trace contaminant control (e.g., for environmental control assemblies for space systems) and related methods of fabrication and use. More particularly, the present disclosure provides for ambient temperature catalytic oxidation (ATCO) catalyst compositions for trace contaminant control with improvements to carbon monoxide and hydrogen capture, and related methods of fabrication and use.
Claims18
A method for fabricating an ambient temperature catalytic oxidation catalyst composition comprising:
- loading mesh granular activated carbon material into a rotating cylinder abrasimeter and subjecting the mesh granular activated carbon material to abrasion via the abrasimeter;
- screening the abraded granular activated carbon material with a 6 US mesh screen;
- washing the screened granular activated carbon material with water, and then drying the screened granular activated carbon material in a heating oven;
- further screening the dried granular activated carbon material with a 6 US mesh screen to produce a 4×6 US mesh granular activated carbon material;
- loading the 4×6 US mesh granular activated carbon material into a container, and adding a solution of chloroplatinic acid to the 4×6 US mesh granular activated carbon material;
- loading the container into a rotary evaporator, and rotating the rotary evaporator to remove water from the container;
- removing the 4×6 US mesh granular activated carbon material from the container and heating the 4×6 US mesh granular activated carbon material in an oven to produce a platinum on the 4×6 US mesh granular activated carbon material catalyst composition.
