Abstract
This invention relates to a supported catalyst for synthesizing ammonia (NH3) from nitrogen gas (N2) and hydrogen gas (H2), method of making the support, and methods of decorating the support with the catalyst.
Claims45
An ammonia catalyst comprising:
- a barium calcium aluminum oxide support material decorated with a catalytic metal;
- and
- at least one dopant of a gallium, a boron, or an indium.
A method to produce a catalyst support material, comprising:
- combining at least one barium contributor, at least one calcium contributor, and at least one aluminum contributor at a ratio of between about 1 and about 10 of the barium contributor:between about 1 and about 10 of the calcium contributor:between about 1 and about 10 of the aluminum contributor to form a first mixture;
- comminuting the first mixture to form a comminuted mixture;
- mixing the comminuted mixture with a solvent to form a slurry or a paste;
- drying the slurry or paste to form a second mixture;
- and
- annealing the second mixture to form the catalyst support material.
