Abstract

Embodiments of the present disclosure describe pre-catalysts comprising including one or more of indium oxide, indium hydroxide, indium oxyhydroxide, an active oxide, and a refractory oxide. Embodiments of the present disclosure also describe method of making pre-catalysts based on one or more of impregnation, precipitation or co-precipitation, ball milling, and metal-organic framework (MOF)-mediated synthesis. Embodiments of the present disclosure further describe methods of activating pre-catalysts and synthesizing one or more of methanol and olefins using catalysts obtained from the pre-catalysts.

First claim

What is claimed is:

1. A pre-catalyst, comprising:
both of indium hydroxide and indium oxyhydroxide mixed with an active oxide and carbon source;

wherein the active oxide includes a mixed valence metal oxide.

2. The pre-catalyst of claim 1 , wherein the active oxide is a reducible oxide.

3. The pre-catalyst of claim 1 , wherein the active oxide includes one or more of cobalt, nickel, copper, manganese, iron, and vanadium.

4. The pre-catalyst of claim 1 , further comprising a refractory oxide.

5. The pre-catalyst of claim 4 , wherein the refractory oxide includes one or more of zirconium dioxide (ZrO 2 ), silica (SiO 2 ), alumina (Al 2 O 3 ), gallium oxide (Ga 2 O 3 ), cerium oxide (CeO 2 ), vanadium oxide (V 2 O 5 ), chromium oxide (Cr 2 O 3 ), titanium dioxide (TiO 2 ), magnesium oxide (MgO), zinc oxide (ZnO), tin oxide (SnO 2 ), and carbon black (C).

6. The pre-catalyst of claim 1 , wherein a form of the catalyst is one or more of extrudates, granules, spheres, monoliths, particles, and pellets.

7. The catalyst of claim 1 , wherein the catalyst further comprises one or more of lubricants, peptizers, plasticizers, porogens, binders, and fillers.

8. The pre-catalyst of claim 1 , wherein the pre-catalyst includes the carbon source and wherein the carbon source is a carbonate.

9. The pre-catalyst of claim 1 , wherein the pre-catalyst includes the active oxide and wherein the active oxide includes nanoparticles.

10. The pre-catalyst of claim 1 , wherein the pre-catalyst includes indium hydroxide and the active oxide, and wherein the active oxide is Co 3 O 4 , and wherein the indium hydroxide is supported on the active oxide.
