Abstract
The present disclosure provides a composition. In an embodiment, a catalyst composition is provided and includes from 85 mol % to 95 mol % iron metal, and from 15 mol % to 5 mol % indium metal, wherein mol % is based on total moles of iron metal and indium metal. Also provided is a process of contacting, under reaction conditions, a gaseous mixture of carbon monoxide, hydrogen and optionally water with the catalyst composition. The process includes forming a reaction product composed of light olefins.
Claims16
A catalyst comprising:
- a metallic catalytic composition consisting of:
- from 85 mol % to 95 mol % iron metal;
- from 15 mol % to 5 mol % indium metal, and
- a support impregnated with the metallic catalytic composition in a nanoparticle form, wherein the nanoparticle form of the metallic catalytic composition is defined by at least one iron salt and at least one indium salt having been introduced to the support then exposed to a reduction agent to reduce the iron salt and indium salt into the iron metal and the indium metal to form the catalytic composition on the support;
- wherein mol % is based on total moles of iron metal and indium metal.
A metallic catalytic composition consisting of:
- from 85 mol % to 95 mol % iron metal;
- from 15 mol % to 5 mol % indium metal,
- wherein mol % is based on total moles of iron metal and indium metal.
A catalyst consisting of:
- a metallic catalytic composition consisting of:
- from 85 mol % to 95 mol % iron metal;
- from 15 mol % to 5 mol % indium metal, and
- having a support impregnated with at least one iron salt and at least one indium salt and exposed to a mixture of H2/N2 gas to provide the iron metal and the indium metal on the support;
- wherein mol % is based on total moles of iron metal and indium metal.
A catalyst consisting essentially of:
