Abstract
Modified red mud catalyst compositions, methods for production, and methods for use, a composition including red mud material produced from an alumina extraction process from bauxite ore; nickel oxide, the nickel oxide present at between about 5 wt. % to about 40 wt. % of the modified red mud catalyst composition; and a Periodic Table Group VIB metal oxide, the Group VIB metal oxide present at between about 1 wt. % and about 30 wt. % of the modified red mud catalyst composition.

A modified red mud catalyst composition, the composition comprising:
- red mud material produced from an alumina extraction process from bauxite ore;
- nickel oxide, the nickel oxide present at between about 5 wt. % to about 40 wt. % of the modified red mud catalyst composition;
- and
- a Periodic Table Group VIB metal oxide, the Group VIB metal oxide present at between about 1 wt. % and about 30 wt. % of the modified red mud catalyst composition.
A method for dry reforming over a modified red mud catalyst composition, the method comprising the steps of:
- providing a methane feed and carbon dioxide feed to react over the modified red mud catalyst composition at increased temperature and increased pressure to produce synthesis gas comprising H2 and CO, the composition comprising:
- red mud material produced from an alumina extraction process from bauxite ore;
- nickel oxide, the nickel oxide present at between about 5 wt. % to about 40 wt. % of the modified red mud catalyst composition;
- and
- a Periodic Table Group VIB metal oxide, the Group VIB metal oxide present at between about 1 wt. % and about 30 wt. % of the modified red mud catalyst composition.
