Abstract
Methods for bi-reforming with a red mud catalyst support composition, one method including providing a methane feed in the presence of carbon dioxide and steam to react over the red mud catalyst support 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.
Claims15
A method for bi-reforming with a red mud catalyst support composition, the method comprising the steps of:
- providing a methane feed in the presence of carbon dioxide and steam to react in a bi-reforming reaction over the red mud catalyst support composition at a temperature between about 500° C. to about 1000° C. and a pressure between about 5 bar and about 20 bar to produce synthesis gas comprising H2 and CO, the red mud catalyst support composition comprising:
- red mud waste material produced from an alumina extraction process from bauxite ore with a weight ratio of aluminum oxide to iron oxide of about 1:0.74 and a weight ratio of aluminum oxide to titanium oxide of about 1:0.27, where produced H2 is at least about 1 mol. % of produced products from the bi-reforming reaction for at least about 5 hours.
