Method for the production of light hydrocarbons from gas with high methane content, a solid oxide fuel cell used for the production of light hydrocarbons from gas with high methane content, and a catalyst for the production of light hydrocarbons from gas with high methane content

摘要

The present invention refers to the conversion of gaseous or gasifiable fuels with high methane content, such as natural gas, biogas, synthesis gas or gas originated from various industrial process rejects, with or without prior desulfurization and elimination of other contaminants, in a solid oxide fuel cell (SOFC), with special anodes, based on mixed oxides or metal oxides with a perovskite type structure, either or not nano structured, into light hydrocarbons, primarily ethylene and ethane.

主权项

1. A solid oxide fuel cell containing a cathode, an anode and an electrolyte comprising:
a nanostructured or non-nanostructured anode with a chemical composition based on lanthanum aluminate (LaAl1-xMxO3), wherein M corresponds to a chemical element from among transition elements selected from the group consisting of Mn, Cr, Ti, V, Co, Cu and x represents approximately a content in the range of 35 to 50% in mol.
