Abstract
Disclosed are bulk metal oxide catalysts, and methods for their use, that include at 5 least two or more metals or two or more compounds thereof (M1, M2) and having an olivine crystal phase or a spinel crystal phase, or both phases, wherein the bulk metal oxide catalyst is capable of producing the H2 and CO from the CH4 and the CO2 under substantially dry conditions.
Claims17
A bulk metal oxide catalyst capable of producing hydrogen (H2) and carbon monoxide (CO) from methane (CH4) and carbon dioxide (CO2), wherein the bulk metal oxide catalyst consists of an olivine crystal structure that has discrete SiO44− anions and two metals (M1, M2) in the crystal lattice, a discrete spinel structure, or is a mixture thereof,
- wherein M1 and M2 are different;
- wherein the O− anions of the silicate are coordinated with the metals in the crystal lattice, and
- wherein the bulk metal oxide catalyst does not include a carrier or a support.
A catalyst comprising:
- a support comprising an olivine mineral having an olivine crystal phase, wherein the olivine mineral is selected from the group consisting of monticelite, calcio-olivine, lienbergite, glaucochroite, and any combination thereof;
- and
- two or more additional metals (M1, M2) or two or more compounds thereof.
