Abstract
A porous catalyst useful in the conversion of carbon dioxide to one or more hydrocarbons, the porous catalyst containing: (i) a bimetallic oxide portion containing at least one of iron oxide and nickel oxide or carbide in combination with at least one oxide, hydroxide, and/or carbide of at least one of manganese, cobalt, copper, yttrium, zirconium, niobium, hafnium, zinc, and lanthanides; and (ii) an alkali metal oxide, hydroxide, or carbonate portion in contact with the bimetallic oxide portion; wherein the porous catalyst contains pores in the bimetallic oxide portion. A method of using the porous catalyst to convert carbon dioxide to hydrocarbons, particularly olefins, containing at least four carbon atoms, is also described.
Claims20
A porous catalyst useful in the conversion of carbon dioxide to one or more hydrocarbons, the porous catalyst comprising:
- (i) a bimetallic oxide portion comprising at least one of iron oxide and nickel oxide in combination with at least one oxide, hydroxide, and/or carbide of at least one of manganese, cobalt, copper, yttrium, zirconium, niobium, hafnium, zinc, and lanthanides;
- and
- (ii) an alkali metal oxide, hydroxide, or carbonate portion in contact with the bimetallic oxide portion;
- wherein the porous catalyst contains pores in the bimetallic oxide portion.
A method of converting carbon dioxide to one or more hydrocarbons at least a portion of which contain four carbon atoms, the method comprising contacting carbon dioxide (CO2) and hydrogen (H2) gases with a porous catalyst at a temperature of 100-800° C. at a pressure of 1-20 atm to result in conversion of the carbon dioxide to said one or more hydrocarbons, wherein the porous catalyst comprises:
- (i) a bimetallic oxide portion comprising at least one of iron oxide and nickel oxide in combination with at least one oxide, hydroxide, and/or carbide of at least one of manganese, cobalt, copper, yttrium, zirconium, niobium, hafnium, zinc, and lanthanides;
- and
- (ii) an alkali metal oxide, hydroxide, or carbonate portion in contact with the bimetallic oxide portion;
- wherein the porous catalyst contains pores in the bimetallic oxide portion.
