Claims21
A method of producing at least one product comprising a hydrocarbon having a formula CnHz where n is a positive integer equal to or greater than 1, where n is equal to 1 only where the carbon source is carbon dioxide, and z is an integer between 2n+2 and 2n, and hydrogen gas comprising the steps of:
- forming a reaction mixture of a gaseous carbon source represented by the letter W, selected from the group consisting of CH4 and CO2, and H2O in a reaction vessel having a catalyst and at least one microwave energy source, said reaction mixture in the presence of said catalyst and thermal energy undergoing at least one reaction comprising:
- W+nH2O→CnHz+nH2O+yH2;
- wherein W comprises at least n carbon molecules and n is a positive integer equal to or greater than 1, where n is equal to 1 only where the carbon source is carbon dioxide, and z is an integer between 2n+2 and 2n, the carbon source comprises at least some CH4, and Y is zero or a positive integer to balance the hydrogen;
- said catalyst is selected from the group of iron-, cobalt-, copper- and nickel-containing compounds where at least one selected catalyst upon microwave radiation increases in temperature to produce thermal energy;
- placing thermal energy to the catalyst by said microwave energy source and to said reaction mixture to produce at least one product selected from the group consisting of a hydrocarbon composition having a formula CmHz and hydrogen gas.
An apparatus for producing a product comprising at least one of the group comprising a hydrocarbon having a formula CnHz where n is a positive integer equal to or greater than 1, where n is equal to 1 only where the carbon source is carbon dioxide, and z is an integer between 2n+2 and 2n, and hydrogen gas, comprising:
- a reaction vessel for containing a reaction mixture of a gaseous carbon source represented by the letter W, selected from the group consisting of CH4 and CO2, and H2O, and having a catalyst and at least one microwave energy source, said reaction mixture in the presence of said catalyst and thermal energy undergoing at least one reaction comprising:
- W+nH2O→CnHz+nH2O+yH2;
- wherein W comprises at least n carbon molecules and n is a positive integer equal to or greater than 1, where n is equal to 1 only where the carbon source is carbon dioxide, and z is an integer between 2n+2 and 2n, the carbon source comprises at least some CH4, and Y is zero or a positive integer to balance the hydrogen;
- said catalyst is selected from the group of iron-, cobalt-, copper- and nickel-containing compounds where at least one selected catalyst upon microwave radiation increases in temperature to produce thermal energy;
- said microwave energy source for placing thermal energy to the catalyst and to said reaction mixture to produce at least one hydrocarbon composition having a formula CmHz and hydrogen gas.
