United States Patent: 7022888

 

Since we have many times documented the 1912 Nobel-winning Sabatier process, now being further refined by NASA, wherein Carbon Dioxide can be transformed into Methane; and, since we are, today, via separate dispatch, sending along report of: United States Patent: 4476249 - for a "Low Cost Method for Producing Methanol", wherein is disclosed another way, in addition to others we've reported, to produce "low cost methanol" from Coal, we wanted to again confirm that both the CO2-derived Methane and the Coal-derived Methanol can be further converted into Gasoline.

Moreover: The synthesis of Gasoline can be effected by combining such CO2-based Methane with such Coal-based Methanol.

As seen in our excerpts from the initial link in this dispatch to:

 

"United States Patent 7,022,888 - Conversion of Methane and Organic Oxygenate to Hydrocarbons

 

Date: April, 2006

 

Inventor: Vasant Choudhary, et. al., India

 

Assignee: Council of Industrial and Scientific Research, New Delhi

 

Abstract: A process for the non-oxidative conversion of methane simultaneously with the conversion of an organic oxygenate ... to gasoline range hydrocarbons ... wherein the organic oxygenate is selected from methanol and ethanol.

A number of U.S. Pat. Nos. 3,928,483 (1975), 3,931,349 (1976), and 4,05,576 (1977), 4,046,825 (1977), and 4,138,440(1979), assigned to Mobil oil corporation disclosed process for the production of gasoline from methanol, other alcohol and ether, using shape selective ZSM-5 zeolite catalyst. A commercial plant based on Mobil's methanol-to-gasoline (MTG) process, involving production of methanol from methane via syngas route: methane steam reforming to syngas and syngas conversion to methanol, was also successfully operated in New Zealand in 1985.

U.S. Pat. No. 4,814,533 (1989) discloses a continuous catalytic process for the production of higher molecular weight hydrocarbons ... from ... methane.

Summary: The process of the present invention has been developed on the basis of our findings that in the presence of a bifunctional zeolite catalyst having dehydrogenation and acidic properties and in the presence of an aliphatic alcohol ... the conversion of methane into higher hydrocarbons takes place at a temperature below 700C, overcoming the thermodynamic barrier."

We have already reported one or two of the above-referenced patents for you, and plan, in the near future, to send along expositions of the others.

However, it should be apparent from the foregoing that:

Once we have Methanol, which the Navy, as noted, knows how to make, in a "low cost" way, from Coal; and, the Methane, which, as we've earlier reported, and as now recorded by the West Virginia Coal Association, we can make, as NASA intends to do on the planet Mars, from Carbon Dioxide; we can, as herein, combine Methanol and Methane in a process that converts them both, as above, "to gasoline range hydrocarbons".
