Natural gas?

Natural gas is very abundant in many middle eastern oil fields. However the costs of shipping the gas are high because it is necessary to liquefy the gas, which is mainly methane and thus has a boiling point of -164 C. One possible strategy is to oxidize the methane to methanol. CH3OH which has a boiling point of 65 C and can therefore be shipped more readily. Suppose that 10.7 x 10^9 ft3 of methane at atmospheric pressure and 25 C are oxidized to methanol.

a. what volume of methanol is formed if the density of CH3OH is 0.791 g/mL? write balanced chemical equations for the oxidation.
b. write balanced chemical equations for the oxidation of methane to methanol, the combustion of methane and the combustion of methanol
c. calculate the total energy required to convert the methane to methanol if the enthalpy produced is 125.9 KJ per mole of methane
d. calculate the total energy produced combusting the methane

Methane does not oxidize to Methanol. Methane oxidizes to CO2 and H2O. Simply balancing equations to get what you want as the end product does not work. One of the most dangerous reactions is to expose liquid oxygen to liquid methane. Methanol also oxidizes to CO2 and H2O and freezes at -94 C. “Thermatoga microorganisms are known to play a role in the anaerobic oxidation of hydrocarbons to alcohols, organic acids and carbon dioxide.” but microorganisms cannot survive at low temperatures. However, methane currently can be converted with water to Hydrogen gas and CO2 at 1100 C in the presence of a catalyst.

Power Hungry: The Myths of Green Energy and the Real Fuels of the Future $8.67 The promise of “green jobs” and a “clean energy future” has roused the masses. But as Robert Bryce makes clear in this provocative book, that vision needs a major re-vision. We cannot—and will not—quit using carbon-based fuels at any time in the near future for a simple reason: they provide the horsepower that we crave. The hard reality is that oil, coal, and natural gas ar…
