Answer 2

hi

here is your answer

H2 production relies on a process called steam reforming.

This involves heating steam to 800 degrees C and combining with methane (CH4) over a catalytic material. The reactions release the Hydrogen from the methane and water molecules. The freed-up Oxygen and Carbon atoms combine to form CO2. Here’s what the reaction formula looks like:

CH4 + 2H20 + heat → CO2 + 4H2

As one might guess, this produces a lot of CO2. The molecular weight of CO2 is 44, while that of the four H2 molecules is only 8. So, not counting the source of energy to heat the steam, this means that the mass ratio of CO2 is 5.5 times greater that of the H2. If we consider the energy required to heat the steam also comes from combustion of hydrocarbons, the ratio ends up somewhere in the range of about 12:1.

One of the primary uses of hydrogen is the production of ammonia, which is used for fertilizer of most of the food that humans consume. There is, (forgive the pun), much to think about when food crops such as corn are grown to produce ethanol fuel, because the total carbon footprint also must consider the fertilizer and how it was made.

hope it helps
