Answer 1

Answer:

Production And Applications Of Hydrogen

The most important industrial method for the production of hydrogen is the catalytic steam–hydrocarbon process, in which gaseous or vaporized hydrocarbons are treated with steam at high pressure over a nickel catalyst at 650°–950° C to produce carbon oxides and hydrogen: CnH2n+2 + nH2O → nCO + (2n + 1)H2; CnH2n+2 + 2nH2O→ nCO2 + (3n + 1)H2. The primary reaction products are processed further in various ways, depending on the desired application of the hydrogen. Another important process for hydrogen production is the noncatalytic partial oxidation of hydrocarbons under elevated pressures: CnH2n+2 + (n/2)O2→ nCO + (n + 1)H2. This process requires a feed system for delivering precise rates of fuel and oxygen, burners of special design to give rapid mixing of the reactants, a refractory-lined reactor, and a cooling system to recover heat from the effluent gases. The latter process is exothermic (heat producing), in contrast to the endothermic (heat absorbing) steam–hydrocarbon process.
