Question
One method for the production of syngas "(mixture of CO and H2) is the catalytic conversion of CH4 with steam at high temperature and atmospheric pressure. CH 4 (g) + H 2 O (g) → CO (g) + 3H2 (g)
The only other reaction considered here is the water-gas-exchange reaction: CO (g) + H 2 O (g) → CO 2 (g) + H 2 (g)
Reagents are fed into the system at a ratio of 2.5 moles of steam: 1 mol of CH4 and heat is added to the reactor to bring the products to a temperature of 1400 K. CH4 is completely converted. It contains 10 mol% CO in the product. Assuming that the reactants are preheated to 600 K, calculate the heat requirement for the reactor.
