Question

Powdered coal ( essentially pure C ) is reacted with excess water to make a mixture of CO,CO2 and H2 The reaction is desired reaction ,CO2 is an undesired waste product. This gas mixture from the reactions of coal with water is further reacted over a catalyst to make methanol (CH3OH)

The Coal is fed with 200% excess water ( excess is calculated with respect to CO formation) 100% of coal is consumed. the selectivity to CO (with respect to CO2) is 1:1 the functional conversion of the CO is 50% what is the final gas composition ? ( all final species are in the gas phase

C+H2O = CO +H2

C+2H2O = CO2 +2H2

CO+2H2O=CH3OH+1/2 O2


please explain how you get the answer........ Thanksssssssssssssss

Explanation / Answer

if 100 moles of coal is fed initially from 100 C we get 50 CO, 50 CO2, 150H2 water consumed = 150 water initially available = 200 water left aftee1st 2 reaction =50 25 CH3OH, 12.5 O2 finally = 25 CO, 50 CO2, 150 H2, 25 CH3OH, 12.5 O2 and no H2O
