At 500 K CH3OH, CH4, and other hydrocarbons can be formed from CO and H2. Until recently the main source of the CO mixture for the synthesis of CH3OH was methane: CH4(g)+H2O(g)=CO(g)+3H2(g). When coal is used as the source, the "synthesis gas" has a different composition: C(graphite)+H2O(g)=CO(g)+H2(g). Suppose we have a catalyst that catalyzes only the formation of CH3OH. a) What pressure is required to convert 25% of the CO to CH3OH at 500K if the synthesis gas comes from CH4? b) If the synthesis comes from coal? (Answer 10.3, 22.0 bar)

    A synthesis gas stream consisting of 65.30% H2, 34.30% CO, and 0.400% CH4 (by mole) is fed into the process described below at a rate of 100 mol/hour. The effluent stream from the reactor is fed into a separator where the methanol is completely removed, and the unconverted reactants are recycled to the reactor. To avoid the buildup of methane, a portion of the recycled stream is purged. At present operating conditions, the CO conversion over the entire process is...
