Question
Two reactions take place in a continuous reactor operating at steady state,
C2H6 → C2H4 + H2
C2H6 + H2 – 2CH4
The feed stream contains 85.0 mole % ethane (C2H6) and 15 mole % inert (i.e. unreactive)
components. The fractional conversion of ethane is 0.501, and the fractional yield of ethylene
(C2H4) is 0.471.
a. What is the molar composition of the product gas?
b. What is the selectivity of ethylene to methane (CH4) production?
