Methane and oxygen react in the presence of a catalyst to form formaldehyde. In a parallel reaction, methane is oxidized to carbon dioxide and water. CH4 + O2 HCHO + H20 CH4 + 202 CO2 + 2H20 The feed to the reactor contains equimolar amounts of methane and oxygen. Assume a basis of 100.0 mol feed/s. a. How many degrees of freedom remain for the overall process? i b. The fractional conversion of methane is 0.890 and the fractional yield of formaldehyde is 0.870 mol HCHO/mol CH4 fed. What is the composition of the output stream? mol% O2 b. The fractional conversion of methane is 0.890 and the fractional yield of formaldehyde is 0.870 mol HCHO/mol CH4 fed. What is the composition of the output stream? mol% O2 mol% HCHO mol% H2O mol% CO2 mol% CH4 c. What is the selectivity (mol HCHO/mol CO2) of the process? mol HCHO/mol CO2 e Textbook and Media
