Question $2)(24$ p$.)$

$C{H}_{2}O+\frac{1}{2}{O}_{2}H\frac{C}{O}OH($side reaction$)$

reactions:

$C{H}_{3}OH+\frac{1}{2}{O}_{2}C{H}_{2}O+H_{2}O($main reaction$)$ and $C{H}_{3}OH$ and some air, and the output stream contaitery.

The input stream to the reactor contains $80mo\frac{l}{s}C{H}_{2}O,$ some $C{H}_{3}OH,$ and some $O_2.$

$mo\frac{l}{s}{N}_2,26mo\frac{l}{s}{H}_{2}O,8mo\frac{l}{s}$HCO in the reactor.

a$)$ Find the $O_2$ amount used in the reactor.

b$)$ Find the yield of formaldehyde.

c$)$ Find percentage conversion of methanol.

d$)$ Find selectivity of $C{H}_{2}O$ over $H\frac{C}{O}OH.$

Answers:

$O_2$ used $=$

$mo\frac{l}{s}$

$C{H}_{2}O$ Yield $=$

$C{H}_{3}OH$ conversion $=$

$.\%$

$(C{H}_2\frac{O}{H}\frac{C}{O}OH)$ selectivity $=.$
