4.75. A catalytic reactor is used to produce formaldehyde from methanol in the reaction HCHO+ H2 CH-OН A single-pass conversion of 60.0% is achieved in the reactor. The methanol in the reactor product is separated from the formaldehyde and hydrogen in a multiple-unit process. The production rate of formaldehyde is 900.0 kg/h. (a) Calculate the required feed rate of methanol to the process (kmol/h) if there is no recycle. (b) Suppose the unreacted methanol is recovered and recycled to the...

Formaldehyde is manufactured by the catalytic oxidation of methanol, using excess air: CH_3OH + 1/2 O_2 rightarrow HCHO + H_2O If the reactor conditions are not properly controlled, a secondary oxidation occurs: HCHO + 1/2 O_2 rightarrow HCOOH The measured product gas composition from a test run is given in table Q_2. Determine the percentage conversion of methanol to formaldehyde (methanal). Find the percentage conversion of methanol to formic acid (methanoic acid). Calculate the molar ratio of air to methanol...

A simplified version of the process for the manufacture of formaldehyde (HCHO) is shown in the Figure below. Methanol (CH3OH) is oxidized to formaldehyde using air as the source of oxygen as per the following reaction: CH2OH + 2202 HCHO + H2O The reactor is a fixed bed containing an iron-molybdenum oxide catalyst. The reactor feed, stream 4, contains 8 mol% methanol and 10 mol% oxygen. The methanol is completely converted in the reactor. A purge stream (primarily for nitrogen)...
