Catalytic oxidation of methane to formaldehyde. Computer modeling for chemical engineering evaluation

摘要

Evaluation of process variables of catalytic oxidation of methane into formaldehyde obtained in continuous flwo, continuous flow reccyle and flow recycle batch laboratory reactors based on theoretical and mathematical statistical considerations is carried out. A set of two linearly independent reactions is defined and introduced as multistep overall reaction mechanism in the conseration equations. Arrhenius parameters are evaluated by statistical methods. Conversion of methane, selectivity, yield and sapce-time yield are computed in function of catalyst concentration, reaction temperature and residence time. Based on their analysis viable process parameters and the type of continuous flow recycle reactor are suggested for chemical engineering purposes.
