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

Evaluation of process variables of catalytic oxidation of methane into form aldehyde obtained in continuous flow, continuous flow recycle and flow recy cle batch laboratory reactors based on theoretical and mathematical statist ical considerations is carried out. A set of two linearly independent react ions is defined and introduced as multistep overall reaction mechanism in t he conservation equations. Arrhenius parameters are evaluated by statistica l methods. Conversion of methane, selectivity, yield and space-time yield a re 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 engineer ing purposes.
