| Abstract: | Based on the reaction process mechanism and plant experiments the mathematical models for formaldehyde process are developed. It is shown through simulation study that at a given reaction temperature, the methanol conversion increases, while the selectivity to formaldehyde decrease with the increasing of the oxygen to methanol ratio. With yield as the objective function, subject to quality and reaction rate of production, optimum condition is obtained.It is shown that by means of off-line computer control to keep the plant is this operating condition the higher quality of product can be guaranteed, raw meferiul comsuption reduced and the life of catalysts prolonged. |
