Abstract

Direct conversion of methane to METHANOL is a newly developed technique by which the intermediate and expensive process of formation of synthesis gas is eliminated.The main aim of the present study is to develop a generally applicable mathematical model to predict the behavior of the direct oxidation of methane to METHANOL. The interesting point concerning this work may be the task of simultaneous solution of the reacting species mass balances equations both inside the catalysts pores (microscopic relations) and within the bulk of fluid (macroscopic relations).A large number of the studies performed in this area are solely experimental investigations without pertinent interpretation of the results. While, those considered the theoretical aspects of such a process have not gone into details of the reactions inside the catalysts pores. , In the present investigation, a DYNAMIC MODEL for the PARTIAL OXIDATION OF METHANE to METHANOL, utilizing oxygen in a fixed, bed reactor packed with V2O5 /SiO2 particles as the reaction catalyst has been developed.Considering an appropriate rate equation, the kinetic scheme of the process and the catalysts effectiveness factor have been deter mea. It has been observed that an increase m methane conversion improves the selectivity's of both CO and formaldehyde, while those of CO2; and METHANOL are decreased. In addition; the effects of temperature, pressure, oxygen concentration in feed and gas hourly space velocity (GHSV) on the conversion of methane and selectivity of the products have been investigated. The results obtained applying this model, were adequately correlated with the experimental data available in the literature.
