The direct conversion of propane and butane fraction (existing as mixtures rather than separate products) to methanol as well as the reaction mechanism under visible light source (λ=420 nm) and the catalytic action of •NO2 have been evaluated. The purpose of this work is to explore novel pathways for the production of methanol by suggesting a simplified model and result-oriented scheme to avoid the drawbacks associated with methane activation (incredibly high activation energy of about 440 kJ/mol even under mild processing conditions) in the course of its transformation to methanol which is characterized by high yield and selectivity. It is important to consider propane and butane fraction (recovered from primary crude oil distillation and by cracking of heavy molecules) as a possible feedstock for methanol production exhibiting a sufficiently high degree of conversion per pass. Thereby, a relatively simple and economical method for methanol production from refined crude oil composed of propane and butane (a one step co-processing) have been tendered.
