Non-catalytic upgrading of 4-methylanisole is investigated in DBD plasma reactor.
Electron energy, temperature and density are the key parameters.
Demethylation, transalkylation, and hydrogenolysis are the main three reactions.
The highest conversion (29.8%) achieved when pure Ar is used as a carrier gas.
4-Methylphenol, 2,4-dimethylphenol and p-xylene are the main products.
