MTO Process Under Steady-State Conditions

Investigation of the MTO Process Under Steady-State Conditions 

Various mechanisms have been proposed for the conversion of MTHC on acidic zeolites under steady-state conditions 210. Recent investigations 49,113,261,289-300 have shown that the conversion of the equilibrium mixture of methanol and DME by a

In an attempt to identify the catalytic role of the hydrocarbon pool, the MTO process was further studied by CF MAS NMR spectroscopy with an alternating flow of CHsOH and CHsOH. After the conversion of CHsOH under steady-state conditions, the reactant flow was switched to CHsOH without a change the reaction parameters. If the alkyl groups of the hydrocarbon pool were involved in the conversion of methanol, for example, by adding reactant molecules and splitting off product molecules, the C-isotope abundance of these groups would be expected to decrease strongly after the switch from CHsOH to CHsOH.
