(a) GC-MS chromatograms of the continuous-flow methanol conversion over HZSM-5 in a fix-bed reactor under the linear temperature increase from 373 to 573 K and (b) real-time tracking of the effluents by Online Mass Spectroscopy (methanol weight hourly space velocity (WHSV): 2.0 h–1, temperature ramping rate: 2 K/min). (c) In situ13C MAS NMR spectra during the 13C methanol continuous-flow conversion over HZSM-5 in an NMR rotor reactor under the condition of the linear temperature increase from 373 to 573 K (WHSV = 1 h–1, temperature ramping rate = 10 K/min, 13C MAS NMR spectra were recorded using one pulse sequence with a spinning rate of 3 kHz). (d) The apparent reaction rate of C1 reactants and the chemical shift value of DME as the function of the reaction temperature from 423 to 573 K.
