Time- and space-resolved high energy operando X-ray diffraction for monitoring the methanol to hydrocarbons reaction over H-ZSM-22 zeolite catalyst in different conditions

摘要

The conversion of methanol to hydrocarbons (MTH) over H-ZSM-22 was studied by operando time- and space-resolved X-ray diffraction (XRD) at 370-385 degrees C and WHSV = 2 g/g hat the Swiss-Norwegian Beamline at ESRF. The performance of a commercial H-ZSM-22 sample was compared before and after acid-base treatment, and with and without propanol co-feed, respectively.
