Data from: The guiding role of pre-coking on the coke deposition over ZSM-5 in methanol to propylene
Deposition of carbonaceous compounds was used to improve the propylene selectivity of ZSM-5 by deactivating some acid sites meanwhile maintaining the high activity for methanol conversion. The carbonaceous species of pre-coked samples before and after MTP reactions were investigated by elementary analysis and Thermo Gravimetric Analyzer (TGA). The results showed that pre-coke formed at low temperature (250 ℃) was unstable and easily to transform into polyaromatics species at the high reacting temperature. While combing 5% pre-coking process with 95% stream treatment at high temperature (480 ℃) was effective in inhibiting the formation of coke deposits and presented an significant improvement in the propylene selectivity.
Methanol (CH3OH), acetylene (C2H2), and propylene (C3H6) point-sources detected by the IASI infrared satellite instrument (2007-2023).
<p>This dataset includes the super-sampled IASI 0.01° × 0.01° CH3OH, C2H2, C3H6, and SO2 HRI dataset in GeoTIFF format and the catalogue of identified and categorized point-sources of CH3OH, C2H2, and C3H6 in kml format. The oversampling, wind rotation and supersampling prorcedure and codes are available in the paper of Clarisse <em>et al.</em> (2019) at <a href="https://doi.org/10.5194/amt-12-5457-2019">https://doi.org/10.5194/amt-12-5457-2019</a>.</p>
