چکیده
|
The effect catalyst deactivation on product distribution in methanol to olefins reaction (mto) over hzsm-5 catalyst was studied# the hzsm-5 and boron-modified hzsm-5 catalysts were prepared by hydrothermal method# reaction tests were performed in a fixed-bed reactor until the end of catalyst lifetime# the anderson-schulz-flory (asf) distribution was used for the analysis of selectivity data# while the selectivity of lower olefins decreased with time-on-stream and that of c5+ hydrocarbon increased with time-on-stream, the asf distribution was retained with a slight increase in chain probability growth# the c6+ product progressively became more olefinic as a result of reduced hydrogen transfer due to catalyst deactivtion#
