Catalytic Upgrading of Biomass Pyrolysis Products Using Re-Sn/Zsm-5

The main purpose of this study was to produce valuable compounds by using biomass catalytic pyrolysis# for this purpose, beech wood was selected as a suitable biomass due to its availability and economic costs and the country's high potential for production# based on the studies, the zsm-5 catalyst was upgraded after impregnation with rhenium and tin then was used in the process# structural catalysts were also determined by sem and bet methods# in this study, three parameters of rhenium and tin’s loading percentage and biomass to catalyst ratio were changed as three influencing factors in an allowable interval# among the products synthesized by catalytic pyrolysis of the feed, heterocyclic as well as aromatic compounds were considered due to their high economic value and wide range of application, and finally the heterocyclic to aromatic ratio was selected as a target function# the maximum value of the objective function was 1#18#
