Ex situ catalytic biomass pyrolysis using mesoporous Ti-MCM-41
Biomass has attracted considerable attention as energy, economic, and environmental asset, as result of its abundance and range of properties. The use of mesoporous catalysts during fast pyrolysis has been a highly important route to improve efficiency as well adding value to biomass. The addition...

| description |
Biomass has attracted considerable attention as energy, economic, and environmental asset, as result of its abundance
and range of properties. The use of mesoporous catalysts during fast pyrolysis has been a highly important route to
improve efficiency as well adding value to biomass. The addition of titanium to molecular sieves increases the efficiency
of the pyrolysis reaction by improving production and selectivity of products of interest. This study aims at analyzing
the catalytic pyrolysis products of elephant grass using titanium catalysts prepared at different Si/Ti molar ratios, i.e., 25
and 50. The material was supported on MCM-41 for the catalytic pyrolysis of biomass. The biomass pyrolysis reactions
were performed in a micropyrolyzer coupled to a GC/MS analyzer. The Ti-MCM-41 samples were characterized by
XRD, BET-specific area, and UV-visible. The distribution of pyrolysis products depended on process parameters such as
temperature and catalyst type. The highest yield for hydrocarbon production, such as styrene, benzene, methylbenzene,
and naphthalene, was observed at 600 °C using Si/Ti equal to 50 |
