Catalytic pyrolysis of woody biomass

Isomerization of β-pinene oxide over Sn-modified zeolites

“…The reason for enhanced Brønsted acidity may be attributed the formation of new types of Brønsted acid sites, size of metal particles, metal-support interaction and type of structure of zeolite. Analogous phenomenon has been observed earlier in [32][33][34][35].…”

Biomass catalytic pyrolysis to produce olefins and aromatics with a physically mixed catalyst

“…(Lu et al, 2010;Wang et al, 2010). The comparison of catalytic characteristics between these catalysts has been well reviewed by some researchers (Aho et al, 2010;Lappas et al, 2012;Park et al, 2011;Stöcker, 2008). ZSM-5 has a 3-dimensional pore structure with pore size of 5.5-5.6 Å which is suitable for aromatics and olefins formation .…”

Catalytic Pyrolysis of Pine Biomass Over H-Beta Zeolite in a Dual-Fluidized Bed Reactor: Effect of Space Velocity on the Yield and Composition of Pyrolysis Products

“…The most used zeolite structure in the catalytic upgrading has so far been the ZSM-5 [7,13,14,[16][17][18][19][21][22][23][24][25][26][27][28][29], some studies have been made with the Y-zeolite [13,16,17,25,27], and some with the beta zeolite [15,16,25,29]. The different structures have different pore size and shape.…”

“…Methods used in the upgrading are: direct catalytic pyrolysis of biomass in fluidized bed reactors where the zeolites have acted as a catalytic bed material [7,[13][14][15][16], catalytic conversion of bio-oil [17][18][19][20] and bio-oil model compounds [21][22][23][24][25] and catalytic upgrading of the pyrolysis vapors without any condensation in between by Williams and Horne [26][27][28], and by Aho et al [29,30].…”
