“…(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 .…”

“…Hydrodeoxygenation and catalytic cracking are considered two main ways to convert oxygenated bio-oil into pure hydrocarbon fuels (Czernik and Bridgwater 2004;Mortensen et al 2011). Compared with hydrodeoxygenation, zeolite catalytic cracking converts oxygenated bio-oil into pure hydrocarbon fuels without hydrogen consumption, which makes it more economical (Park et al 2011).…”

Most research on the upgrading of bio-oil by cracking has been done under atmospheric pressure, which results in a catalyst coke yield as high as 20 wt%. In this paper, pressurized cracking, as well as cocracking with methanol proved to be an effective solution for relieving catalyst deactivation. HZSM-5 catalyst was found to deactivate rapidly in the cracking process of pure ketones. However, when methanol was used as the co-cracking substance for ketones under 2 MPa, ketones reached a full conversion of 100 % without obvious catalyst deactivation. The highest selectivity of bio-gasoline phase from co-cracking of ketones and methanol reached a value of 31.6%, in which liquid hydrocarbons had a relative content of 97.2%. The co-cracking of hydroxypropanone and methanol had lower bio-gasoline phase selectivity but better oil phase quality (liquid hydrocarbons selectivity up to 99%) than those of cyclopentanone and methanol. Based on the experimental results, the promotion mechanism of methanol on cracking of ketones in bio-oil was illustrated by a co-cracking mechanism model.

“…Catalytic upgrading is frequently used to improve the fuel quality and increase the value-added of the pyrolysis product oil. 4,15 Acid catalysts, such as microporous zeolite materials (HZSM-5, HY, Hβ, etc) and mesoporous materials (MCM-41, SBA-15, MCM-48, etc), have normally been used for the upgrading of bio-oil. The atmospheric reforming of bio-oil over acid catalysts is an economical process because it does not need the supply of hydrogen gas.…”

The catalytic pyrolysis of cellulose was carried out over SAPO-11 for the first time. Pyrolyzer-gas chromatography/mass spectroscopy was used for the in-situ analysis of the pyrolysis products. The acid sites of SAPO-11 converted most levoglucosan produced from the non-catalytic pyrolysis of cellulose to furans. In particular, the selectivity toward light furans, such as furfural, furan and 2-methyl furan, was high. When the catalyst/ cellulose ratio was increased from 1/1 to 3/1 and 5/1, the increase in the quantity of acid sites led to the promotion of deoxygenation and the resultant increase of the contents of light furan compounds. Because furans can be used as basic feedstock materials, the augmentation of the economical value of bio-oil through the catalytic upgrading over SAPO-11 is considerable.
