“…The pyrolysis characteristics of the biomass constituents (cellulose, hemicellulose and lignin) have also been investigated during the recent few years. 17,18 For example, classical simple conversion mechanism was suggested for the pyrolysis of cellulose. 19 According to this mechanism, at first, cellulose is converted to active cellulose (intermediate species) without mass reduction.…”

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.

“…Carbohydrates, such as levoglucosan are converted to furans in the presence of an acid catalyst, such as SAPO-11, due to an enhanced dehydration reaction. 17 The furan yield was highest when the biomass/catalyst ratio was 1:1. The furan yield decreased when the catalyst dose was doubled, possibly due to the enhanced conversion of furans to aromatics.…”

“…This was attributed to the enhanced cracking by SAPO-11. Jeon et al 17 who examined the catalytic pyrolysis of cellulose, also reported that highmolecular-mass furans were converted to low-molecular-mass furans under increasing Al-SBA-15 catalyst dose. Because furans, particularly low-molecular-mass furans (e.g.…”

SAPO-11 was applied for the first time to the catalytic pyrolysis of miscanthus and random polypropylene (random PP). Thermogravimetric analysis confirmed that SAPO-11 promoted the dehydration of miscanthus while suppressing the formation of char. In the pyrolysis of random PP, the decomposition temperature and activation energy were reduced by using a catalyst. A large fraction of levoglucosan, which was the main oxygenate product from the non-catalytic pyrolysis of miscanthus, was converted to high value-added products, such as furans, phenolics and aromatics using SAPO-34. The catalytic pyrolysis of random PP produced gasoline-and diesel-range hydrocarbons.

“…In the present study, much less phenolics with methoxy group were produced from the catalytic pyrolysis over Al-MCM-48 because Al-MCM-48 promoted the demethoxylation of phenolics. Jeon et al 13 reported that the demethoxylation of phenolics produced from lignin was enhanced by acid catalysts. The effects of Al containing mesoporous catalysts on promoting decarbonylation and decarboxylation of phenolics were suggested.…”

“…The effects of Al containing mesoporous catalysts on promoting decarbonylation and decarboxylation of phenolics were suggested. 13,16 From the above papers, it could be inferred that Al-MCM-48 could promote the deoxygenation (decarbonylation and decarboxylation), demethoxylation, and aromatization of phenolics. This also implied that more stable bio-oil with a lower content of oxygen could be produced using Al-MCM-48 rather than Si-MCM-48.…”

Catalytic pyrolysis of Geodae-Uksae 1, a kind of miscanthus found in Korea, was carried out over mesoporous MCM-48 catalysts. For rapid product analysis and catalyst evaluation, pyrolysis-gas chromatography/mass spectrometry was used. X-ray diffraction, nitrogen sorption, pyridine adsorbed Fourier transform infrared, and NH3 temperature programmed desorption were utilized to analyze the properties of the catalysts. Compared to non-catalytic reaction, catalytic upgrading over mesoporous Al-MCM-48 catalysts produced a higher-quality bio-oil with a high stability and low oxygen content. Al-MCM-48 exhibited higher deoxygenation ability than Si-MCM-48 due to its higher acidity.
