Production of Renewable Aromatic Compounds by Catalytic Fast Pyrolysis of Lignocellulosic Biomass with Bifunctional Ga/ZSM-5 Catalysts
Open accessAbstract
Burn, baby, burn! A new bifunctional catalyst (Ga/ZSM-5) displays increased selectivity for the production of aromatic compounds during the catalytic fast pyrolysis of biomass. With this Ga-promoted ZSM-5 catalyst, olefins such as ethylene and propylene, which are produced as intermediates, are more efficiently converted into aromatic compounds, especially benzene. Ga/ZSM-5 also promotes decarbonylation and olefin-aromatization reactions.

Gallium impregnation affects the Brønsted acidity of the catalysts and is known to promote deoxygenation/decarbonylation of phenols and aromatization of aliphatics/olefins.
“The impregnation of the catalysts with gallium not only effects the Bronsted acidity of the catalysts but it is also known that it positively influences the deoxygenation/decarbonylation of phenols and is able to aromatize aliphatics/olefins, in our case originating from remaining carbohydrates and the aliphatic backbone of the lignin framework of black liquor.36”
From Synthesis of Bio-aromatics from Black Liquors Using Catalytic Pyrolysis. (2018) · cites this paper as [36]
In the catalyst-characterization discussion (page unavailable), the paper reports that increasing Ga content lowers the ratio of Brønsted to total acid sites. Its furan-conversion results say Ga promotes furan decarbonylation and olefin aromatization, and its background discussion notes alkane aromatization. It does not establish that Ga promotes deoxygenation or decarbonylation of phenols; phenol appears as a product in the pinewood results, not as a tested feedstock. (LLM, conf=0.87)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
