Characterization of Hydrotreated Fast Pyrolysis Liquids

Energy & Fuels, 2010
This paper focuses on analytical methods to determine the composition of hydrotreated fast pyrolysis liquids. With this information, it is possible to gain insights in the chemical transformations taking place during catalytic hydrotreatment (hydrogenation and/or hydrodeoxygenation, HDO) of pyrolysis liquids.

Fast Pyrolysis of Şırnak Asphaltite (Turkey) and Characterization of Pyrolysis Products

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2008
Abstract Fast pyrolysis of Sirnak Asphaltite (SASP) was investigated to determine yield and distribution of volatile products at different temperatures. A special sampling technique was used for collecting organic products formed at different time intervals and pyrolysis temperatures.

Insight into the formation mechanism of levoglucosenone in phosphoric acid-catalyzed fast pyrolysis of cellulose

Journal of Energy Chemistry, 2020
The catalytic fast pyrolysis of cellulose impregnated with phosphoric acid (H3PO4) offers a promising method for the selective production of levoglucosenone (LGO), a valuable anhydrosugar product.

Fast pyrolysis of plastic wastes

Energy & Fuels, 1990
Preliminary results using an atmospheric-pressure fluidized-bed fast pyrolysis process have been obtained for the fast pyrolysis of commercial grades of polystyrene, poly(vinyl chloride), and polyethylene. On the basis of these tests, polyethylene was selected for detailed study because of the difficulty in regenerating the monomer in good yields and ...

Ex-situ catalytic fast pyrolysis of soapstock for aromatic oil over microwave-driven HZSM-5@SiC ceramic foam

, 2020
In view of the poor selectivity of aromatic hydrocarbons in bio-oil from biomass pyrolysis and the high pressure drop and rapid coking and deactivation of catalyst in industrial scale, a microwave-driven HZSM-5@SiC ceramic foam has been constructed, and ...

Fast Pyrolysis of Cellulose, Hemicellulose, and Lignin: Effect of Operating Temperature on Bio-oil Yield and Composition and Insights into the Intrinsic Pyrolysis Chemistry

Industrial & Engineering Chemistry Research, 2019
Fast pyrolysis of biomass produces bio-oil as a dominant product. However, the yield and composition of bio-oil are governed by numerous pyrolysis reactions which are difficult to understand because of the multiphase decomposition phenomena with ...

Fast Pyrolysis of Biomass

1988
Pyrolysis Gas Chromatography (PGC) was used to study the devolatilization of wood under conditions of high heating rates, short residence times, high temperature and rapid-quenching. A new technique of placing the sample in the pyroprobe was used which minimized resistance of heat transfer to the sample and ensured immediate quenching of the primary ...

Fast pyrolysis (ultrapyrolysis) of cellulose

Journal of Analytical and Applied Pyrolysis, 1984
Abstract A fast pyrolysis process, termed ultrapyrolysis, has been developed at the University of Western Ontario in order to exploit the high heating rates, short residence times high temperatures and rapid quenching, which are required to produce valuable non-equilibrium intermediates (i.e. ethylene and acetylene) from finely divided biomass.
