Fast Pyrolysis of Cellulose by Infrared Heating

Cellulose–Hemicellulose and Cellulose–Lignin Interactions during Fast Pyrolysis

Previously, the primary product distribution resulting from fast pyrolysis of cellulose, hemicellulose, and lignin was quantified. This study extends the analysis to the examinations of interactions between cellulose−hemicellulose and cellulose−lignin, which were determined by comparing the pyrolysis products from their native mixture, physical mixture, and superposition of individual component...

A reactor for high-temperature pyrolysis and oxygen isotopic analysis of cellulose via induction heating.

A reactor for converting cellulose into carbon monoxide for subsequent oxygen isotopic analysis via continuous flow isotope ratio mass spectrometry is described. The system employs an induction heater to produce temperatures >or=1500 degrees C within a molybdenum foil crucible positioned by boron nitride (BN) spacers within a quartz outer sleeve. For samples of a homogeneous working standard ce...

Microwave Heating Applied to Pyrolysis

Fast Pyrolysis of Lignins

Three lignins: Indulin AT, Lignoboost, and Acetocell lignin, were characterized and pyrolyzed in a continuous-fed fast pyrolysis process. The physical and chemical properties of the lignins included chemical composition, heat content, ash, and water content. The distributed activation energy model (DAEM) was used to describe the pyrolysis of each lignin. Activation energy distributions of each ...

Quantitative Insights into the Fast Pyrolysis of Extracted Cellulose, Hemicelluloses, and Lignin

The transformation of lignocellulosic biomass into bio-based commodity chemicals is technically possible. Among thermochemical processes, fast pyrolysis, a relatively mature technology that has now reached a commercial level, produces a high yield of an organic-rich liquid stream. Despite recent efforts to elucidate the degradation paths of biomass during pyrolysis, the selectivity and recovery...
