Estimation of lignocellulosic biomass pyrolysis product yields using artificial neural networks

As the push towards more sustainable ways to produce energy and chemicals intensifies, efforts are needed to refine and optimize the systems that can give an answer to these needs. In the present work, the use of neural networks as modelling tools for lignocellulosic biomass pyrolysis main products yields estimation was evaluated. In order to...

Biomass pyrolysis TGA assessment with an international round robin

The large variations found in literature for the activation energy values of main biomass compounds (cellulose, hemicellulose and lignin) in pyrolysis TGA raise concerns regarding the reliability of both the experimental and the modelling side of the performed works. In this work, an international round robin has been conducted by 7 partners...

PAH sampling and quantification from woody biomass fast pyrolysis in a pyroprobe reactor with a modified tar sampling system

The present work focuses on the sampling procedure and quantification of the PAH yield from the fast pyrolysis of waste softwood. In particular, fast pyrolysis experiments were conducted using a CDS Pyroprobe 5200 at temperatures between 500 °C and 1000 °C, at a heating rate of 600 °C/s for a sample size of 30 mg. High performance liquid...

Investigation of poultry litter conversion into useful energy resources using fast pyrolysis

The present study explored a thermochemical treatment method as an alternative approach to process animal feedlot (poultry litter). Fast pyrolysis of poultry litter experiments was conducted using a Pyroprobe 5200 reactor in the temperature range of 400-600 °C. The influence of reactor temperature on the yield of pyrolytic gases, condensate ...
