The thermochemical behavior of cellulose, glucomannan, and xylan was investigated by pyrolysis–gas chromatographymass spectrometry (Py-GC/MS). In each case, major GC-amenable condensable products were classified into several
compound groups, and the formation of these monomer-related fragments from the model substance samples was determined at 500, 600, and 700 C with a residence time of 5 s and 20 s. The results revealed that despite some general
formation trends, no compound group was selectively formed at certain temperatures. Of the 11 product groups, the
primary ones, including lactone, furan, and cyclopentenone derivatives, accounted for 72–85% (from cellulose), 86–90%
(from glucomannan), and 76–81% (from xylan) of the total amount of pyrolysis products determined. At 500 C, about half
of the major product groups accounted for lactones, such as 3-hydroxy-2-penteno-1,5-lactone and 5H-furan-2-one. It was
also confirmed by thermogravimetric analyses that within the temperature range studied, cellulose was thermally more
stable than the heterogeneous hemicelluloses. These kinds of data are of importance, for example, with respect to efforts to
develop new biorefinery possibilities for renewable resources.

Effects of pyrolysis temperature on the hydrologically relevant porosity of willow biochar
Hyväluoma, Jari; Hannula, Markus; Arstila, Kai; Wang, Hailong; Kulju, Sampo; Rasa, Kimmo (Elsevier BV, 2018)Biochar pore space consists of porosity of multiple length scales. In direct water holding applications like water storage for plant water uptake, the main interest is in micrometre-range porosity since these pores are ...
