DOI: 10.1021/acs.energyfuels.7b01490
Abstract: Lignin pyrolyses and in situ hydrodeoxygenation over MoO3 with varying lignin/MoO3 mass ratios (L/M) at different temperatures were studied in a free-falling reactor. The presence of MoO3 not only facilitated the depolymerization of lignin to… read more here.

DOI: 10.15376/biores.15.2.3356-3367
Abstract: The pyrolysis processes of lignin under the action of CaO and K2HPO4·3H2O alone or in coordination were studied by thermogravimetric mass spectrometry (TG-MS). The experimental results showed that after addition of CaO, CaO immobilized the… read more here.
