Towards effective lignin conversion: HZSM-5 catalyzed one-pot solvolytic depolymerization/hydrodeoxygenation of lignin into value added compounds

A one-pot greener approach towards lignin depolymerization/hydrodeoxygenation is presented. Water was used as a reaction medium with methanol as a source of reductive equivalents of hydrogen in inert atmosphere. Zeolite HZSM-5 and Ni-doped HZSM-5 were synthesized at low temperature (95 degree C), ch...

Description
Summary:A one-pot greener approach towards lignin depolymerization/hydrodeoxygenation is presented. Water was used as a reaction medium with methanol as a source of reductive equivalents of hydrogen in inert atmosphere. Zeolite HZSM-5 and Ni-doped HZSM-5 were synthesized at low temperature (95 degree C), characterized and used as a hydrodeoxygenation catalyst at 220 degree C. Lignin conversion up to 96.8-98.5% was observed with highly reduced char formation (
