LIGNIN TO CHEMICALS AND HYDROGEN

摘要

1. Combined lignin depolymerization and hydrogen production by a novel PEM electrolysis process 2. -14% of Kraft lignin was converted to aromatic chemicals (GPC GC-MS) and the changes of lignin structures were characterized by 2D HSQC, ~(31)P NMR. FTIR and XPS 3. Noble metal catalyst at anode of conventional PEM electrolyzer was replaced by graphite 4. Faraday efficiency was higher than 90%; Saved more than 40% electric energy comparing with the best alkaline water electrolysis
