Catalytic depolymerization of Kraft lignin to high yield alkylated-phenols over CoMo/SBA-15 catalyst in supercritical ethanol

Abstract

Kraft lignin was subjected to CoMo/SBA-15 catalyst in supercritical ethanol for high yield of alkylated-phenolic monomers production.

Enhanced activity of Co–Mo–S catalysts towards hydrodesulfurization and hydrogen evolution reaction via NaBH4 assisted formation

“…11–18 Considering that HDS and HER involve hydrogenation and dehydrogenation processes, which are inverse reactions, the activity and correlation of Co–Mo–S based catalysts between these two reactions are worthy of in-depth investigation. 19,20…”

“…[11][12][13][14][15][16][17][18] Considering that HDS and HER involve hydrogenation and dehydrogenation processes, which are inverse reactions, the activity and correlation of Co-Mo-S based catalysts between these two reactions are worthy of indepth investigation. 19,20 It has been found that the size, morphology and structure of MoS 2 have a certain correlation with its catalytic activity. 21,22 Studies have shown that the Co promotes MoS 2 based catalysts which have high performance for HER, are also active for HDS.…”
