Journal ArticleDOI
Effects of alkaline or liquid-ammonia treatment on crystalline cellulose: changes in crystalline structure and effects on enzymatic digestibility.
TL;DR: It is found that the chemical treatments to produce different allomorphs also changed the crystallinity of the cellulose, and this had a significant effect on the digestibility of the substrate.
Journal ArticleDOI
Reductive Catalytic Fractionation of Corn Stover Lignin
Eric M. Anderson,Eric M. Anderson,Rui Katahira,Michelle Reed,Michael G. Resch,Eric M. Karp,Gregg T. Beckham,Yuriy Román-Leshkov +7 more
TL;DR: In this article, the authors investigate the RCF of corn stover, a highly abundant herbaceous feedstock, using carbon-supported Ru and Ni catalysts at 200 and 250 °C in methanol and, in the presence or absence of an acid cocatalyst (H3PO4 or an acidified carbon support).
Journal ArticleDOI
Flowthrough Reductive Catalytic Fractionation of Biomass
Eric M. Anderson,Michael L. Stone,Rui Katahira,Michelle Reed,Gregg T. Beckham,Yuriy Román-Leshkov +5 more
TL;DR: In this article, a flow-through RCF was used to investigate RCF of poplar, showing that leaching, sintering, and surface poisoning are causes for decreased catalyst performance.
Journal ArticleDOI
Base-Catalyzed Depolymerization of Biorefinery Lignins
Rui Katahira,Ashutosh Mittal,Kellene McKinney,Xiaowen Chen,Melvin P. Tucker,David K. Johnson,Gregg T. Beckham +6 more
TL;DR: BCD is applied with sodium hydroxide at two catalyst loadings and temperatures of 270, 300, and 330 °C for 40 min to residual biomass from typical and emerging biochemical conversion processes to gain insights in the application of BCD to lignin-rich, biofuels-relevant residues.
Journal ArticleDOI
Lignin depolymerisation by nickel supported layered-double hydroxide catalysts

TL;DR: In this paper, a 5% Ni-HTC catalyst was used to depolymerise two types of biomass-derived lignin, which produces alkyl-aromatic products.
