The biological pretreatment of wood biomass for degrading lignin, a complex aromatic polymer, has received much attention as an environmentally safe or “green” process. Generally, enzymes isolated from naturally occurring fungi, or with enzymes produced by genetically engineered fungi have been...

In an effort developing more efficient and environmentally benign lignocellulosic biomass processing technologies, the authors’ laboratory has been studying plant cell wall degradation process in termite and white-rot fungi. This presentation summarizes the results so far obtained from various...

Chemical looping process is effective in converting carbonaceous fuels into hydrogen and electricity while generating a sequestration-ready CO 2 stream. The process scheme is enabled by the cyclic reduction and oxidation reactions of an oxygen carrier (OC). The properties of OCs are of critically...

Catalytic study on lignin degradation and conversion into biofuels Wei Mu and Yulin Deng School of Chemical and Biomolecular Engineering and IPST at GT, Georgia Institute of Technology, Atlanta, Georgia 30332-0620 Author for correspondence (e-mail: yulin.deng@chbe.gatech.edu ) As an ideal...

Lignocellulosic biorefineries require an efficient system of biomass storage between harvesting and processing. This study reports the effect of storage method and duration on the composition and processing performance of sweet sorghum bagasse. Sorghum bagasse was harvested at 85% moisture content...

Dilute-acid pretreatment is one of the most advanced and widely accepted pretreatment technologies. In this study, improvement in the process was sought specifically in the area of reactor technology. NREL has developed an efficient continuous pretreatment reactor that can be operated with high-...

Plant lignin is a source of useful chemicals, and also the major barrier for saccharification of lignocellulosic biomass for ethanol conversion. The enzymatic lignin degradation/modification could bypass the need for chemical pretreatment and thereby facilitate bioprocess consolidation. Herein, we...

The current vision of biomass (e.g. plant, algae) conversion technologies is focused on developing the reactive intermediates platform for biofuels and chemicals production. A key challenge in using biomass as a renewable resource is its incredibly diverse polymeric structure. Sugars, furfural, HMF...

The University of Kentucky, Center for Applied Energy Research is investigating oxygen carriers (OC) for chemical looping combustion (CLC) with the goal of developing a pressurized chemical looping combustion/gasification process for generating electricity from coal. An important issue in the...

The pyrolytic conversion of biomass to into liquid fuels has the potential to become drop-in transportation fuels if some of its negative attributes such as high total acid number (TAN), high viscosity, and poor storage stability are overcome. We investigated nickel phosphide supported on fluid...
