Feedstock recalcitrance is the most important barrier impeding cost-effective production of cellulosic biofuels. Pioneer commercial ethanol facilities employ thermochemical pretreatment and addition fungal cellulase, reflecting main research emphasis in field. However, it has been suggested that may be possible to process biomass without using thermophilic, cellulolytic bacteria. To further explore this idea, we examine ability various biocatalysts solubilize autoclaved but otherwise...

During gasification, thermally pretreated biomass and <italic>in situ</italic> catalyst yield different carbon conversion efficiencies, though they both reduce tar.
Biomass pyrolysis offers a promising means to rapidly depolymerize lignocellulosic biomass for subsequent catalytic upgrading renewable fuels. Substantial efforts are currently ongoing optimize processes including various fast and schemes. In all cases, complex aqueous streams generated containing solubilized organic compounds that not converted target fuels or chemicals often slated wastewater treatment, in turn creating an economic burden on the biorefinery. Valorization of species these...
During biomass gasification, sulfur contained in the feedstock is converted primarily to hydrogen sulfide. Conventional technologies for removal such as amine scrubbing and ZnO sorption operate at much lower temperatures than those of gasification tar reforming are thus thermally inefficient cleanup biomass-derived syngas. This work aims develop options high-temperature removal. In this research, we focus our investigation on regeneration chemistry a manganese-based sorbent high temperature,...
Phenol-formaldehyde resins are major material classes that used in a range of applications including composites, adhesives, foams, electronics, and insulation. While efforts have been made to produce renewable resins, there has yet be an approach offers potential for economic viability meets all critical quality metrics. This failure can attributed largely the use phenol cresol homologues high separation costs. In this work, phenol, cresol, alkyl phenols derived from aqueous phase generated...
We investigate and quantitate the changes in hydrocarbon product composition while evaluating performance operability of National Renewable Energy Laboratory's Davison Circulating Riser (DCR) reactor system when biomass model compounds are cofed with traditional fluid catalyst cracking (FCC) feeds catalyst: vacuum gas oil (VGO) equilibrium zeolite (E-Cat). Three (acetic acid, guaiacol, sorbitan monooleate) were selected to represent major classes oxygenates present pyrolysis vapors. These...
Demand for the development of an automated and integrated refining process biofuels has increased in recent years due to lack generalized inspection tools. In bio-oil upgrading processes, all variables are maintained based on offline specification intermediates products. A real-time product specifications batch-wise monitoring can cause failure wasted resources. Therefore, there is a need fast accurate intermediates/product tool that be used reduce waste mitigate risk failure. To address...
