Hydrothermal liquefaction (HTL) is a viable thermochemical process for converting wet solid wastes into biocrude that can be hydroprocessed to liquid transportation fuel blendstocks and specialty chemicals. The aqueous byproduct from HTL contains significant amounts (20–50%) of the biogenic feed carbon, which must valorized enhance economic sustainability on an industrial scale. In this study, fractions produced food industry wastes, municipal biomass cultivated wastewater were characterized...
Feedstock composition can affect final fuel yields and quality for the fast pyrolysis hydrotreatment upgrading pathway. However, previous studies have focused on individual unit operations rather than integrated system. In this study, a suite of six pure lignocellulosic feedstocks (clean (no bark) pine, whole-tree (including tulip poplar, hybrid switchgrass, corn stover) two blends (equal weight percentages pine/tulip poplar/switchgrass pine/clean pine/hybrid poplar) were prepared...
Two-dimensional gas chromatography coupled with time-of-flight mass spectrometry is a powerful tool for identifying and quantifying chemical components in complex mixtures. It often used to analyze gasoline, jet fuel, diesel, bio-diesel the organic fraction of bio-crude/bio-oil. In most those analyses, first dimension separation non-polar, followed by polar separation. The aqueous fractions bio-crude other samples from biofuels production have been examined similar column combinations....
We preview two processes that facilitate using formic acid (HCOOH) as a liquid hydrogen carrier to store renewably-generated electrical energy and then release it generate power cleanly for backup or emergency applications. First, we show simultaneously oxidizing an organic solute (typically waste stream) can assist the electrochemical synthesis of by lowering cell potential. The electrolyser comprises hybrid 3-chamber PEM stack reduces CO₂ via gas-diffusion cathode boosted oxidation aqueous...
This research investigates the bed agglomeration phenomena during steam gasification of a high-lignin residue produced from simultaneous saccharification and fermentation (SSF) corn stover in bubbling fluidized bed. The studies were conducted at 895 °C using alumina as material. Biomass was fed 1.5 kg/h, while to give velocity equal 2.5 times minimum fluidization velocity, with steam/carbon ratio 0.9. pelletized feedstock co-fed cooling nitrogen stream mitigate feed line plugging issues. Tar...
