As a result of algae's promise as renewable energy feedstock, numerous studies have used Life Cycle Assessment (LCA) to quantify the environmental performance algal biofuels, yet there is no consensus results among them. Our work, motivated by lack comprehensive uncertainty analysis in previous studies, uses Monte Carlo approach estimate ranges expected values LCA metrics incorporating parameter variability with empirically specified distribution functions. Results show that large...
Within the framework of a proposed two-step mechanism for hydrate inhibition, energy binding four inhibitor molecules (PEO, PVP, PVCap, and VIMA) to surface is estimated with molecular dynamic simulations. One key feature this that an molecule ensuing crystal disrupts growth therein crystallization. It found through simulations experimentally exhibit better inhibition strength also have higher free energies binding, indirect confirmation our mechanism. Inhibitors increasing in effectiveness,...

Kinetic and mechanistic evidence is presented of the occurrence a Maillard-type reaction under conditions interest to hydrothermal biomass processing. Glucose−glycine mixtures were reacted at 250 °C 10 MPa in an excess water; both glucose glycine found strongly influence destruction kinetics other species result quantitative qualitative changes, such as strong absorbance 420 nm production dark brown appearance nutty odor, which are characteristic Maillard reaction. The presence always...

The objective of this study was to elucidate the effect adding acid and alkali hydrothermal liquefaction (HTL) two waste biomass feedstocks: manure digestate carbohydrate-rich food waste. HTL reactions were conducted at 300 °C for 60 min, with without addition or base. We measured quantity characterized quality three main products: oil, aqueous hydro-char. For both feedstocks, carbon recovery distributions had wide ranges among (1) biocrude oil (26–61 wt %), (2) product (9–49 %) (3)...
Abstract Glucose hydrolysis and oxidation occurred rapidly in supercritical water at 246 bar 425 to 600°C. A diverse set of products, present the liquid‐phase reactor effluent also subject hydrolysis, was formed. At 600°C a 6‐s residence time, glucose is completely gasified, even absence oxygen. In presence oxygen, destruction products enhanced, with none found above 550°C time. Major formed wee acetic acid, acetonylacetone, propenoic acetaldehyde liquid phase, carbon monoxide, dioxide,...
