Hydrothermal processing of biogenic residues in Germany
The mining, processing, and use of finite natural resources is associated with significant interventions in the natural environment. Thus, these and other negative consequences make it necessary to reduce resource consumption. An important field of action is the more efficient use of biogenic …

Hydrothermal processing of high-lipid biomass to fuels
… be dewatered significantly to form biofuels. A hydrothermal environment, utilizing a highpressure, high-temperature, water-based medium, is well-suited for processing these dilute biomass feedstocks. Conversion of high-lipid model feedstocks to bio-crude oils was investigated over temperatures …

Characterization of particles created by laser-driven hydrothermal processing
… study examined particles created by laser-driven hydrothermal processing, an innovative technique used for the ablation of submerged materials. Two naturally occurring materials, obsidian and tektite, were used as targets for this technique. Characterization of sample materials before and after …

Hydrothermal Processing of Barium Strontium Titanate Composites on Printed Circuit Board for Thin Film Varactor Applications
… Sol-gel derived powders are very reactive to the hydrothermal process. The resultant film permittivity is the highest, ranging from 200 to 260, but with a limited tunability of 1%. Ceramic derived powders are compatible with the process. The permittivity is less than that of sol-gel derived, with …

Hydrothermal liquefaction of wild-harvested cyanobacterial bloom from hypereutrophic Lake Tainter, Wisconsin
… (HABs) as a feedstock for generating biofuels hydrothermal liquefaction (HTL) and asserts that HTL is a uniquely practical technology for use of this biohazardous material. Using a wild-harvested cyanobacteria HAB from Lake Tainter, Wisconsin as a low-cost feedstock for HTL, the projected …

Hydrothermal Process of Swine Manure to Oil Using a Continuous Reactor System
Hydrothermal processing of swine manure is a novel technology that has shown very promising results in treating waste and producing oil. Oil yields of up to 70% were achieved in batch experiments. Since a continuous-mode process is more applicable for scale-up operations, a continuous hydrothermal …

Synthesis and characterisation of metal oxides and metal doped variants
… which remains stable to 900°C. <br></br><br></br>Hydrothermal synthesis of zirconium(IV) oxide from a solution of ziroconium(IV) acetate produces a mixture of tetragonal- and monoclinic- zirconia. Increasing the calcination temperature induces a transformation to the monoclinic polymorph. Addition …

Hydrothermal liquefaction for energy recovery from high-moisture waste biomass
Hydrothermal liquefaction is promising technology for converting high-moisture waste biomass into energy dense “biocrude” oil that can be used for direct combustion or refined for transportation grade fuels. This study investigates the influence of biomass composition on the chemical …
