Hydrothermal conversion of diatom frustules into barium titanate based replicas
… titanium dioxide replicas were subjected to a hydrothermal reaction by exposing the replicas to an aqueous basic solution containing barium hydroxide to form barium titanate and barium strontium titanate replicas. The effects of reaction temperature, time, and solution composition on extent of …

Investigation into the Hydrothermal Treatment of Sugarcane Bagasse under Near- and Supercritical Conditions
… of components. Very few studies of biomass hydrothermal conversion provide a comprehensive evaluation of multiple process parameters and various additives and their effects on a single product phase. This research examined the influence of temperature, residence time, biomass concentration, …

Hydrothermal Process for Bioenergy Production From Corn Fiber and Swine Manure
… fuels such hydrocarbons from thermochemical conversion of biomass have become potentially promising. This study aims at investigating the oil-formation mechanism during hydrothermal conversion of swine manure. For the purpose of mechanism research, a new method was developed first and …

Antimicrobial PLA and Calcium Phosphate Coatings and Thin Film Composites for Implants Applications
… (CaCO₃) was converted to HAp by using the hydrothermal conversion method. These microspheres were loaded with Gm and HAp-Gm particles and incorporated within the PLA thin film composites. Coralline-HAp possesses a unique nano- and meso-porous structure and can be used as a drug carrier for …

Computational fluid dynamics modeling of a continuous tubular hydrothermal liquefaction reactor
… dioxide capture, and wastewater treatment. Hydrothermal liquefaction (HTL) is the key component in the technology. It involves the conversion of biowaste and algae into hydrocarbon fuels at elevated temperature and pressure. However, E2-Energy is not yet commercially feasible due to a lack …

Improving algal biofuel production through nutrient recycling and characterization of photosynthetic anomalies in mutant algae species
… biomass production, wastewater treatment and conversion of biomass to bio-crude oil. In this system, low-lipid but fast-growing algae were cultivated in wastewater, and the biomass was harvested and fed into a hydrothermal liquefaction (HTL) process for biofuel production. The post-HTL …

Synthesis of zeolites from geological materials and industrial wastes for potential application in environmental problems
… by two different routes: (1) classic alkaline hydrothermal synthesis and (2) alkaline fusion prior to hydrothermal synthesis. In the first method, the synthesis of zeolitic materials was carried out generally in alkaline media, although KAO or its calcination product, metakaolinite (MTK), was …

Valorization of wastewater-derived biomass via integrated aqueous systems
… on developing integrated aqueous systems for conversion of wastewater-derived biomass into valuable products. The elimination of drying steps and reduction in solvent use make these processes ideal for processing wastewater-derived biomass, thereby enabling the simultaneous treatment and …

Characterizing the fate and transport of chemicals of emerging concern (CECs) from swine manure during waste to energy processes
… The resulting biomass was harvested for biofuel conversions via hydrothermal liquefaction (HTL) and catalytic hydrothermal gasification (CHG), which were performed under 16 different conditions to study the effects of hydrothermal processes on the removal of bioactive CECs. Solid Phase Extraction …
