“…Here, the term "bioeconomy" refers to the "sustainable production and conversion of plants into food, fibers, health and industrial products, and energy" ). Biomass-derived fuels have potentials as viable alternatives to petroleum-based fuels in the short to medium terms (Prado et al, 2016). Several techniques have been designed and evaluated for the recovery of bioactive compounds and sugars from natural feedstocks and to produce biogas, biohythane, or valuable carbonized solids from different types of biomass.…”

Biofuel Research Journal 14 (2017) HIGHLIGHTSØAdvances of research trends in development of subcritical and supercritical water processes technologies are reviewed.Essential aspects of sub-and supercritical water applied to extraction, hydrolysis, carbonization and gasification processes are discussed. ØEquipment design, process parameters, and types of biomass used for sub-and supercritical water process are presented.

This review summarizes the recent essential aspects of subcritical and supercritical water technology applied to the extraction, hydrolysis, carbonization, and gasification processes. These are clean and fast technologies which do not need pretreatment, require less reaction time, generate less corrosion and residues, do not use toxic solvents, and reduce the synthesis of degradation byproducts. The equipment design, process parameters, and types of biomass used for subcritical and supercritical water process are presented. The benefits of catalysis to improve process efficiency are addressed. Bioactive compounds, reducing sugars, hydrogen, biodiesel, and hydrothermal char are the final products of subcritical and supercritical water processes. The present review also revisits advances of the research trends in the development of subcritical and supercritical water process technologies. GRAPHICAL ABSTRACT ARTICLE INFO ABSTRACT

“…SCW properties have been acknowledged as the reasons for utilization of SCW in various organic reactions and processes. 3,32 Although deemed as physical terms, those properties may affect chemical reaction, especially on the generation of acid-base catalyst and miscibility of aqueous-organic phases. In this study, the effect of SCW properties were measured statistically by correlation constant to observe uctuation of measurable production parameters (i.e., FA yield and Cu removal) with respect to SCW properties.…”

Abstract.One of the negative effects of the continuous development of civilization which is observed in recent decades is an increase in the number and variety of pollutants released into the environment. These substances have ecotoxic properties and pose a serious threat to humans and proper functioning of the ecosystem. Their presence in the environment forces the development of new pollution control techniques. One of the latest and very promising methods to destroy organic contaminants using the properties of water which exceeded the critical point is thermohydrolysis in supercritical water. The aim of this study was to investigate thermohydrolysis in supercritical water conditions and to check its suitability for removal of hardly biodegradable organic compounds present in wastewater. Tests for toxicity of these compounds to aquatic organisms such as sewage bacteria, crustaceans and guppy fish were also performed and the degree of their biological decomposition was determined. Biological studies were carried out on starting compounds and after the processes of thermohydrolysis. The research material included p-nitrotoluene sulfonic acid (PNTS), 4,4'-dinitrostilbene-2,2'-disulfonic acid (DNSDS) and 4,4'-diaminostilbene-2,2'-disulfonic acid (DASDS). The research leads to the conclusion that the reactions occurring during hightemperature thermohydrolysis of the three tested compounds are extremely complex. Results of biological studies indicate a significant decrease in toxicity and increase in the biodegradability of products obtained after the process of thermohydrolysis.
