Abstract:
Die Vergasung von Biomasse mit überkritischem Wasser ist ein innovatives thermochemisches Verfahren, mit dem Biomasse bei hohen Temperaturen und Drücken in Wasser umgesetzt wird. Es eignet sich vor allem für die Verwertung wässriger Biomassen, die mit dem Verfahren bei kurzen Verweilzeiten und hohen Abbauraten effizient vergast werden können. In der Folge ergibt sich ein Produktgas, dessen Verstromung durch Wärme-Kraft-Maschinen möglich ist. Es wurde ein Prozess entwickelt, der die Technologie zur Verstromung feuchter Biomasse im kommerziellen Maßstab anwendbar macht.

Abstract:
Supercritical upgrading reactors and reactor systems for upgrading a petroleum-based compositions comprising one or more catalyst layers and, in some embodiments, one or more purging fluid inlets, where one or more catalyst layers at least partially sift and convert heavy hydrocarbon fractions to light hydrocarbon fractions to produce an upgraded supercritical reactor product. In some embodiments, upgrading reactor systems comprise one or more supercritical upgrading reactors and one or more supercritical standby reactors alternating functions such that a supercritical upgrading reactor is converted to a supercritical standby reactor and the supercritical standby reactor is converted to a supercritical upgrading reactor, where the supercritical upgrading reactor upgrades a combined feed stream while a supercritical standby reactor delivers a cleaning fluid into the supercritical standby reactor.
Abstract:
A lining particularly for performing oxidation processes and especially conventional and unconventional wet oxidation processes, which is substantially characterized by the presence of two separate portions, a first one made of titanium or alloys (11) thereof and a second one made of at least one nickel alloy (10). The two portions (10;11) of the lining are constituted by two layers, which are anchored on a substrate (14), generally steel, which is then shaped so as to provide the final apparatus. Advantageously, the apparatus is a wet oxidation reactor, plated internally with the lining as described above.

Abstract:
The invention discloses a method for producing bio-fuel (BF) from a high-viscosity biomass using thermo-chemical conversion of the biomass in a production line (10) with pumping means (PM), heating means (HM) and cooling means (CM). The method has the steps of 1) operating the pumping means, the heating means and the cooling means so that the production line is under supercritical fluid conditions (SCF) to induce biomass conversion in a conversion zone (CZ) within the production line, and 2) operating the pumping means so that at least part of the production line is in an oscillatory flow (OF) mode. The invention is advantageous for providing an improved method for producing biofuel from a high-viscosity biomass. This is performed by an advantageous combination of two operating modes: supercritical fluid (SCF) conditions and oscillatory flow (OF).
Abstract:
An improved processing technique that can be used to collect nanoparticles produced by the RESS process. The collection efficiency by almost an order of magnitude compared to the traditional collection processes. One process does not utilize any stabilizing solid co-solvents but produces similar effects using the supercritical solvent itself (e.g. CO2) as a stabilizing phase. Very small particles (diameter
