A flow reactor comprising: a cylindrical body defining a conduit extending from a first end to a second end; a conduit inlet for providing a flow of a liquid reagent into the conduit, the conduit inlet at or near the first end; a conduit outlet for providing a flow of a liquid content from the conduit, the conduit outlet at or near the second end; a rotating screw arranged within the conduit and extending in the conduit, the rotating screw arranged to rotate about an axis extending from the first end to the second end, to direct the liquid content from the conduit inlet to the conduit outlet; and one or more ultrasonic emitters arranged to emit ultrasound waves in the conduit. The flow reactor may be used for desulphurization of fuel oil.

The invention relates to an apparatus (1) for processing a slurry containing organic components, such as biomass, having a water contents of at least 50%, comprising a heat exchanger (7) to heat the slurry and a reactor (8) to convert at least a part of the organic components in the slurry, wherein at least one of the heat exchanger (7) and the reactor (8) comprises one or more pipes (7A; 8A). At least one transport screw (15) is accommodated in the pipe (7A; 8A) or at least one of the pipes (7A; 8A).

An entirely water-based, energy self-sufficient, integrated in-line waste management system is provided for comprehensive conversion of all organic fractions of municipal and wider community waste to fuels suitable for use in transportation, with all solid residues converted to high nutrition compost. The system is based on a combination of pre-treatment, involving alkaline hydrolysis and saponification; three-way separation of the pre-treated waste into different streams that are each directed to suitable further processing including fuel production; which includes biodiesel generation in a continuous-flow catalytic esterification unit, and anaerobic digestion to produce methane or other small molecule biofuel. Remaining solids are converted to compost in a quasi-continuous process.

Systems, methods and apparatus for the thermal conversion of biomass into biochar. A mobile platform may be used to maneuver a mobile biochar generation system within a field of biomass. The biomass may be harvested, preprocessed and pyrolyzed. After pyrolyzation, the biochar may be cooled to a predetermined temperature by integrating water and liquid nutrients into the biochar. The system may then control the application of the infused biochar by adjusting a spreading attachment and a plowing attachment.

Devices and methods for the high-pressure treatment of bulk material by extraction and/or impregnation. The bulk material is arranged in the interior volume of a pressure vessel device and is treated at a high pressure while sealed off from the surroundings. The high-pressure treatment is performed batchwise in a closed system in the pressure vessel device in a pressure-tight fashion. The bulk material is fed batchwise to the interior volume with the pressure vessel device closed and being arranged on at least one treatment level and, after the high-pressure treatment has occurred, being discharged batchwise from the interior volume with the pressure vessel device closed. The invention furthermore relates to the use of a supporting tray module with at least one treatment level for the high-pressure treatment in a closed system.
