Abstract: An apparatus for preparing a water/diesel oil micro-emulsion comprises a mixing device operatively connected to a mixing tank. The mixing device comprises a cone shaped septum placed in a duct, coaxial with respect to a main direction and tapering towards an outlet nozzle. The cone shaped septum is provided with a plurality of holes made through its conical wall. A plurality of lamellae is arranged in at least a portion of the duct placed downstream of the cone shaped septum, divides the portion in a plurality of small chambers and is provided with through holes. The holes and the small chambers delimit a labyrinth passageway for the liquid flowing through the duct towards the outlet nozzle.

Abstract: A method for producing biomass derived liquid, comprises: feeding biomass, a solvent and a catalyst into a batch reactor, and heating and mixing in the batch reactor a compound comprising the biomass, solvent, and catalyst. The solvent is glycerol and wherein feeding the solvent into the batch reactor is performed through electrostatic atomization.

Abstract: A water in diesel oil fuel micro-emulsion for internal combustion diesel engines, with a low content of surfactants, a very long shelf-life, a reduced production of pollutants and carbonaceous side-products generated by the combustion and very good engine performance, is described. These emulsions comply with the strict requirements of Italian regulations and are particularly useful as fuels for automotive and heating applications.

Abstract: An apparatus for preparing a water/diesel oil micro-emulsion comprises a diesel oil feeding unit (2), an emulsifying composition feeding unit (3), a water feeding unit (4), a mixing tank (5) in fluid communication with the diesel oil feeding unit (2), with the emulsifying composition feeding unit (3) and with the water feeding unit (4). A mixing device (22) is operatively connected to the mixing tank (5). The mixing device (22) comprises a duct (39) extending along a main direction (X-X) and presenting an inlet opening (40) and an outlet nozzle (41). A cone shaped septum (60) is placed in the duct (39), coaxial with respect to the main direction (X-X) and tapering towards the outlet nozzle (41). The cone shaped septum (60) is provided with a plurality of holes (65) made through its conical wall (63). A plurality of lamellae (76, 80) are arranged in at least a portion of the duct (39) placed downstream of the cone shaped septum (60).
