Abstract: The present invention is related to biofuel oily suspensions that use biocarbon in their composition. In this scenario, the present invention provides a biofuel oily suspension, comprising 5 to 50% by weight of micronized biocarbon and 50 to 95% by weight of oil. The biofuel oily suspension of the present invention is better adapted to compression internal combustion engines (diesel type) currently on the market, dispensing with major adaptations to them. Furthermore, the biofuel oily suspension of the present invention is highly sustainable and has an energy volumetric density and viscosity compared to liquid fossil fuels currently on the market.

Abstract: The present invention is related to charge distribution systems in a metallurgical furnace. In this scenario, the present invention provides a load distribution system in a metallurgical furnace, comprising (i) an open silo (10) adapted to receive loads of different varieties, (ii) a closed silo (20) adapted to transfer loads from the open silo (10) to a sealed environment of the metallurgical furnace, (iii) at least one upper sealed valve (22), positioned upstream of the closed silo (20), (iv) at least one valve lower seal (24), positioned downstream of the closed silo (20), (v) at least two process silos (30), each process silo (30) adapted to receive a certain variety of load coming from the closed silo (20) and (vi) at least one distribution element (40) adapted to distribute the different load varieties in the respective process silos (30). The present invention also provides a method associated with the system described above.

Abstract: The present invention relates to a system for backmix the reagent mass in rotating cylindrical reactors. In this context, the present invention provides a system for internal backmix of the reagent mass in a rotating cylindrical reactor (2), comprising a first set of drag fins (27) adapted for dragging the reagent mass in a first direction, and a second set of drag fins (28) adapted for dragging the reagent mass in a second direction opposite to the first direction, wherein the first (27) and the second (28) set of drag fins are positioned internally along the length of the cylindrical rotating reactor (2). The system described above allows the mixing of a portion of the reagent mass at a more advanced stage of the reactor with another portion at an earlier stage of processing, homogenizing the reagent mass temperatures and increasing the reactor's productivity.

Abstract: The present invention relates to self-compensating thermal expansion sealing systems. In this context, the present invention provides a self-compensating thermal expansion sealing system for a cylindrical rotating reactor (2) comprising (a) a first self-compensating portion (8) positioned at a first end of the cylindrical rotating reactor (2), the first self-compensating portion (8) comprising (a.1) a guide ring (80) fixed to the support structure of the cylindrical rotating reactor (2), (a.2) an axially sliding housing ring (84) adjacent to the guide ring (80), the axially sliding housing ring (84) being sliding with respect to the guide ring (80) in the axial direction, and (a.

Abstract: The instant invention relates to a metallurgical furnace, comprising at least one upper stack (1), at least one lower stack (2), at least one fuel feeder positioned substantially between at least one upper stack (1) and the at least one lower stack (2), at least one row of tuyères (3, 4) positioned in at least one of the at least one upper stack (1) and at least one lower stack (2), the at least one row of tuyères (3, 4) providing a fluid communication between the inside of the furnace and the external environment, positioned in at least one of at least one upper stack (1) and at least one lower stack (2), and further comprising at least one permeabilizing fuel column fed through at least one hood (6), placed in the upper stack (1), which extends longitudinally through the furnace.

Abstract: The present invention pertains to metallurgical processes and equipment and, more particularly, to a metallurgical furnace capable of operating with a broad range of broad range of raw materials and fuels, including those with high levels of impurities. Accordingly, the metallurgical furnace of the present invention comprises (i) at least an upper tub, (ii) at least a lower tub, (iii) at least a fuel feeder positioned substantially between the at least an upper tub and the at least a lower tub, (iv) at least a row of tuyeres positioned on at least one of at least an upper tub and at least a lower tub, the at least a row of tuyeres fluidly communicating inside the furnace with the outside environment, and (v) at least a burner positioned on at least one of at least an upper tub and at least a lower tub. The use of at least a burner jointly with the at least a row of tuyeres generates a very intense release of heat by virtue of the exothermic reactions which occur by this combination.
