Abstract: Amine compounds having activity against inflammation, fungi, unicellular parasitic microorganisms, and cancer are described. The compounds contain a monocyclic, bicyclic, or tricyclic aromatic ring having one, two, or three ring nitrogen atoms.

Abstract: A method of operating a network of plants comprising a blast furnace, a direct reduction furnace, a CO2 conversion unit wherein blast furnace top gas is subjected to a CO2 conversion step to produce a liquid carbon product which is injected into the direct reduction furnace.

Abstract: A method for manufacturing direct reduced iron wherein oxidized iron is reduced in a direct reduction furnace by a reducing gas, the direct reduction furnace including a reduction zone, a transition zone and a cooling zone, a carbon-bearing liquid being injected below the reduction zone.

Abstract: A method for manufacturing direct reduced iron wherein oxidized iron is reduced in a direct reduction furnace by a reducing gas, the oxidized iron being first mixed with biochar to form a solid compound and the solid compound is charged into the direct reduction furnace.

Abstract: A method for manufacturing direct reduced iron wherein iron ore is reduced in a direct reduction furnace by a reducing gas, the reducing gas exiting the furnace through the top as a top reduction gas. The top reduction gas is captured and at least partly subjected to a CO2 recovery step during which it is divided into two streams, a CO2-rich stream and a CO2-poor stream. The CO2-rich stream is subjected to an alkanol production step to produce an alkanol product.

Abstract: A method for manufacturing Direct Reduced Iron wherein iron ore is reduced in a DRI shaft by a reducing gas including hydrogen obtained by extraction from coke oven gas through a hydrogen separation unit, the remaining part of such coke oven gas being at least partly injected in the transition section of said DRI shaft to set the carbon amount of said Direct Reduced Iron from 0.5 to 3 wt. % and a DRI manufacturing equipment including a DRI shaft (1) and a hydrogen separation unit (5), wherein said hydrogen separation unit (5) inlet is connected to a coke oven gas supply (6) and includes a first outlet connected to the DRI shaft to inject hydrogen separated from said coke oven gas and a second outlet connected to the transition section of said DRI shaft (1) to inject at least part of the remaining part of such coke oven gas.

Abstract: A method for manufacturing Direct Reduced Iron wherein iron ore is reduced in a DRI shaft by a reducing gas including hydrogen obtained by thermal cracking of methane inside a plasma torch, the reducing gas further including top gas coming from the DRI shaft and a DRI manufacturing equipment including a DRI shaft (1) and a plasma torch (40), wherein the plasma torch is connected on one side to a methane supply (41) and, on the other side, to the DRI shaft (1), the DRI shaft being provided with a recycling loop allowing to inject its top gas back in the DRI shaft.

Abstract: The present invention discloses a method and an apparatus for reactivating lime-based sorbents and increasing the carbon dioxide-capture capacity of the sorbent in the combustion of carbon-containing fuels. The method of the present invention seeks to increase the carbon dioxide capture capacity of lime-based sorbents by applying concentrated or 100% carbon dioxide directly to a lime-based sorbent. Optionally, the lime-based sorbent may be pretreated using a hydration process after each process of carbon dioxide separation. The regenerated sorbent is carbonated in a presence of concentrated carbon dioxide and elevated temperatures. The invention is useful in reducing the need to add additional sorbent to maintain the carbonation/calcination cycle. The regenerative potential of the sorbent as manifested by the present invention leads to increased carbon dioxide-capture capacity of the sorbent.
