In the process for producing fatty alcohol as described in EP 0737664 B1 a liquid intermediate product consisting of at least 50 wt % wax ester is produced from a liquid starting mixture containing fatty acid at temperatures of 120 to 320° C and pressures of 20 to 400 bar[a] which is hydrogenated by adding hydrogen and by admixing fine grain catalyst and a raw product consisting of at
iron DRI or sponge iron The reaction takes place in a shaft furnace a type of furnace that uses gas reductants to make DRI The operating temperature can be fairly low around 800°C The DRI is then fed into an EAF and turned into steel by further processing it and adding carbon As an interim technology to pave the way towards
The Manufacturing Process Formation of the absorbent pad 1 The absorbent pad is formed on a movable conveyer belt that passes through a long forming chamber At various points in the chamber pressurized nozzles spray either polymer particles or fibrous material onto the conveyor surface
Given the potential deficit of high quality raw materials growth in the DRI industry will have to be accompanied by a change in the manufacturing process Increasingly DRI will need to be made with lower quality iron ore which will then need to be upgraded—most likely using a smelting process—to make it more suitable for use in basic oxygen furnaces Exhibit 4
