Upgrading of heavy oil with water has been reported using various catalysts, such as nickel potassium2)～4), cerium oxide5),6), titania_zirconia7), and iron oxide8)～21). Iron oxide is inexpensive and is a candidate catalyst for industrial upgrading of heavy oil with water. We previously developed a zirconia-supporting iron
The utilization of low-grade manganese ores has become necessary due to the intensive mining of high-grade ores for a long time. In this study, calcined ferruginous low-grade manganese ore was selectively reduced by CO, which converted hematite to magnetite, while manganese oxide was reduced to MnO. The iron-rich component was then separated by …
for upgrading ultrafine Egyptian iron ore using different starches as flocculants is investigated considering both grade and recov ery. This is done using the Fuerstenau upgrading curve. The upgrading curves. In general, the upgrading curves are used for characterization, for analysis and/or for comparing the
Iron is an essential element for cellular life, and yet free iron is a source of cellular damage and toxicity. To meet but not exceed daily iron requirements for erythrocyte production and cellular metabolism (25 mg/day), iron is absorbed via the diet (1-2 mg/day) and salvaged from erythrocyte breakdown by macrophages (20-25 mg/day); any remaining iron requirements are …
In the hydrothermal upgrading of heavy oil in a porous medium with 2000 mD permeability and 25 % porosity, iron oxide nanoparticles shown significant upgrading effect at 240 °C, where 9.5 wt% of the heavy fraction was converted to light fraction, and had excellent performance in promoting the conversion of high carbon number hydrocarbon to low ...
