The influence of abundant calcium oxide (CaO) addition on oil sand pyrolysis was firstly studied by thermogravimetric analysis (TGA) and in a fixed bed reactor. CaO additives calcined from analytically pure CaCO3 (named A) and oil sand minerals (named B) were compared with the addition ratio at 1:1 (oil sand:CaO, mass ratio). Observed by TGA, abundant addition of CaO would inhibit the devolatilizing...
In this paper, the direct reduction of iron ore (DRI) with the lignite solid char in vertical furnace were investigated on different conditions, such as reduction temperature, residence time, ratio of solid char to iron ore. It is found that, at the range of 800∼950°C, the degree of total iron (Fe%) and metallization (M%) increased with the temperature increasing, relatively, when the temperature...
In this work, based on the information of high concentration phenol-wastewater that was produced in the pyrogenation process of oil shale to prepare shale oil, Shale Oil phenol-wastewater was replaced by phenol and methyl phenol simulation wastewater. Experiments were used to investigate effect of one methyl phenol on phenol extraction yield from simulation wastewater by using two kinds of extraction...
