A interesting phenomena is that (NH4)2S2O8 treatment affected micorpore structure of coal-base carbon but little influenced on micropore structure of coconut shell carbon, because the acidic oxidant dissolved ash in coal-base AC and changed its porosity.
The experiments of desulfurization had been done by using Baorixile char as catalytic agent under the condition of simulated flue gasThe results shown that char has high reactivity,especially,when the char was modified by copper sulphate,the SO2 transform can reach 871% in average,which exceeded common coal-base actived carbon,and close to that of coconut shell and furfural dregs actived carbon
A series of experiments were carried out in the department laboratory and showed that using fixed bed jar method the coal base reduction of poor siderite can produce reduction ore. by ball milling and magnetic separation the sponge iron(TFe>80%,SiO 2<6%) was obtained.
The DRC coal base direct reduction ironmaking technology from Davy International Engineering Co. will be adopted by the DRC Direct Reduction Ironmaking Plant at Tianjin Steel Tube Co The DRI will be produced in rotary kiln using ore,coal and lime.
The interactions of CH4 on different rank coals surface were mainly studied by the abinitio quantum chemistry method MP2.The result shows that the interacting energy of different rank coals increase with methane increasing gradually along with the coal base diameter. Unified the space physical properties of different rank coals,the results of different rank coals adsorption isothermal experiment are also explained from the microscopic angle.
From the resources, technology, environment protection, economic and other applied five areas, the paper stated the energy advantages of the new coal base clean combustion fuel coal water mixture. The paper analyzed that coal water mixture would be the first area to be applied.
The present study focused on the development of a full-scale gas turbine combustor burning syn-gas from the coal-based multi-production.
The technology of coal-based direct reduction of high-iron-content red mud is studied.
An innovative process for direct reduction of cold-bound pellets from Iron concentrate with a coal-based rotary kiln
Industrialization and urbanization since the early 1980s have imposed structural constraints on its traditional coal-based energy supply model.
The Federal Government's efforts to induce development of a coal-based synthetic fuel industry include direct subsidies, tax concessions, and assurances that it will purchase the industry's output, even if above the market price.
The columns were found to tolerate samples of up to 5 μg with little loss of efficiency and were used in the high-resolution separation of coal-derived fluids.
Implications of on-line FTIR detection in the separation of coal-derived products via HPLC with polar modifiers
A polar fraction of a coal-derived product is also chromatographed under identical conditions.
Group-type separation and determination of phenolic compounds in coal-derived products by HPLC
A rapid method was developed for the direct extraction of phenolic compounds from coal-derived products and subsequent isocratic HPLC analysis in a reversed-phase system by using the backflush technique.
