In relative to the single metal oxide-based oxygen carrier (OC), combined OC owned superiority for CLC of coal. In this research, combined NiFe2O4 OC was synthesized using sol–gel combustion synthesis method, and its reaction with a typical Chinese high-sulfur coal as Liuzhi (LZ) coal was ...
The most probable explanation for this result would be the improper use of the Natelson Microgas Analyzer which was used to analyze the dissolved oxygen in the water. With this complete lack of precision in the oxygen data, it was decided that no analysis would be conducted with it, and ...
Here, a stream of finely divided oxygen-containing gas is combined under agitation with the liquid sulfur to reduce residual sulfide/polysulfide concentration. Unfortunately, while such methods is at least conceptually effective, significant material and complexity is required. Similar problems are ...
In an alteration of the oxyfuel method, additional heat is generated with the addition of aluminum, preferably liquid aluminum, and with combustion of oil sand (instead of oil or coal) with oxygen (O2) and, if needed, also nitrogen (N2) (Wacker accident). If the nitrogen coupling to ...
(−43 °C to 45 °C) were obtained, and they have variable mechanical properties, some of them are flexible and elastic, and some of them are stiff and relatively strong, which can be accurately controlled by chain length of linear segment of crosslinker combined with molar ration of...
The cell membrane is impermeable to viruses—to get inside and infect a cell, they use a range of strategies to exploit the cellular and biochemical properties of the membranes. The thiol-mediated uptake of organic molecules similar to alcohols, where oxygen is replaced by a sulfur atom, is ...
oxygen functional groups on rGO provided anchoring sites to trap the soluble polysulfide intermediates within the electrode. Very impressively, the GF-rGO/S cathodes with a sulfur loading of 9.8mgcm−2and sulfur content of 83wt% showed a high areal capacity of 10.3mAhcm−2at 0.2C with ...
We use the anaerobic part of Xuet al.33’s experiments (referred to as the batch experiments), in which simultaneous reduction of both nitrate and sulfate are reported, along with nitrite concentration throughout the experiments. We use the anaerobic part since oxygen is considered to be negligi...
The invention provides an energy-saving combined ore dressing process for high-oxidation and high-bonding oxygen and sulfur mixed copper ore. The process comprises the steps of raw ore treatment, preparation of leaching solution, stirring and leaching, dynamic soaking selection, solid-liquid separation...
