| 20110084002 | PROCESS FOR THE REMOVAL OF SULFONES FROM OXIDIZED HYDROCARBON FUELS - Described herein is a process for the removal of sulfones by mesoporous silica adsorbents having narrow pore size distribution which could be controlled to specification for the selective removal of sulfones from oxidised hydrocarbon fuels wherein the sulfones were present due to oxidative conversion of organo-sulfur compounds by a suitable oxidizing solution. The mesoporous adsorbents showed typically 2-18 times higher equilibrium loading capacity for sulfones in comparison to the commercially available adsorbents. | 04-14-2011 |
| 20110220552 | METHOD FOR REMOVING CORROSIVE SULFUR COMPOUNDS FROM A TRANSFORMER OIL - A method removes corrosive sulfur compounds from transformer oil. By adding a mixture of rare earths containing aluminum oxide and aluminum silicate to the transformer oil, and enriching the same with an aqueous solution of soluble metal salts, the corrosive sulfur compounds in the transformer oil are neutralized with defined heating and cooling phases. Advantageously, no additional chemical components, such as passivators, are added to the transformer oil. When using a tank for receiving the mixture of the rare earths containing aluminum oxide and aluminum silicate, the reaction can run in the tank. Any aging products that may be present, and the bonded corrosive sulfur compounds are effectively retained within the tank by a filter system, and can be disposed of with the tank. | 09-15-2011 |
| 20130126394 | IRON OXIDE MAGNETIC NANOPARTICLE, ITS PREPARATION AND ITS USE IN DESULFURIZATION - The present invention provides a method of preparing an iron oxide magnetic nanoparticle, comprising the steps of: i) reacting a water-soluble ferrous salt with a water-soluble ferric salt in a mole ratio of 1:2 in the presence of a base and a citrate to give an iron oxide particle surface-coated with the citrate (c-MNP); ii) reacting the c-MNP obtained in step (i) with a thiophilic compound to give a thiophilic compound-bounded iron oxide particle surface-coated with the citrate (thiophilic-c-MNP); and iii) modifying the thiophilic-c-MNP obtained in step (ii) using a surfactant for phase transfer of the thiophilic-c-MNP from aqueous phase to organic phase.

The catalysts contain one or more reactive metal salts dispersed on one or more substrates. Suitable reactive metal salts include those salts containing multivariable metals having variable valence or oxidation states and having catalytic activity with sulfur compounds present in gaseous fuel streams. In some embodiments, the catalyst contains one or more compounds that function as an oxygen sponge under the reaction conditions for oxidative sulfur removal. The catalysts can be used to oxidatively remove sulfur-containing compounds from fuel streams, particularly gaseous fuel streams having high sulfur content. Due to the reduced catalyst cost, anticipated long catalyst life and reduced adsorbent consumption, the catalysts described herein are expected to provide a 20-60% reduction in annual desulfurization cost for biogas with sulfur contents ranges from 1000-5000 ppmv compared with the best adsorbent approach. | 01-29-2015 |
