20150136651 | DESORPTION OF BITUMEN FROM CLAY PARTICLES AND MATURE FINE TAILINGS - A method for desorption of bitumen from clay particles. Also a method for the desorption of asphaltenes from clay particles and a method for the desorption of bituminous fractions from mature fine tails (MFT). The method for desorption of bitumen from clay particles involves interacting, in a suitable organic solvent, a clay-bitumen composite with a compound capable of stabilizing the bitumen in the organic solvent and adsorbing to clay particles such that the compound replaces the bitumen in the clay-bitumen composite. A substantial amount of the compound that is capable of stabilizing the bitumen in the organic solvent is recovered with the clay particles, while the bitumen is released. Similarly, the method for desorption of asphaltenes from clay particles also involves interacting a clay-asphaltene composite with a compound capable of stabilizing the asphaltenes in an organic solvent, recovering the compound with the clay particles, and releasing the asphaltenes into solution. | 05-21-2015 |
20140350275 | MIXED-VALENT TRANSITION METAL-PHOSPHORANIMIDE CATALYSTS - Phosphoranimide-metal catalysts are disclosed. The catalysts comprise first row transition metals such as nickel, cobalt or iron.

The electronic state of the clusters can be adjusted to optimize catalytic activity for a range of commercially important reductive transformations, including hydrodesulfurization. A method of synthesis of these catalysts by anionic metathesis of a halide substituted precursor followed by oxidation is also disclosed. | 11-27-2014 |
20140346087 | CATALYSTS FOR HYDRODESULFURIZATION - Phosphoranimide-metal catalysts and their role in hydrodesulfurization and hydrogenation are disclosed. The catalysts comprise of first row transition metals such as nickel, cobalt and iron. The catalysts have a metal to anionic phosphoranimide ratio of 1:1 and have no inactive bulk phase and no dative ancillary ligands. In one embodiment, the catalysts comprise discrete mixed-valent precatalyst clusters, the electronic state of which can be adjusted to optimize catalytic activity. The catalysts catalyze the hydrodesulfurization of a range of sulfur-containing organic compounds under lower temperature and pressure conditions than those conditions commonly used in industrial hydrodesulfurization. The catalysts also catalyze the hydrogenation of substrates comprising at least one carbon-carbon double bond which is not present in an aromatic moiety, although the substrate itself may include an aromatic moiety. | 11-27-2014 |
